Hi maryelise -
I just wanted to say a few things about not receiving communion.
I went to church for YEARS without receiving communion. I was contracepting. And I didn’t feel the least bit bad about it.
So, no communion for me.
Your friend should in no way feel she is somehow being singled out. Probably most of the people who are ACTUALLY receiving Communion shouldn’t be anyway.

If she’d like, she can still approach the priest, cross her arms, and she will receive a blessing. No one even really knows that just went on except her and the priest.
Even now, I probably only receive communion half the time. We’re not contracepting, but I’ll miss mass and then it takes me like two weeks to get to confession.
So, there you have it.
I happen to think that her going to church, even without physically being able to receive the body of the Lord, might be even MORE pleasing to Him. I mean, really, how much does that show she WANTS to be with Him than by allowing herself to be in His presence without illicitly receiving His body.
And again, as everyone else said, all of this might be moot in that your friends can receive communion anyway, but I just thought I’d share.
Best wishes to you and your friends!!
