I have heard a coincidence better called a minor miracle (are any miracles minor

?) where God chooses to remain anonymous.
Go very slowly and carefully with how you proceed. Pray for guidance and discuss the situation with those involved before you "out" anybody. These fellow church members may not be comfortable with anyone in their home church knowing about their lifestyle. That can get ugly quick. All it takes is one small slip of the tongue.
Pray, pray, pray, and then pray some more. Let your wife move at her own speed. Show her your beliefs, and why you feel being a nudist is beneficial and not non-scriptural, but DON'T force her. She may come around to see the truth of the situation, as my wife did, or she may not, but it has to be her choice.
God Bless
