Such ceremonies are, for me personally, traditional. Hence a church is the best place.

I thoroughly enjoyed a family wedding the other year. Lots of King James style thee and thou from the vicar. I had heard of all the hymns (mostly written by my near neighbour Charles Wesley) my wife helped the locals with the bell ringing and the organist had heard of Bach.

Conversely, a christening I went to last year had electric guitar, drums, bass, flashing lights, a vicar called Steve in a Hawiian shirt, various members of the congregation getting the microphone crying saying "thank you Jesus for being wonderful" and the words of the "hymns" seemed to consist of "he is great, live for him" ad nauseum as a repeating chant. In case you didn't notice the subliminal message, the words were on the wall in a PowerPoint presentation.

The former was a joy, the latter a fair shot at Dante's Inferno.

A humanist ceremony? About as relevant as the born again idiots who love their Lord but seem disdainful of tradition.

My first wedding was in a church. Loved the whole experience. My second wedding was in a hotel. Loved the whole experience. For the religious friends and family, it was sad that the church they love prevented them from enjoying a Church wedding, and we would have liked it too. They had no ceremonies to help pay the bills that day, I am reliably informed. Their loss. If they think people use churches for traditional ceremony due to having an imaginary friend, then this Dawkins that God botherers are fascinated about seems to have a point in the title God Delusion.
