Yet in receiving it, take it into consideration, investigate, and only after investigation pronounce judgment and impose penalty. The Apostle's words point to strict investigation.
Do not cut off at once, but investigate everything with great exactness. When you have clearly learned the truth, exact punishment strictly, so that others may also be admonished.
For just as it is harmful to condemn thoughtlessly, so not to punish those who have clearly sinned is to give others a path to do the same.
He says, rebuke, showing that one must act not somehow casually, but with strictness. In this way others too will fear.
Therefore the Apostle wants all to have fear before the bishop, and he sets him over all."
"When he began speaking of judgment, he added, 'I charge you before God.'" He utters a fearful admonition. It is as though he said: "I call God, His Son, and His servants as witnesses that I have commanded you. Behold, before all I command you."
He frightens Timothy and calls the Father and the Son as witnesses to what has been said. Thus, on the coming day, if anything contrary to duty should be done, he will stand justified before Him. That is, he removes every responsibility from himself (Chrysostom).
According to Theophylact, the Apostle speaks to Timothy as though saying: "Be even toward those whose case is being judged, so that no decision may occur without discernment, that is, no prejudgment.
Do nothing by inclination, that is, by partiality, leaning to one side. Let no one preoccupy you or draw you to himself beforehand, so that for this reason alone he disposes you to pronounce judgment and make a decision."
