My fiance's is having problems with his mother, how can I help?

First off, there is NOTHING wrong with praising God. What is wrong is her warped sense of right and wrong. And her warped sense of what God would want. This is your wedding. Do what you will with it. Remind her a psalm is a poem. Be firm, but stand your ground. And always have your fiance's back. Side with him when she starts her crap. Remind him you are starting a whole new life together, and how you two choose to start that should be up to you. And I really like the remembrance candle and poem. great idea.
