Earlier today I read a news story in which the administrator of a Catholic school, a nun, was forced to abandon her post after parents and students responded in outrage to her firing a swim coach involved in a gay marriage. A conservative commentator, Rod Dreher, noted that Catholic culture itself seemed to be increasingly accepting of homosexuality. The Catholic church has considerable staying power; it has weathered the rise and fall of empires and seen radical cultural shifts in its history. Taking for granted the fact that the Catholic Church will still be keeping the faith a hundred or two hundred years from now, then, I wonder what the official doctrine on homosexuality will be. Will the church as an institution attempt to hold the line, becoming more sternly orthodox and possibly shrinking in number and popular influence, or will some papal bull or encyclical or series thereof find room for evolution on this matter in the church canons? What examples are there of radical shifts in Catholic doctrine through the years? Does anything approach a possible shift to the Church's policy on homosexuality as sin and same-sex marriage as invalid?
