How do you reconcile that statement with 1 Corinthians 11:29-32?
29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. 30 For this cause many are weak and sickly among you, and many sleep. 31 For if we would judge* ourselves, we should not be judged. 32 But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
Obviously (from the context) the word judge (
διακρίνω) here means to pass a negative judgment i.e. condemn (
κατακρίνω). Such was the attitude of the prodigal son, he considered himself unworthy to be called a son and for this reason he was accepted as one. Don't look at it logically, it's a paradox:
Some visitors came to the Thebaid one day to visit an old man, bringing one possessed with a devil that he might heal him. When they persistently asked him, the old man said to the devil, "Come out of God's creature." And the devil said to the old man, "I am going to come out, but I am going to ask you a question. Tell me, who are the goats and who are the sheep?" The old man said, "I am one of the goats, but as for the sheep, God alone knows who they are." When he heard this, the devil began to cry out with a loud voice, "Because of your humility, I am driven away!" and he departed at the same hour. - The Desert Fathers
