1 Corinthians 3:3-5

For as long as [there are] envying and jealousy and wrangling and factions among you, are you not unspiritual and of the flesh, behaving yourselves after a human standard and like mere (unchanged) men? For when one says, I belong to Paul, and another, I belong to Apollos, are you not [proving yourselves] ordinary (unchanged) men? What then is Apollos? What is Paul? Ministering servants [not heads of parties] through whom you believed, even as the Lord appointed to each his task: 1 Corinthians 3:3-5
