I was married in church, as my husband was brought up in the URC/Congregationalist faith and looking back, I think we were somewhat pressured into it by his mother - as we were when we had the eldest baptised. By the time we had the youngest we had begun to see the light and had ceased going to church, so when mum-in-law asked the minister if he'd baptise the child, he said no. I wasn't exactly complaining, as you can imagine.
I know if I had the choices to make again, knowing what I know now, church weddings and baptisms would be out of the question.
I think the thing with churches and all that foof-fah is that it all looks so nice in wedding photos. Thing is, these days there are lots of nice venues with wedding licences, so that's not really an excuse. But churches are cheap by comparison, and although I have little time for christians, I think it's a bit rich using their places just because they look right.
