Just for the record, before I met my husband, I dated a wonderful Christian man, and we had such a disagreement. We met in a reformed Baptist church, but I was studying paedo baptism at the time. It wasn't too long before I made the switch, and he couldn't agree. I knew I wasn't going to change my mind, so we broke it off.
Though I highly respect the views of my credo baptist brothers and sisters, if I had married (and we were discussing it seroiusly) I would have always felt like I was denying my convictions, and I'm sure it would have caused trouble later on.
It shouldn't. If a paedo woman marries a credo man I would certainly expect them to discuss the issue. In the end the wife is to submit to her husband on the issue and not allow it to become a point of contention. If she continues to fight against it then she is sinning. If both feel strongly about the issue before marriage than courtship/marriage should never take place. Unfortunately many are blinded by love and don't count the cost in this area.
