I'm not saying Catholics are perfect but quick thing: What sinful activites the members are engaging in in Catholicism are not Church teachings, that's people being sinful. Correct, homosexuals and women should not be priests - they are not allowed to be in Catholicism. Additionally, clergy engaging in sinful activity is a violation of their holy vows, do higher up clergy fail to punish those who fail? Yes, because they are weak.

But in the end the Catholic Church is God's teachings, not the failings of those who are weak and evil. All that matters is that we follow the word of God the best we can, that we root out evil when it is found and we hold leadership accountable when they fail.
