My fiance and I have gone to some trouble to ensure our civil ceremony remains free of religious themes, both as a result of our own views on the subject and those of the large part of both our families (mixed views, but on the whole, we are non-believers). We have asked both his father and my mother to make a short toast during lunch. I have now found out that my mother intends to incorporate a prayer and offering in her toast. Unfortunately, we are not talking about something like "god bless"... mom actually intends to pray/toast to a pagan goddess. I love my mother beyond measure, but don't share her religious position at all, and become very uncomfortable when the topic arises.
Is it appropriate for me to address the issue, possibly ask her to refrain from any religious references, or should I simply accept the wishes since I did, after all, ask her to make a toast?
It may be best to approach her and inform her of your wishes and needs. She may not know about your views and how firmly you feel about this issue. And, you are a host to those who feel very differently about these issues. So, I agree that it is best to keep the night religious neutral.
