‘For when one says, “I am of Paul.” And another, “I am of Apollos.' Are you not men?'
Instead of concentrating on learning about and knowing Christ, and loving one another, and pleasing God, and dying to themselves, they have taken sides supporting one or another particular approach to things, and certain particular men, possibly even using their spiritual gifts to that end, and have caused dissension on the basis of it (Paul and Apollos are only being cited as examples - 1 Corinthians 4:6). ‘Are you not men?' That is, are you not behaving like ‘natural' men (1 Corinthians 2:14)? Are you not behaving like mere men who have had no spiritual illumination.
“I am of Paul.” And another, “I am of Apollos”. The names of Paul and Apollos are given as examples to represent all who preach in Christ's name (1 Corinthians 4:6). The point is that to lay too much emphasis on any man of God is wrong. They do not belong to Paul. They do not belong to Apollos. All are servants of the One on Whom attention should be set, that is, Christ. They belong to Christ (1 Corinthians 3:23).
