Q: Some say that since the sexual revolution of the 1960s, the Church has been challenged in a way it has never been before to defend its teachings on sexuality. In what way? Father Percy: Most cultural commentators would agree that the sexual revolution began in the 1920s. In fact, G.K. Chesterton said of the sexual revolution that there was "more madness coming out of Manhattan than there was out of Moscow!" He perceived that the next heresy the Church would have to deal with would be of a sexual nature. We, now living in the 21st century, surely have no problems in recognizing the immense challenge before us. But "today" is our starting point and not "yesterday" or "tomorrow" -- what might have been or what might be. And the starting point -- or so it seems to me -- is this wonderfully intriguing and inviting teaching called the theology of the body.
