Besides paying the minister, do you invite him and wife to rehearsal dinner AND also to reception which will be an expensive sit down dinner? What if your parents are members of the church but you haven't been for long time and do not even know the minister? The minister at this church is very new and not even parents really know him or wife. So, minister would be getting let's say $150 plus dinner for two on rehearsal and reception?
Do you send a regular wedding invitation to him & wife?
Do you expect to get a gift from the minister? What kind of gift or price range?
If you were not a member of church and just "using" the church and minister for wedding, do you invite minister and wife to these dinners? And would you expect a gift?
