Dale has a great piece in Crisis Magazine on what Chesterton would have made of "gay marriage". Read the whole thing, but just to give you a taste ...
In Heretics, Chesterton almost makes a prophecy of the misuse of the word “gay.” He writes of “the very powerful and very desolate philosophy of Oscar Wilde. It is the carpe diem religion.” Carpe diem means “seize the day,” do whatever you want and don’t think about the consequences, live only for the moment. “But the carpe diem religion is not the religion of happy people, but of very unhappy people.” There is a hopelessness as well as a haplessness to it. When sex is only a momentary pleasure, when it offers nothing beyond itself, it brings no fulfillment. It is literally lifeless. And as Chesterton writes in his book St. Francis of Assisi, the minute sex ceases to be a servant, it becomes a tyrant. This is perhaps the most profound analysis of the problem of homosexuals: they are slaves to sex. They are trying to “pervert the future and unmake the past.” They need to be set free.
And, while you're at it, pack your things and march for sanity in March.
