Take heed to yourselves: If your brother trespasses against you, rebuke him; and if he repents, forgive him.
All Commentaries on Luke 17:3 Go To Luke 17
Theophilus of Antioch
AD 184
As if He says, Offenses must needs come; but it does not follow that you must perish, if only you be on your guard: as it need not that the sheep should perish when the wolf comes, if the shepherd is watching. And since there are great varieties of offenders, (for some are incurable, some are curable,) He therefore adds, If your brother trespass against you, rebuke him.
But some one may well ask, If when I have several times forgiven my brother he again trespass against me, what must I do with him? In answer therefore to this question He adds, And if he trespass against you seven times in a day, and seven times in a day turn again to you, saying, I repent; forgive him.
