I'm posting this here vs the religion boards because there's more traffic.
FI and I are pretty active in our church. We know our Pastor and his wife well enough...not hang out outside of church activities but we see them and have friendly conversations. We have been there a year and are currently having pre-counseling sessions with him so we've gotten to know him even more.
Obviously he will be at the rehearsal so we will extend an invite to the RD to him and his wife (even his 3 kids are welcome). We are more than willing to invite them to the wedding also and would love for them to stay. I am just hesitant that they will feel obligated to give us a gift, which we do not want from them. Would you invite them? Also, we do not have their address. Would it be ok to hand him an invite (with a RSVP card including postage)? Or should we just mail it to the church office?
