I did post this in another forum, but I didn't know this one existed (I'm new to the message boards) so I figured I'd post it in here as well so I get your input as well.
My fiance and I (still so WEIRD saying that lol) are both Catholic. We even went to same Catholic school as kids and while we aren't ultra-religious we know it'd mean a lot to my parents and grandma that we get married in a church. To be honest it isn't something either of us are opposed to, we just hadn't thought we would be able to.
And here's why; while neither of us has ever been married before I do have a six year old son from a previous relationship and by the time we get married Little Man will be 8. I know that sex before marriage and children as a result are a big "no no" for the church, so I didn't think we'd be able to get married in one. I don't want to start calling churches and priests asking questions if we're just going to be denied in the end.
Any insight would be greatly appreciated 
While, as I said, we aren't ultra-religious, we do make it a point to try and get to church once a week at least, but work schedules don't always allow that. Also, my faith is important to me, especially after I had my son, and it's continued to be important throughout the past year and a half as between my fiance and I we lost four very important people in our lives. I guess my point is that it wouldn't just be to please my parents/grandma for us to get married in a church, but something we've discussed as well.
