John Chrysostom
Catena Aurea · Lukasevangelium 6
Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven: Give, and it shall be given unto you: good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.
You will not easily find any one, whether a father of a family or an inhabitant of the cloister, free from this error. But these are the wiles of the tempter. For he who severely sifts the fault of others, will never obtain acquittal for his own. Hence it follows, And ye shall not be judged. For as the merciful and meek man dispels the rage of sinners, so the harsh and cruel adds to his own crimes.
