4 “O God, in Your name make me safe, and in Your virtue judge me”. Let the Church say this, hiding amid the Ziphites. Let the Christian body say this, keeping secret the good of its morals, expecting in secret the reward of its merits, let it say this: “In Your virtue judge me.” You have come, O Christ, humble You have appeared, despised You have been, scourged hast been, crucified hast been, slain hast been; but, on the third day hast risen, on the fortieth day into Heaven hast ascended: You sit at the right hand of the Father, and no one sees: Your Spirit thence You have sent, which men that were worthy have received; fulfilled with Your love, the praise of that very humility of Yours throughout the world and nations they have preached: Your name I see to excel among mankind, but nevertheless as weak to us have You been preached.
For not even did that Teacher of the Gentiles say, that among us he knew anything, “Save Christ Jesus, and Him crucified;” in order that of Him we might choose the reproach, rather than the glory of the flourishing Ziphites. Nevertheless, of Him he says what? “Although He died of weakness, yet He lives of the power of God.” He came then that He might die of weakness, He is to come that He may judge in the power of God: but through the weakness of the Cross His name has been illustrious.
Whosoever shall not have believed upon the name made illustrious through weakness, shall stand in awe at the Judge, when He shall have come in power. But, lest He that once was weak, when He shall have come strong, with that fan send us to the left hand; may He “save us in His name, and judge us in His virtue.” For who so rash as to have desired this, as to say to God, for instance “Judge me”? Is it not wont to be said to men for a curse, “God judge you”? So evidently it is a curse, if He judge you in His virtue; and shall not have saved you in His name: but when in name precedent He shall have saved you, to your health in virtue consequent He shall judge.
Be thou without care: that judgment shall not to you be punishment, but dividing. For in a certain Psalm thus is said: “Judge me, O God, and divide my cause from the nation unholy.”...
