Quote #10

"For the early Church," Langdon explained in a soft voice, "mankind's use of sex to commune directly with God posed a serious threat to the Catholic power base. It left the Church out of the loop, undermining their self-proclaimed status as the sole conduit to God. For obvious reasons, they worked hard to demonize sex and recast it as a disgusting and sinful act. Other major religions did the same." (74.35)

That's some kind of power, to be able to completely change an entire society's views on sex. Obviously it took some time, but that's a pretty impressive feat. Do you think sex as a religious experience would really have threatened their power base that much?
