1 Corinthians 4:7, Why Dost Thou Glory?
William MacDonald observed well, “The Corinthians were not forming parties around Paul and Apollos alone, but also around other men who were then in their church. However, out of a sense of Christian courtesy and delicacy, Paul transferred the entire matter to himself and Apollos so that by their example the saints would learn not to have exaggerated opinions of their leaders or to gratify their pride by the formation of parties. He wanted the saints to evaluate everything and everyone by the Scriptures.”
