Just yesterday, I was visiting a friend in the hospital... Eucharistic ministers were offering communion to Catholics and the gal that engaged my friend's room had entered into discussion with her... She was telling the lady about her upbringing, but that she did not practice anymore and that she had not gone to confession in decades... therefore could not receive communion, yada, yada, yada...
Apparently, the offerant was talking to her about sins and that there were only two unforgiveable sins: 1) Killing the Pope and 2) Having more than one abortion....
