Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 7
Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the Law and the Prophets.
Otherwise; He had above commanded us in order to sanctify our prayers that men should not judge those who sin against them. Then breaking the thread of his discourse He had introduced various other matters, wherefore now when He returns to the command with which He had begun, He says, All things whatsoever ye would, &c. That is; I not only command that ye judge not, but All things whatsoever ye would that men should do unto you, do ye unto them; and then you will be able to pray so as to obtain.
