I'm trying to evangelize to a man who is on his second marriage. I know that marriages between non-Catholics are generally valid, so if he converts, he and his wife will have to live as brother and sister, unless he can get an annulment. But suppose he can't. How can I, especially as someone who chose celibacy before converting, tell him he has to give up sex forever? That's not going to make the faith appealing to him.
I don't pretend to understand why some people would rather go to Hell than give up sex, so I'm stumped on this one.** (I think people who refuse to convert because of a cherished sin forfeit invincible ignorance.)**
I think you could be wrong about that. Often it's because they feel so strongly about the issue that they think that the Church must not be the one true faith, after all.
I'm not sure it would be your place to tell this person anything about how to conduct his sex life. He will discover it on his own as he explores the faith and it will probably be addressed by a priest in RCIA if he decided to go that route.
