For there must be also heresies among you, that they who are approved may be made manifest among you.
All Commentaries on 1 Corinthians 11:19 Go To 1 Corinthians 11
John Chrysostom
AD 407
In speaking here of factions, Paul did not have doctrinal heresies in mind, though it would apply to them as well. Christ himself said that occasions of stumbling would have to come (Mt :). He did not thereby destroy man’s free will or decree any necessity or compulsion over human life, but he foretold what would be the inevitable result of the evil in the human mind. Divisions did not come about because Christ foretold them; rather he foretold them because they were inevitable.
