Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
Think not that I am come to destroy the Law, or the Prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
If even an honourable man blushes to be found in a falsehood, and a wise man lets not fall empty any word he has once spoken, how could it be that the words of heaven should fall to the ground empty? Hence He concludes, Whoso shall break the least of these commandments, &c. And, I suppose, the Lord goes on to reply Himself to the question, Which are the least commandments? Namely, these which I am now about to speak.
