We were married in a Prebyterian church that we both belonged to, by the associate pastor there, and her husband, who is also a Prebyterian minister. At that time, he was the chaplain at a Presbyterian-affiliated college. They are both very close friends of ours. Our boys are good friends and we have vacationed together and have our Buccaneers season tickets together.
3 years ago, he was called to be the minister at the downtown Presbyterian church....the oldest Prebysterian church in our city and a dying one. We started going to church there to support him and the ministry he was trying to build and we love it. We officially joined the church about a year ago.
I don't feel like it's "cheating" on the other church at all. They've got plenty of members there, and lots of $$$ too.
