First off, the dress is GORGEOUS!!

As for the religion thing, I had a similar problem. I wanted to get married by someone I knew and loved. My neighbor was a minister. I lived next to him for ten years and thought of him as an extention of my family. He had moved two states over but made the trip just to perform the ceremony!

Karen made some excellent points, I agree that I wouldn't put a note in the invitation telling them to keep their noses out of your religion. That might come across in the wrong way. I would call them & respectfully tell them that you honestly would like them to attend your wedding, but would appreciate their religious beliefs be kept to themselves.
