I'm having Roman Catholic service, not mass since my FI is not baptized. I know I will have a reader for the first and second reading as well as the prayer of the faithful. I will probably need 3 ushers as well. Is there anyone else I am forgetting? Who did you use for your ceremony? I want to make sure I ask everyone so they have enough time to come in for the rehearsal (most of my extended family is from out of town).
