I am Catholic and my Future Hubby is in RCIA and we will be having a full Mass for the Ceremony.  His family however do not practice any religion really.  For our mass, my sisters will be doing readings and my niece and nephew will be the flower girl and ring bearer.  Is there any way I can get his family involved as well?  I was thinking his mom and dad could present the gifts, but is this allowed if they aren't Catholic?  I want to involve them, but don't want to offend the Church either.
Also, how do you do communion?  My whole side of the church will be receiving communion, but I don't want his side to get confused and take communion when they shouldn't!!
Any advice is appreciated!!!!
