'When it comes to sex, one cannot leave out marriage. The no to sex outside marriage seems arbitary and cruel apart from the Creator's yes to sex within marriage. Indeed, one can say that in Christianity's vocabulary the only real sex is the sex that happens within marriage; the faux sex that goes on outside marriage is not really sex at all. The physical coming together that happens between two people who are not married is a distorted imitation of sex, as Walt Disney's Wilderness Lodge Resort is only a simulation of real wilderness. The danger is that when we spend too much time in the simulations, we lose the capacity to distinguish between the ersatz and the real.'
