But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such a one no not to eat.
All Commentaries on 1 Corinthians 5:11 Go To 1 Corinthians 5
Tertullian of Carthage
AD 220
I shall not be sorry to meet him, and before anything else to point out to him the force of the law figuratively interpreted, which, in this example of a leper (who was not to be touched, but was rather to be removed from all intercourse with others), prohibited any communication with a person who was defiled with sins, with whom the apostle also forbids us even to eat food.
And are to be excluded from all communication with the brotherhood, in accordance with the letter of the apostle, who says that "with persons of that kind there is to be no taking of food even."
