Matthew 23:9 - Albert Barnes' Notes on the Bible

And call no man your Father ... - This does not, of course, forbid us to apply the term to our real father. Religion requires all proper honor to be shown to Him, Exodus 20:12; Matthew 15:4; Ephesians 6:1-3. But the word “father” also denotes “authority, eminence, superiority, a right to command, and a claim to particular respect.” In this sense it is used here. In this sense it belongs eminently to God, and it is not right to give it to people. Christian brethren are equal. Only God has supreme authority. He only has a right to give laws; to declare doctrines that shall bind the conscience; to punish disobedience. The Jewish teachers affected that title because they seem to have supposed that a teacher formed the man, or gave him real life, and sought, therefore, to be called father. Christ taught them that the source of all life and truth was God, and they ought not to seek or receive a title which properly belongs to him.
