What is proper etiquette about people assisting with the wedding? I want to invite our pastor and wife to the reception. Should I send a formal invite? It's obvious he will be at the ceremony as he is the officiant. Also, what about my soloist and person running the sound system? Should I send them each a formal invite as well? I do not expect gifts from these persons, but I don't want them to be offended if I just say, "oh by the way, you are invited to the reception, too."
Can anyone chime in with their ideas?
