Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 23
Woe unto you, Scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous, And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets. Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
The character of the parents is a witness to the sons; if the father be good and the mother bad, or the reverse, the children may follow sometimes one, sometimes the other. But when both are the same, it very rarely happens that bad sons spring of good parents, or the reverse, though it be so sometimes. This is as a man is sometimes born out of the rule of nature, having six fingers or no eyes.
