Sex for Christians: Self-Giving and Sanctifying
"Next time you're near a time machine, I recommend traveling back to one of the earliest Christian churches—say, in 2nd-century Rome—and paying close attention to what you see and hear. You'll be struck, of course, by the diversity and the odd, sometimes troubling juxtapositions: Here is a community where slaves and slave owners are drinking from the same Communion cup, where the grip of Caesar's reign is loosened by a stronger cry: "Jesus is Lord." Here is a group of people who give alms to the poor, who fast and sometimes mourn for the world's pain, and sing hymns in open defiance of death, as if dying has somehow lost its terror for them. And here, perhaps most strikingly of all, is a community in which a large percentage of people are single—by choice."
