Homosexuality does not just go against Catholic teaching. If one reads the St. James, New International Version (NIV) or the Vulgate (Catholic) versions of the Bible, homosexual behavior is condemned by God. This is both in the Old and New Testament
The liberal press is trying to make this a "Catholic thing"--this is just not true.
Homosexuality has been condemned by Christians since the beginning. In this we followed the Jews, who regarded this practice as pagan. I think that pagan temples had both male and female prostitutes.
