What has been the dumbest religious comment/response/statement you have ever heard personally?

Mine happened this week and I'm still shaking my head about it.
My kids and I spent Xmas in New Orleans and spent xmas eve watching the lighting of the bonfires on the Levee.

A coworker asked me about it when I got back and I was explaining the pagan tradition of the bonfires and said, "..before the church turned the winter solstice celebrations into Christmas..."
She cut me off and said, "December 25th has ALWAYS been Christmas"
I said, "No it hasn't, but as I was saying...
She immediately said, "Yes it has, check your calendar."

She is a professional healthcare provider with advanced degrees and her answer was "check your calendar".

I had to walk away because I really wanted to smack her in the back of the head.
