My pastor when I was going through confirmation made me sit down and have a serious discussion about pre-marital sex, and how it was wrong. Including asking me if I ever thought of having sex.
I looked him dead in the eye and said "seeing as we don't have confession, I don't see how it's any of your business.
"
Then I promptly told my parents that I thought it was particularly creepy that my pastor felt the need to sit down with me (a 14 year old girl that was more interested in school than boys) and tell me something I ALREADY KNEW.
That guy was such a creeper.
About the topic at hand, the only thing I've ever heard my church as a whole putting forward to the congregation to consider is that homosexuals are, indeed, actual people, and should therefore be treated as such. And that it was mean spirited and sinful to treat them any differently than we would any straight person. Whether that applies to marriage, not sure.
