1 Timothy 5:20

Them that sin rebuke before all, that others also may fear. — The Apostle here, apparently, is still referring exclusively to that order of presbyters whose more meritorious members he had directed Timothy to honour with a special honour, and towards whose accused members he instructed him how to act. He now passes to the question how to deal with these responsible officers of the Church when they were proved to be notoriously sinning. While, on the one hand, the earnest and devoted men were to be honoured with “a double honour” — while every possible legal precaution was to be taken in the case of those being accused — on the other hand, when proved to be men continuing in sin and error, their punishment must be as marked as in the other case was the reward. The errors and sins of teachers of the faith are far more dangerous than in those who make up the rank and file of congregations, and require a more severe and more public punishment.

It is not improbable that St. Paul was especially alluding here to false teaching — to errors of doctrine on the part of some of the Ephesian presbyters. He seems, in his parting address at Miletus to the elders (presbyters) of this very Ephesian Church, to have foreseen such a grievous falling away in the future among their company — “Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them” (Acts 20:30). Compare also the Epistle to this same Church of Ephesus (Revelation 2:4). As the sin, whatever has been its nature, has been committed by men intrusted with a responsible and public charge, so the rebuke and punishment must also be in public, that the warning may then spread over the whole of the various congregations composing the Church, and thus “others also may fear.”
