Matthew 23:9 - Ellicott's Commentary On The Whole Bible

Call no man your father. — This also, under its Hebrew form of Abba, was one of the titles in which the scribes delighted. In its true use it embodied the thought that the relation of scholars and teachers was filial on the one side, paternal on the other; but precisely because it expressed so noble an idea was its merely conventional use full of danger. The history of the ecclesiastical titles of Christendom offers in this respect a singular parallel to that of the titles of Judaism. In Abbot (derived from Abba=Father), in Papa and Pope (which have risen from their application to every priest, till they culminate in the Pontifex summus of the Church of Home), in our “Father in God,” as applied to Bishops, we find examples of the use of like language, liable to the same abuse. It would, of course, be a slavish literalism to see in our Lord’s words an absolute prohibition of these and like words in ecclesiastical or civil life. What was meant was to warn men against so recognising, in any case, the fatherhood of men as to forget the Fatherhood of God. Even the teacher and apostle, who is a father to others, needs to remember that he is as a “little child” in the relation to God. (Comp. St. Paul’s claim in 1 Corinthians 4:15.)
