John Barry's blog has the full q and a with exorcist Gabriel Amorth but I thought this part was especially interesting.
Question: If two gay people love each other why can they can not marry?Can't really add much to that, can I?
Father Amorth: Dear children, God has instituted marriage between a man and a woman. God created men and women complementary, but here you go against the most basic principles of reason. It's true that we are in a world so confused! At the time I was flabbergasted when, on the occasion of the referendum on divorce, I saw many Catholics vote for divorce. At that time I broke the friendship with my dear friend that maybe some of you have heard of -Carlo Carretto, Monaco. He publicly said: "I vote in favor of divorce." In my area in Emilia all the advocates of divorce went around with the speech of Carlo Carretto. Many Catholics voted for divorce, then, even worse, many Catholics voted for abortion. Jesus said, "What God has joined together let no man put asunder." Abortion is against the 5th commandment "Thou shalt not kill." I have seen many Catholics vote for abortion, and those who practice abortion are murderers who have a patron: King Herod, the author of the Massacre of the Innocents. Doctors should cure the disease and not kill. But you say it's crazy we live in a world so upset that if today a referendum were held on euthanasia it could be passed. If a referendum were held on adoption of children by homosexual couples it could pass. It is 'a shattered world , so here it is essential that a Christian who wants to live as a Christian, must be different from the others. Christians must stand up for their beliefs and not be shy.
