Getting married in a Catholic church and FH is not baptized...

As a pastor's daughter (who is now pagan), I have to say that there are much better ways to let your husband explore other religions, if he is so inclined, than having him participate in a religious ritual on the most important day of your lives as a couple. To be entirely honest, I find that kind of offensive, and I'm wondering if your FH has had any input on what he wants for the ceremony.

As others have said, it's usually a pretty big step. However in most non-denominational Christian churches that I've attended, you could go to church one Sunday and if they are doing a baptism that week they usually won't say no. The one I used to go to here would do baptisms every month or so and the church was held at a school so the school's pool was used for baptisms. They do ask questions such as "Have you accepted Jesus as your lord and savior" before dipping you under water to be baptized. But it sounds like something like that would be best for your FH because it is non-denominational so it doesn't have really any strict rules. For my baptism in a non-denominational church I signed up on the response card that I wanted to get baptized and put it in the collection plate. They then contacted me and I met with the pastor for an hour or so to talk through what it means to get baptized. Then he showed me where the baptism would take place, what to wear, etc. But on the day of my baptism they invited anyone who maybe felt the call to accept Jesus as Lord that day to come up. Occasionally people would, they'd be in their full out church clothes and then be completely submerged under water, but it just showed how much they wanted to get baptized. There really was no certificate that I got or anything though. So I'd ask your church if they would accept something like that.

Actually, you should probably just get in touch with the priest of that specific church. I've seen inter-religiuos ceremonies, specifically between Catholic & Muslim. He would only need to be super respectul during the ceremony. No baptism necessary.

BUT, talk to your priest first, explain the situation, this is only for YOU not him.

Hope it helps.
