althought my FI and are both Catholic and we'll be having a full mass for our wedding, we will have many guests who are not Catholic attending. my worry is that other Christians aren't aware that it's not appropriate for them to receive communion in a Catholic church, even though they would at their own church. do people know this rule? i don't want to be rude or hurtfull by saying something in the program? how have you girls dealt with this?!
