Wishing to be fair, I went over Father Martin's YouTube talk and realize that, although Father Martin did talk about the doctrine that gay persons must remain celibate, not being "received" by the gay community. He never said that this then "disqualifies" it as doctrine; Father Martin is too smart for such a statement (I think). He did however, amid much circumlocution, suggest that this situation was analogous to the church's Humanae Vitae encyclical which has been largely been ignored by much of the faithful (not all). He then says that the gay community should perhaps speak with their bishop. I get the impression that he might be suggesting that the gay community may similarly ignore this teaching as many have rejected Humanae Vitae and the teaching of no sex outside of marriage. My comment: although these teachings are ignored, they are still "on the books."
I make this new comment because I want to be fair to Fr. Martin - bearing false witness is a serious offence.
