Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 7
Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
But that not even thus should Christians correct Christians is shewn by that expression, Judge not. But if they do not thus correct, shall they therefore obtain forgiveness of their sins, because it is said, and ye shall not be judged? For who obtains forgiveness of a former sin, by not adding another thereto? This we have said, desiring to shew that this is not here spoken concerning not judging our neighbour who shall sin against God, but who may sin against ourselves. For whoso does not judge his neighbour who has sinned against him, him shall not God judge for his sin, but will forgive him his debt even as he forgave.
