But since God was going to use Judas's sin,  it was ok to eat with him, unlike other sinners.  Of course,  Judas was a good Catholic at the time of the last supper, he fell later that evening.  So, in summary: Jesus doesn't eat with unrepentant sinners, Judas wasn't an unrepentant sinner; or Jesus ate only with unrepentant sinners when God was planning to use their sins for His purposes.  So how does this affect the serving of the Eucharist?  Is there a method to determine which sinners are going to be used by God, so they can be given a "Judas Waiver?"
