I have never in 27 years refused anyone communion, Dennis. In any new parish I was appointed to, I'd watch who wasn't going to communion. After a while I'd approach them privately and say to them that I didn't know why they weren't going and didn't want to know either, but let them know they were welcome. That generally opened up the door for them to discuss their situation and I could take it from there. The important thing for me was to open the door.

As I say, I was more overt about it after AL. One Eucharistic minister resigned saying that they couldn't in conscience give communion to a divorced/remarried person. That person now attends another parish. 

One man had been with the same woman for over forty years. It was his second marriage. He took full responsibility for the failure of the first (he was a teenager and said he was immature. He placed no blame on his first wife.) He hadn't received communion in all that time. Parishioners are overjoyed for this very decent man.
