1. The Catholic Church has every right to speak out about marriage because Holy Matrimony is one of the Sacraments of the Catholic Church, and because the government has granted ministers of the Catholic Church legal status in marrying couples. If the government re-defines marriage (which has ALWAYS meant a heterosexual union that includes protection for the children ensuing from the relationships), the government can demand that Catholic ministers extend the Sacrament of Holy Matrimony to same-gender couples - in other words, the government can demand that Catholic people commit a very serious sin. This is a violation of our first amendment right to religious freedom (yes, Catholics are supposed to get that right, too).
2. The Catholic Church has every right to speak out against abortion because innocent, helpless human beings are slaughtered through abortion, and the Church is morally obligated to defend the defenseless.
3. Child molesters hiding among our clergy should be prosecuted, convicted and punished for their grimes, but that's the role of the government, not the Church. It's ridiculous how short the sentences are for child molesters in this country, and the whole statue of limitations that prevents many of these criminals from being charged should be abolished. I'd like to see that changed, too, but it changes with the LAW, not the Church. What are you doing to get the LAWS changed so that child molesters serve longer sentences and don't escape under statutes of limitations?
4. As for forgiving criminals, the Church is supposed to forgive everybody, including criminals.
5. Fixing corruption is an ongoing process. It takes time, but I think the US bishops have made a lot of ground in the last 10 years. What would you do differently?
