”In her walk with Jesus she believes she is told to submit to me her husband. It is something God requires of her not me. So i agree that submission is a voluntary act.”

Mark
All this is saying is that you are not commanding her to submit, but rather God is commanding her to submit. Therefore, you can fall back on saying God said so. This does not describe voluntary anything. This is still you requiring her to submit. In your eyes she is not a good Christian woman unless she submits to your desires, requests, etc. as long as they are not sin.
