Christianity, Sexuality, and Shame: From Patristic Theology to Empirical Psychology

A Literature Review for the Vela Research Program

Cross-validated from two independent parallel drafts · 24 April 2026

Abstract This literature review synthesises the historical-theological and modern empirical literatures bearing on the relationship between Christianity, sexuality, and shame. Its specific purpose is to build a bridge that the Vela corpus syntheses — three documents generated from a 1,692-passage library on patristic, medieval, and Reformation Christianity — explicitly identify as missing: the connection between historical-theological narrative (Augustine as pivot, pre-Christian Mediterranean asceticism, the Pelagian controversy, East/West divergence) and modern peer-reviewed research in the psychology of religion, empirical sexology, and purity-culture studies. The review documents the historical backbone against its strongest academic sources; identifies the empirical mechanism linking religious formation to sexual shame (sex guilt as mediator; moral incongruence as the best-supported contemporary model); characterises purity culture as an increasingly measurable research object with documented harms; surveys the available measurement infrastructure; compares traditions empirically where data exist; and examines the reclamation literature alongside the question of whether theological alternatives actually reduce shame outcomes. Three overarching conclusions emerge: the historical claim is strong; the empirical mechanism is now reasonably well characterised; and the intervention evidence — whether theological reinterpretation can undo what theological formation installs — remains almost entirely absent.

  1. Introduction The three Vela corpus syntheses generated on 23 April 2026 draw on a library of lectures, biographies, and historical studies to construct a coherent narrative about Western Christianity's relationship to sexuality. That narrative identifies Augustine of Hippo as the pivotal figure who transformed pre-existing Mediterranean anxieties about bodily control into distinctively Christian theological categories of sin and concupiscence; traces the contested and sometimes contradictory reception of Augustine through medieval canon law and the Reformation; and documents the East/West divergence that left the Greek church largely unaffected by the Augustinian settlement. The syntheses are strong on historical narrative and explicit about their gaps: they cannot connect to modern empirical psychology, cannot measure the outcomes of the theology they describe, and cannot address the contemporary literature on purity culture, religious-sexual shame, or whether theological alternatives change anything measurable. This review closes those gaps. It does not re-litigate the historical claims but positions them against the strongest available academic sources, identifies the empirical counterparts to the theological constructs the corpus describes, and names the research questions that remain unaddressed by either the historical or the empirical literature alone. The review draws on two independently produced parallel literature maps that were subsequently reconciled; where they disagreed on a citation or DOI, the more conservative position is adopted and the discrepancy noted.

  2. Historical-Theological Foundations 2.1 The pre-Christian substrate The corpus synthesis's central claim — that Christianity neither invented sexual shame nor merely inherited it unchanged, but transformed existing Mediterranean anxieties into distinctively Christian theological categories — is supported by the most rigorous modern historical scholarship on late antiquity. Peter Brown's (1988) The Body and Society remains the foundational secondary source. Brown documented the extraordinary degree to which bodily control and sexual renunciation were already valued across Greco-Roman philosophical schools, Jewish Hellenism, and early Christian asceticism before Augustine consolidated a specifically theological account. The corpus's phrasing that the late antique Mediterranean was "a special hothouse for bodily control" tracks Brown's argument directly. Kyle Harper's (2013) From Shame to Sin provides the most rigorous analytical framing for the corpus's central historical thesis: that the specifically Christian contribution was not the introduction of sexual anxiety but the transformation of the Mediterranean's honour-shame logic into a new moral vocabulary of sin, conscience, and interiority. Harper's argument is that ancient Greco-Roman sexual ethics operated through public honour — what others see and judge — while Augustine and his successors constructed a system in which the transgression is internal and theological, persisting even without social witness. This is the most important single historical claim the corpus makes, and Harper's scholarship is its strongest academic support. Virginia Burrus's (2008) Saving Shame complicates the linear narrative that Christianity simply converted shame into guilt. Burrus argues that shame itself remains constitutive within Christian cultures and subject-formation — that the transition was not from shame to guilt but a transformation of shame's objects and mechanisms. This complication does not invalidate the corpus synthesis but requires that the shame-to-sin thesis be stated with care: shame did not disappear from Christian moral psychology; it was redirected, intensified, and theologically grounded. 2.2 Paul and Augustine The corpus's characterisation of Paul as pragmatic rather than systematically anti-sex is consistent with the mainstream of New Testament scholarship and with MacCulloch's (2024) comprehensive history Lower than the Angels. Paul's sexual ethics are important but not yet the decisive architecture of later Western sexual anxiety; they become that only through subsequent interpretation, particularly Augustine's anti-Pelagian reading of Romans. The corpus correctly identifies the interpretive leap rather than the original text as the generator of Western sexual shame. Brown's (2000) Augustine biography provides the strongest support for the corpus's portrait of Augustine: a figure whose sexual theology emerged from biographical experience (the concubine relationship, the conversion, the break from Manichaeism), pastoral context, and above all polemical controversy. The Pelagian conflict drove Augustine to "extremes of statement" — the phrase is MacCulloch's and tracks the corpus synthesis precisely — developing his mature doctrines of concupiscence and original sin in the late 390s and early 400s under pressure from Julian of Eclanum's pointed challenges. The corpus's insistence that many positions attributed to "Augustinian sexual theology" may be post-Augustinian scholastic elaborations is supported by Brundage's (1987) Law, Sex, and Christian Society in Medieval Europe, which documents in detail how medieval canon lawyers systematised and often intensified what Augustine had argued more tentatively. The corpus also registers a finding that the popular account consistently misses: O'Donnell's (2005) Augustine biography, which the corpus drew upon directly, argues that Augustine's position was not that sexuality is evil but that it is good but disordered — disrupted by the Fall, not condemned as matter. The distinction matters. The shame architecture the Vela platform is ultimately interested in — the installation of guilt in the gap between lived sexual experience and an impossible theological standard — is better traced to the concupiscence doctrine than to any outright condemnation of sex as such. 2.3 East/West divergence and institutional transmission The corpus synthesis identifies the East/West divergence as a gap it cannot fill: why did Augustine's settlement become dominant in the Latin West while Greek Christianity followed a different path? The academic literature offers two partly complementary answers. The first is linguistic and cultural: Ambrose of Milan read Greek and corresponded with Eastern theologians; Augustine was largely confined to Latin sources and developed his theology in intellectual isolation from the Greek tradition. The second is institutional: the Western church developed a more systematically canonistic approach to marital-sexual regulation than Byzantium, producing the elaborated machinery of confession, penance, and canonical impediment that Brundage documented. Perisanidi's (2017) study of the marital debt in Byzantium is the most specific recent contribution to this comparison: she demonstrates that Byzantine canon law treated the conjugal debt differently from its Western counterpart, with less systematically coercive enforcement — an institutional difference with direct implications for how sexual shame was produced and maintained. Stan and Turcescu's (2010) empirical-historical article on Eastern Orthodox views on sexuality and the body complicates any simple reading of the East as sex-positive relative to the West. Orthodox sexual theology is restrictive but differently so: shaped by patristics, canon law, and contemporary ecclesial pronouncement rather than Latin Augustinianism, it produces its own shame architecture through different doctrinal routes. The practical implication for cross-tradition empirical research is that "non-Augustinian" does not mean "non-shaming," and Orthodox populations cannot be used as simple shame-negative controls for studies of Western Catholic or evangelical Protestant populations.

  3. The Empirical Psychology of Religion and Sexuality 3.1 Measurement infrastructure The corpus syntheses operate entirely at the level of doctrinal history and cannot connect to the psychology of religion without measurement infrastructure. The Duke University Religion Index (DUREL; Koenig & Büssing, 2010) is the most widely used brief instrument for operationalising religiosity in epidemiological and psychological research, measuring organisational religious activity, non-organisational practice, and intrinsic religiosity. It is not sexuality-specific, but it is the standard bridge variable for linking theological-historical claims to contemporary quantitative datasets, and any empirical programme that attempts to test the corpus's historical claims against present-day populations will need it. An equally important finding from the religiosity measurement literature is that the label of religious affiliation — Catholic, Protestant, LDS, Orthodox — explains substantially less variance in sexual outcomes than the intensity and style of religiosity within traditions. Farmer, Trapnell, and Meston (2009) showed that dimensional religiosity (intrinsic religiosity, fundamentalism, spirituality) predicts sexual behaviour and attitudes better than nominal affiliation. Ahrold, Farmer, Trapnell, and Meston (2011) replicated this finding for sexual fantasy, showing that religiosity dimensions predict the content and frequency of sexual fantasy with more precision than group membership. The implication for the corpus syntheses is that the doctrinal tradition a person belongs to is a weaker predictor of their sexual shame than how seriously they hold and enact that tradition. 3.2 The central mechanism: sex guilt and moral incongruence Murray, Ciarrocchi, and Murray-Swank (2007) provided the most direct empirical bridge between the constructs the corpus describes historically and their measurable psychological counterparts. In their study, religiosity and spirituality predicted sexual attitudes and some sexual behaviours, but alienation from God — a specifically theological construct with no secular parallel — was the strongest predictor of sexual shame and guilt. This finding is theoretically important: it suggests that the shame mechanism does not operate through religiosity generally but through a specific relationship between the believer's sense of self and their sense of God's view of them. The Augustinian inheritance — the God who sees the concupiscent heart — is reproduced at the individual psychological level in the experience of divine alienation. Woo, Morshedian, and Brotto (2012) identified the specific mechanism through which this operates on sexual function: sex guilt mediates the relationship between religiosity and sexual desire. Higher religiosity predicts lower sexual desire, and this relationship is statistically explained by sex guilt — the internalised belief that sexual pleasure is wrong. This is the corpus synthesis's shame-installation mechanism rendered in path-analytic form: the theology produces guilt, the guilt reduces desire, and the reduction of desire is experienced as a moral achievement by those who cannot easily separate theological virtue from psychological inhibition. Grubbs and Perry's (2019) moral incongruence framework is the best-supported contemporary model for understanding religion-linked sexual shame. The framework proposes that distress about sexual behaviour — particularly pornography use, but extending to any sexual activity that violates internalised moral standards — is driven not by the behaviour itself but by the gap between the behaviour and the person's religious-moral self-concept. Higher religiosity produces stricter moral standards; stricter moral standards increase the probability that any given sexual behaviour will produce moral incongruence; moral incongruence produces shame, distress, and compulsivity-like self-appraisal. Grubbs et al.'s (2022) preregistered registered report provides the highest-confidence contemporary evidence for this mechanism, demonstrating that moral disapproval predicts perceived addiction-like appraisal of sexual behaviour at a level that exceeds actual use frequency as a predictor. The theology is doing more causal work than the behaviour. Jennings et al.'s (2021) systematic review of compulsive sexual behaviour and religiosity found small-to-moderate and inconsistent associations across studies, with moral-disapproval dynamics recurring as the more robust finding than any direct religiosity-compulsivity link. This is consistent with the moral incongruence model: it is not that religious people have more compulsive sexual behaviour, but that they appraise their behaviour as more compulsive because their moral standards classify more behaviour as transgressive. 3.3 The sanctification pathway: religion as shame reducer The literature reviewed above describes religion as a shame-producer through sex guilt and moral incongruence. An equally important finding from the same empirical literature is that religion can reduce shame and increase sexual wellbeing through what Mahoney, Pargament, and colleagues have called the sanctification of sexuality — the attribution of sacred meaning to sexual experience within committed relationships. Murray-Swank, Pargament, and Mahoney (2005) showed that sanctification of sexuality in college students predicted more integrated sexual experience and lower shame. Hernandez, Mahoney, and Pargament (2011) demonstrated in newlywed samples that sanctification of marital sexuality predicted higher marital and sexual quality. Hernandez-Kane and Mahoney (2018) showed these effects were longitudinally stable rather than cross-sectional artifacts. The synthesis that brings these two pathways together is Leonhardt, Busby, and Willoughby's (2020) study, which showed that religiosity predicts both pathways simultaneously: higher religiosity predicts worse sexual outcomes when its effects are mediated by sex guilt, and better outcomes when mediated by sanctification. Religion is a double-edged instrument: the same tradition that installs the guilt that produces shame also offers the sacred framework that — when successfully internalised — reduces shame. Whether a given individual experiences predominantly the guilt pathway or the sanctification pathway depends on how their religious formation specifically operationalised the theology. This is the most important finding for anyone designing a research programme around the Vela corpus: the historical claim (Augustine installed a shame architecture) and the empirical finding (religion can both produce and reduce shame) are not in contradiction. They describe different mechanisms that a single religious tradition can activate, often in the same person at different stages of life.

  4. Purity Culture as a Modern Research Object 4.1 The qualitative foundation Linda Kay Klein's (2018) Pure is the foundational text for naming "purity culture" as a distinct modern evangelical socialisation regime. Based on interviews with more than a hundred women raised in evangelical purity movements, Klein documented a pattern of shame, fear, bodily alienation, and difficulty with sexual function in committed adult relationships that she traced directly to the purity-pledge, modesty-culture, and sexual-danger narratives of evangelical youth ministry. Klein's work provided the conceptual vocabulary — "purity culture" as a coherent sociological object — that subsequent empirical research has operationalised and tested. Her contribution is foundational and irreplaceable as a qualitative record of lived experience, even though it cannot by itself establish causal mechanisms. 4.2 Measurement: the Purity Culture Beliefs Scale The most important psychometric contribution to this literature is the Purity Culture Beliefs Scale (PCBS), developed and validated by Ortiz, Sunu, Hall, Anderson, and Wang (2023). The PCBS operationalises purity-culture internalisation as a measurable construct with established convergent validity against shame, rape-myth acceptance, and related constructs. Its development means that the field can now move beyond qualitative description and self-selected samples: researchers have a reusable instrument for quantifying the degree to which any given respondent has internalised the specific purity-culture sexual ethic, independent of their current denominational affiliation. For the Vela research programme, the PCBS is the most important new instrument in the field: it provides the direct psychometric bridge between the theological history the corpus documents and the individual psychology the platform aims to measure. 4.3 Empirical outcomes The empirical purity-culture literature has documented harms across multiple outcome domains. Owens, Hall, and Anderson (2021) showed that purity-culture endorsement predicts rape myth acceptance — the misattribution of responsibility for sexual assault to victims — in Christian samples. Sawatsky, Lindenbach, and the Gregoires (2025) provided large-N evidence that purity-culture trope endorsement is associated with lower marital satisfaction, lower sexual satisfaction, and greater experience of sexual pain specifically among white Christian women, moving the literature from narrative complaint to measurable outcome burden. Muskrat et al. (2025) documented that purity culture's effects are particularly severe for sexual and gender minority people socialised as women in evangelical contexts, producing shame, concealment, and unresolvable conflict over embodiment and desire. Coates, Metcalfe, and Meston (2026) identified what may be the most clinically consequential finding in the literature: childhood purity-culture exposure independently predicts sexual shame among survivors of nonconsensual sexual experiences, even when trauma history is modelled as a covariate. The purity architecture does not merely create shame in normal sexual development; it amplifies shame in the context of sexual harm. The virginity-pledge literature provides the longest longitudinal view of purity-culture outcomes. Brückner and Bearman (2005) showed that pledge-takers who broke their pledge had STI rates comparable to or higher than non-pledgers because they were significantly less likely to use contraception — the purity framework produced neither the behaviour change it promised nor the sexual health protection it claimed. McKenna and Nedelec (2024) extended this longitudinal picture by showing that virginity-pact effects are gendered, with different downstream associations for women and men regarding later sexual victimisation. The accumulated evidence supports the conclusion that purity-culture socialisation does not protect sexual health and produces measurable psychological harms, particularly for women and for sexual and gender minority individuals.

  5. Measurement Infrastructure The empirical psychology of religious sexual shame currently lacks a single gold-standard validated instrument. Both parallel literature maps concluded independently that no peer-reviewed, field-standard measure cleanly named a "religious sexual shame scale" can be identified at present. The field instead relies on a cluster of adjacent instruments that collectively triangulate the construct. The Sex Guilt subscale of Mosher's forced-choice inventory has been the dominant guilt measure since the late 1960s and has accumulated the largest empirical database, but it measures sexual guilt broadly without specifically operationalising its religious sources. Gordon's (2018) Male Sexual Shame Scale addresses a specific gap by providing a validated multidimensional measure of sexual shame specifically for men, who have been underrepresented in shame research. Seebeck's (2021) Sexual Shame Inventory and Lim's (2019) validation of the Kyle Inventory of Sexual Shame represent dissertation-level contributions that have not yet achieved full peer-reviewed field-standard status. The Purity Culture Beliefs Scale (Ortiz et al., 2023) is currently the most useful religion-specific instrument for quantifying a modern evangelical formation likely to generate sexual shame. The sanctification-of-sexuality measures developed in Pargament's laboratory operationalise the positive pathway: the attribution of sacred meaning to sexual experience that predicts better rather than worse outcomes. The Sexual Minority and Religious Identity Integration scale (SMRII; Etengoff et al., 2024) provides the most directly relevant instrument for quantifying whether religious and sexual identities are experienced as integrated or conflictual, making it the key tool for intervention research testing whether theological reinterpretation changes outcomes. The Grubbs moral incongruence framework adds a behavioural dimension: the Religious and Moral Disapproval subscale, embedded in Grubbs's pornography-use research, operationalises the specific appraisal mechanism — this behaviour violates my religious-moral self-concept — that appears to be the proximate cause of religious sexual shame. Taken together, these instruments provide a reasonably complete measurement toolkit for the empirical programme the corpus syntheses call for, even though no single instrument captures the full construct.

  6. Cross-Tradition Empirical Comparisons The corpus syntheses focus almost exclusively on Western Latin Christianity and acknowledge the East/West divergence as a gap. The empirical psychology-of-religion literature provides a more differentiated picture, though with important unevenness in coverage across traditions. Rigo and Saroglou's (2019) comparative study across Christian and Muslim samples showed that religiosity dimensions predict restricted sexual behaviour, sexual guilt, and reduced sexual pleasure-seeking in both traditions — the same mechanism operating across doctrinal systems. This finding suggests that the Augustinian doctrinal genealogy is not necessary to produce the pattern of shame the corpus traces historically; the mechanism (internalised religious prohibition producing guilt-mediated inhibition) may generalise across conservative religious traditions. However, the purity-culture literature is specifically evangelical Protestant in its character, and the PCBS was developed in that context. Whether the specific purity-culture shame architecture — modesty culture, virginity pledges, "true love waits" — is generalisable to Catholic, Orthodox, or LDS contexts requires separate empirical investigation. For Latter-day Saint populations, McKiernan et al. (2022) documented patterns of sexual secrecy, inhibition, and later renegotiation in married couples, and Lefevor et al. (2023) demonstrated that identity-navigation strategies — the degree to which sexual minority and LDS identities are integrated rather than compartmentalised or conflicted — strongly predict health outcomes. The LDS data are consistent with the moral incongruence model: the shame operates through the gap between lived experience and internalised religious-moral standards, and integration reduces that gap. Kaplan et al.'s (2025) study of Orthodox Jewish adolescents provided an important cross-tradition comparison: moral disapproval of prohibited sexual behaviours combined with strong religiosity predicted sexual shame in this sample, replicating the mechanism the Christian literature documents in a non-Christian conservative religious context. Rosmarin and Pirutinsky's (2019) study of problematic sexual behaviour among adult Orthodox Jewish males showed similar dynamics. These comparative findings support the hypothesis that the mechanism — internalised prohibition producing shame through moral incongruence — is not Christianity-specific, while the specific content (which behaviours are prohibited, how explicitly they are policed) varies across traditions in ways that produce different shame profiles. Eastern Orthodox Christianity remains the most significant empirical gap in the cross-tradition literature. Stan and Turcescu (2010) provide theological-historical coverage, but no peer-reviewed quantitative study comparing Orthodox and Western Christian populations on validated sexual shame measures could be located in either parallel literature map. Given the corpus syntheses' explicit identification of the East/West theological divergence as a gap, this represents the field's most important unanswered comparative question.

  7. Theological Alternatives and the Reclamation Literature 7.1 Sanctification as empirically documented alternative The most empirically grounded theological alternative to shame-producing Christianity is the sanctification framework: the attribution of sacred meaning to sexual experience within committed relationships. As detailed in Section 3.3, this framework has accumulated convincing evidence across cross-sectional and longitudinal studies that it predicts better sexual and relational outcomes than the guilt pathway. Theologically, the sanctification framework draws on traditions that emphasise bodily creation as good (imago Dei), sexual union as covenant (Song of Solomon, the nuptial theology of John Paul II's Theology of the Body), and pleasure within marriage as participation in divine creativity rather than as a concession to human weakness. What the empirical literature cannot yet tell us is whether exposure to the sanctification framework — through sermons, pastoral counselling, or theological education — causes people who previously held shame-producing frameworks to shift toward the sanctification pathway. The available studies measure the correlation between sanctification beliefs and sexual outcomes in samples who already hold those beliefs. The causal question — can the shame be therapeutically reduced through theological reframing? — remains unanswered. 7.2 The reclamation literature The reclamation literature — popular sex-positive Christian writing, feminist and queer theology, clinical pastoral models — addresses the same problem from the opposite end. Where the sanctification research asks what happens when sacred meaning is present, the reclamation literature asks what happens when shame-producing frameworks are actively challenged and replaced. Rosemary Radford Ruether's (1983) Sexism and God-Talk argued that the body-soul dualism driving Christian sexual shame is a Platonic contamination of authentic Christian anthropology, and that reclaiming the body as good is a theological recovery rather than a theological innovation. Sarah Coakley's (2013) God, Sexuality, and the Self offered a more technically sophisticated version of the same argument from within analytic theology, contending that properly understood, Christian asceticism was never about shame but about the redirection of desire toward its proper end. Both arguments follow the pattern the corpus synthesis identifies as characteristic of Christian reinterpretation: the claim to be recovering what was always true against a tradition of distortion. Tina Schermer Sellers's (2017) Sex, God, and the Conservative Church is the most directly clinical articulation of the reclamation approach: a model for treating religious sexual shame in conservative Christian contexts by theological reframing, with case histories but without controlled outcome data. Nadia Bolz-Weber's (2019) Shameless addresses the same problem at the popular level, arguing that Christian sexual shame is a heresy — not the tradition, but a distortion of it. The popular and clinical literatures are consistent in their diagnosis and in their proposed remedy (theological reinterpretation) but have not produced the outcome evidence that would allow a judgment about whether the remedy works. Anderson and Koc (2020) provide the closest available empirical proxy for the effects of affirming reinterpretation: they showed that identity integration — the degree to which religious and gay identities are experienced as compatible rather than conflictual — is associated with lower guilt and shame in religious gay men. This is not a study of theological intervention but a study of its outcome: people who have, by whatever means, achieved integration show lower shame. The Etengoff et al. (2024) SMRII scale makes it possible, in principle, to design and evaluate interventions that test whether integration can be achieved through deliberate theological reframing, community change, or pastoral counselling.

  8. Open Research Questions Five research questions emerge from the cross-validation of the two parallel maps as bridges that neither the historical-theological nor the empirical psychology literature has yet formally built. The first asks whether historically accurate information about Augustine's actual theological positions — specifically the distinction between "sexuality is good but disordered" and the popular caricature of outright sexual condemnation — reduces sexual shame in participants from conservative Christian backgrounds. The corpus synthesis extensively documents the gap between Augustine's actual arguments and their popular reception. No study has tested whether closing that gap at the individual level through education has measurable effects on shame scores. A pre-registered RCT comparing participants who receive historically accurate theological information with those who receive the popular caricature would directly test this. The second asks whether the East/West theological divergence the corpus documents produces different contemporary shame profiles in Eastern Orthodox versus Western Catholic and evangelical Protestant populations at matched levels of religiosity. The mechanism would be: if Augustinian concupiscence doctrine is the proximate theological cause of guilt-mediated sexual shame, Orthodox populations should show different shame profiles at equivalent religiosity levels because their theological anthropology differs. No published empirical study has conducted this comparison. The third asks whether purity-culture socialisation specifically operationalised through Augustinian rather than Arminian theological anthropology produces greater sexual shame than purity-culture socialisation in non-Calvinist evangelical contexts. The corpus documents that the Pelagian-Augustinian axis is empirically distinguishable — Arminian traditions represent a partial Pelagian recovery. If Augustinian depravity doctrine drives more shame than evangelical purity-behaviour norms, Reformed/Calvinist populations should show higher moral incongruence scores than Arminian/Wesleyan populations with equivalent purity-culture exposure. The fourth asks whether exposure to theological reclamation — specifically, pastoral engagement with sanctification-of-sexuality frameworks — produces measurable reductions in sex guilt and moral incongruence in individuals with prior purity-culture socialisation. The available evidence shows correlations between sanctification beliefs and better outcomes, and between identity integration and lower shame, but no controlled study has tested a theological reframing intervention against an active comparison condition. The fifth asks whether the purity-culture shame mechanism the corpus traces from Augustine through medieval canon law through American evangelicalism is continuous — a single causal chain whose strength can be predicted by the doctrinal distance from Augustine — or whether it is reconstructed in each generation through independent social mechanisms that happen to produce convergent outcomes. The historical claim implies the former; the empirical finding that the same mechanism operates in Orthodox Jewish contexts without any Augustinian heritage suggests the latter may be more accurate.

  9. Conclusions The literature reviewed here supports the historical-theological narrative the Vela corpus syntheses construct while significantly complicating its implied causal claims and substantially enriching its empirical counterparts. Three conclusions bear emphasis. First, the historical claim is strong but not simple. Harper's shame-to-sin thesis, Brown's documentation of pre-Christian ascetic currents, and Brundage's account of medieval legal elaboration together provide the academic scaffolding for the corpus's narrative. Burrus's complication — that shame did not simply become guilt but was transformed and re-grounded — is itself supported by the empirical psychology literature: modern shame measures and guilt measures are distinct, predict different outcomes, and respond to different religious constructs in the Murray, Ciarrocchi and Murray-Swank data. Second, the empirical mechanism is now reasonably well characterised. Religiosity produces sexual shame primarily through two routes: the sex guilt pathway (internalised belief that sexual pleasure is wrong, producing desire inhibition, documented by Woo et al., 2012) and the moral incongruence pathway (the gap between prohibited behaviour and religious self-concept, producing distress independent of behaviour frequency, documented by Grubbs and Perry, 2019, and confirmed in a registered report by Grubbs et al., 2022). The sanctification pathway demonstrates that the same religious tradition can produce the opposite outcome when it successfully frames sexual experience as sacred rather than threatening. Third, the intervention evidence is almost entirely absent. The reclamation literature — feminist theology, queer theology, Sellers's clinical model, Bolz-Weber's popular writing — makes plausible claims about what could reduce religious sexual shame if it worked. The closest empirical evidence is the identity-integration literature, which shows that achieved integration is associated with lower shame without establishing how to achieve it. The design and evaluation of theological reinterpretation as a clinical intervention remains the most important undone work in this field.
