I'm a Christian, my finacee is an atheist. Both of us are quite strong in our faith (or lack there of). Until recently, I was planning on becoming a pastor (realized that wasn't the path for me, faith is still as strong as ever, but that's a totally different story).
My fiancee and I are already planning on having two weddings. One will be the traditional(ish) church wedding with a traditional(ish) reception. The other will be at the science fiction convention we both go to. The church wedding is more for me, while the convention wedding is more for him (though, really, I would say it's for him and me equally). Given that we're already planning on doing two weddings, how much do I have to cater to his atheism at the church wedding? My main issue is scripture. The vows are not very negotiable, since there are certain things that have to be said for it to count as a United Methodist wedding. I don't really want to read something like 1 Corinthians 13, which is a scripture he would "agree" with. I'd rather something like the end of Romans 8, or the conversation between Ruth and Naomi, but those are both heavily religious scriptures, as opposed to expressing a more generic sentiment like "hey, love's a great thing!"
