Yes, but my previous point is still valid. Remilia isn't inherently cruel, nor is she in any way concerned with or affected by Christian symbols. She finds pleasure in being called an angel and even keeps the crosses of those who tried to exterminate her and Flan as mementos; she even openly mocks gods. She's a peculiar devil.
I think if she finds you praying to God she'd simply give you a smile and call you a wishful fool, just like she pays no mind to the pranks Sakuya plays when she puts weird stuff in Remi's tea.
