Episode notes
Eucharistic Thought Drove Clerical Celibacy
- The 11th–12th century Eucharistic theology made the priest's role sacramentally central and pushed the church toward clerical celibacy.
- Celibate clergy made lay marriage the sole sphere for sexual activity and emphasized procreation as marriage's purpose.
Roots Of Early Christian Homophobia
- Christian hostility to same-sex relations stemmed from Jewish emphasis on procreation and ascetic Greek-influenced strands opposing sexual activity.
- Ancient same-sex practices were often unequal phases, different from modern lifelong partnerships.
Foucault Misreads Christianity And Sexuality
- Michel Foucault's history of sexuality underplays ancient Christianity and overstates modern invention of homosexuality.
- Earlier scholars like Boswell and Bray also overstated continuity of Christian hospitality to same-sex relations.
