OK, so what’s He saying here? What’s His point? He is admonishing those who would raise themselves up as “holier than thou,” are spiritually prideful, and boasters. He is saying that we are not to put any man, including ourselves, including the Pope, above God, simple as that. He is not saying that we are not to literally ever call a man father or rabbi or teacher or master; to believe otherwise is to call Him a liar because He Himself calls people father, in both the physical and spiritual sense (in that same chapter, even, in Mark 7, Mark 10, Mark 13, Luke 6, etc.) and doesn’t admonish those who refer to “our father David” as they greet Him during His triumphant entry into Jerusalem. The four evangelists speak the same way, Christ’s Mother speaks the same way, as does Paul who refers numerous times to our “father Abraham.”
Mark 11:9-10
And they that went before, and they that followed, cried, saying, Hosanna; Blessed is he that cometh in the name of the Lord: Blessed be the kingdom of our father David, that cometh in the name of the Lord: Hosanna in the highest.
Matthew 23:29-31
[Jesus speaking in same chapter as the "Don’t call men ‘fathers’ verse] Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous, And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets. Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets. Fill ye up then the measure of your fathers.
