1 Corinthians 5:1

“It is reported commonly that there is fornication among you, etc.] The apostle having reproved the Corinthians for their schisms and divisions about their ministers, proceeds to charge them with immoralities committed among them, and which were connived at, and took no notice of by them; and particularly a very notorious one, which he here mentions with its aggravated circumstances. It was done among them; not only by one of their citizens, nor merely by one of their hearers, but by one of their members, and so was cognizable by them as a church; for though they had nothing to do with them that were without, yet they were concerned with them that were within: this was a public offence; it…”

“THE INCESTUOUS PERSON AT CORINTH: THE CORINTHIANS REPROVED FOR CONNIVANCE, AND WARNED TO PURGE OUT THE BAD LEAVEN. QUALIFICATION OF HIS FORMER COMMAND AS TO ASSOCIATION WITH SINNERS OF THE WORLD. (Co1 5:1-13) commonly--rather, "actually" [ALFORD]. Absolutely [BENGEL].

“It is reported - Greek It is heard. There is a rumor. That rumor had been brought to Paul, probably by the members of the family of Chloe, 1 Corinthians 1:11. Commonly - Ὅλως Holōs. Everywhere. It is a matter of common fame. It is so public that it cannot be concealed; and so certain that it cannot be denied. This was all offence, he informs us, which even the pagan would not justify or tolerate; and, therefore, the report had spread not only in the churches, but even among the pagan, to the great scandal of religion - When a report obtains such a circulation, it is certainly time to investigate it, and to correct the evil. That there is fornication - See the note at Acts 15:20. The word…”

“Fornication - The original word implies criminal conversation of any kind whatever. His father's wife - While his father was alive. 1 Corinthians 5:2”

“5:1-8 Paul confronts sexual immorality in the church and instructs the Christians to expel a shameless offender from their fellowship. 5:1 sexual immorality: A man was having sex with his stepmother. Such behavior even pagans didn’t do: It violated both the law of Moses (see Lev 18:7-8) and Roman law (Gaius, Institutes 1.63).”
