We are having a full Catholic Mass for our wedding coming up. We have a priest which will be the "celebrant" for the mass but we also have a family friend who is a Catholic Deacon and will be assisting in Mass. To make things even more complicated we have ANOTHER family friend who is an Episcopal priest who will also be assisting. My question is - how do I list the Episcopal priest and Catholic Deacon in the program? I think according to the Church they are not celebrants....I don't know the word to use. Thanks for any suggestions!!!
