Well, the Stoics date from the 3rd century BC, not the 3rd century AD, and was popular in Rome before 300 AD. There was actually a pretty early adaptation of Stoic philosophy to Christianity. You saw Stoic ideas in Christianity as early as 100-150. It also probably a mistake to associate disapproval of homosexuality solely with Stoicism. While the later Stoics did disapprove of homoseuxality, so did a lot of other Greek and Roman philosophies at the time, and so did the Judaism that Christianity had its origins in.
Ava, I’m quite familiar with church history, thank you, and I understand the interpretation of it that you are sharing. However, I did not post here to debate the topic, only to respond to Poly’s invitation to share my reaction to his OP.
Pun, a nitpick: There are two states of sexual activity that are considered “right” by all Christian churches (except the Shakers): celibacy, and sexual relations within a committed ‘marital’ relationship. The Episcopal Church has moved ahead of most of the rest of the Anglican Communion and the majority of other Christian denominations by acknowledging that there are times when a formal commitment to a marital relationship before God cannot be accompanied by a legal “marriage.” An example besides gay relationships is a widowed couple in love, barely making a go of it on their pensions, with hers structured to stop if she remarries and them incapable of living on his alone. And, of course, there is recognition of the fact that young people will often enter into such bonds with each other in advance of legalizing them by a marriage license or making formal lifelong commitments in church. My distinct impression is that you and fizzes are as committed to each other as you’re going to get, in your own minds – the future legal authentication and the formal cimmitment before God are the acknowledgement of that commitment, not the making of it – which means that your sex life is not sinful in Episcopalian eyes, for what that’s worth to you.
