I am Catholic and FI is Protestant (from a small evangelical denomination). We are having the Rite of Marriage Outside of Mass, and the officiant will be a deacon who is a personal friend. We are having FI's family pastor say a prayer during the ceremony, just a small thing-- FI's family love him, but neither FI nor I are crazy about him, and FI has mostly been coming to Mass with me, although we occasionally go to his church's service. We wanted to involve the pastor as a nod to FI's faith tradition and to his family.
So here's the issue: on the program, I have no idea what to call the role the pastor is playing. That is, the deacon is identified as "Deacon [Name], Officiant," the lectors are labeled as "lectors," the cantor is labeled "cantor," etc. What is an appropriate and respectful role name to give the Protestant pastor who is just saying a prayer? "Rev. [Name], ???" The deacon has said that we could use the phrase "Assisting Minister," but that seems a little grandiose for the level of involvement we're actually giving him, and I almost worry that it would call attention to how LITTLE he's doing in the ceremony. Since the deacon is coming in from out of state, using an adjective like "Visiting" or "Guest" for the local Protestant pastor would also feel a little odd, but might still be appropriate. Any ideas?
