In The Benedict Option, Rod Dreher discusses the way Christian teaching on marriage came as a revolutionary alternative to the exploitation of women in the first and second centuries. From page 198:
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.” Chastity—the rightly ordered use of the gift of sexuality—was the greatest distinction setting Christians of the early church apart from the pagan world.
