From Dreher's Sex After Christianity

The entire essay is here. 

It is nearly impossible for contemporary Americans to grasp why sex was a central concern of early Christianity. Sarah Ruden, the Yale-trained classics translator, explains the culture into which Christianity appeared in her 2010 book Paul Among The People. Ruden contends that it’s profoundly ignorant to think of the Apostle Paul as a dour proto-Puritan descending upon happy-go-lucky pagan hippies, ordering them to stop having fun.

In fact, Paul’s teachings on sexual purity and marriage were adopted as liberating in the pornographic, sexually exploitive Greco-Roman culture of the time—exploitive especially of slaves and women, whose value to pagan males lay chiefly in their ability to produce children and provide sexual pleasure. Christianity, as articulated by Paul, worked a cultural revolution, restraining and channeling male eros, elevating the status of both women and of the human body, and infusing marriage—and marital sexuality—with love.

Christian marriage, Ruden writes, was “as different from anything before or since as the command to turn the other cheek.” The point is not that Christianity was only, or primarily, about redefining and revaluing sexuality, but that within a Christian anthropology sex takes on a new and different meaning, one that mandated a radical change of behavior and cultural norms. In Christianity, what people do with their sexuality cannot be separated from what the human person is.

It would be absurd to claim that Christian civilization ever achieved a golden age of social harmony and sexual bliss. It is easy to find eras in Christian history when church authorities were obsessed with sexual purity. But as Rieff recognizes, Christianity did establish a way to harness the sexual instinct, embed it within a community, and direct it in positive ways.

What makes our own era different from the past, says Rieff, is that we have ceased to believe in the Christian cultural framework, yet we have made it impossible to believe in any other that does what culture must do: restrain individual passions and channel them creatively toward communal purposes.
