hi! i was interested in a topic and i realized you were probably one of the better people to ask. what resources would you recommend for studying the impact of christianity on sex and sexuality?
the oxford handbook of theology, sexuality,and gender is invaluable, but i'm unsure if there has been a new edition since 2014.
historical texts: if you are an absolute beginner, the chapter sexuality in christian traditions by adrian thatcher, in the cambridge world history of sexualities: volume ii is a good, solid overview. additionally: contextualizing gender in early christian discourse by caroline stichele and todd penner. christianity and sexuality in the early modern world by merry wiesner-hanks, sexual desire and love: origins and history of the christian ethic of sexuality and marriage by erich fuchs.
critical + liberation theology: god, sexuality and the self by sarah coakley, touching our strength by carter heyward, indecent theology by marcella althaus-reid, why women need the goddess by carol christ, sexuality and the black church: a womanist perspetive by kelly b douglas, enfleshing freedom: body, race, and being by m. shawn copeland, postcolonial imagination and feminist theology by kwok pui-lan, queering christ: beyond act up by robert e. goss, the good news of the body edited by lisa isherwood, theology and sexuality by susanna cornwall, queer theologies: the basics by chris greenough, our lives: a womanist queer theology by pamela r lightsey.
critical issues in sexuality: the making of biblical womanhood by beth allision barr, #churchtoo: how purity culture upholds abuse and how to find healing by emily joy allison, the cry of tamar by pamela cooper-white (NB: don't know why google books doesn't have the most recent second edition), jesus and john wayne by kristin du mez, catholic sexual theology and adolescent girls by doris m kieser, black gay british christian queer by jarel-robinson brown.
additionally, am extremely excited about the release of lower than the angels by diarmaid macculloch in april: i would keep an eye out for its release and try to read it if you can, as i suspect it's going to be an excellent, critical historical overview.
there are, of course, gaps in my recs, but everything i recommend here i consider essentially introductory. you'll find some of this work is focused more on gender, but we cannot discuss sexuality without also discussing gender; additionally, the majority of non-white theologies (womanist, east asian, indigenous) are engaging with gender rather than sexuality at this point in their respective developments.
