Augustine of Hippo
Catena Aurea · Johannesevangelium 8
Jesus went unto the mount of Olives. And early in the morning he came again into the temple, and all the people came unto him; and he sat down, and taught them. And the Scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst, They say unto him, Master, this woman was taken in adultery, in the very act. Now Moses in the law commanded us, that such should be stoned: but what sayest thou? This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again He stooped down, and wrote on the ground. And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst. When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more. So when they continued asking Him, He lifted Himself up.
(Tract. xxxiii. 5) He did not say, Stone her not, lest He should seem to speak contrary to the law. But God forbid that He should say, Stone her; for He came not to destroy that which He found, but to seek that which was lost. What then did He answer? He that is without sin among you, let him first cast astone at her. This is the voice of justice. Let the sinner be punished, but not by sinners; the law carried into effect, but not by transgressors of the law.
