Is the Church Teaching That Homosexual Activity Is Sinful?

Cardinal holerick of luxemburg said he doesn't believe the church's teaching that homosexual activity is sinful. He says, i think we need to change the catechism and catch up with modern sociology and science. Bishop strickland came out an saysaid the same thing a coupleof days ago. So there's just silence from rome. Shameful, you know, that i think.
