I was also raised as a Christian, though not a Catholic and I maintain those beliefs today. However, regardless of what is stated by the Pope, the Bible itself states that we must love one another and leave judgments to be made by God himself.

Treating any others with disdain because you are a Christian and they don’t share your views and beliefs truly counteracts the Christian values projected by Jesus himself.
While religious beliefs may be central in your life, I think that it’s also important to consider our environment. Being an American (as I assume you are as well), we should look to our Constitution.

This establishes that the government should not necessarily associate itself or involve itself in any one religion. The fact that gay marriage is illegal is, in fact, a religious issue. By taking a stance on the validity of gay marriage, the government is taking a religious stance.
