For one is your Master, even Christ. He repeats a second time the former statement about Christ's office as Master, in order to inform us that the lawful order is, that God alone rule over us, and possess the power and authority of a Father, and that Christ subject all to his doctrine, and have them as disciples; as it is elsewhere said, that Christ is the only head of the whole Church, (Ephesians 1:22) because the whole body ought to be subject to him and obey him.
Neither be ye called masters - That is, leaders, guides, for this is the literal meaning of the word. It refers to those who go before others; who claim, therefore, the right to direct and control others. This was also a title conferred on Jewish teachers.
Neither of these commands forbids us to give proper titles of civil office to men, or to render them the honor belonging to their station, Matthew 22:21; Romans 13:7; 1-Peter 2:17. They prohibit the disciples of Jesus from seeking or receiving mere empty titles, producing distinctions among themselves, implying authority to control the opinions and conduct of others, and claiming that others should acknowledge them to be superior to them.
Neither be ye called masters - Καθηγηται, leaders. God is in all these respects jealous of his honor. To him alone it belongs to guide and lead his Church, as well as to govern and defend it. Jesus is the sole teacher of righteousness. It is he alone, (who is the word, light, and eternal truth), that can illuminate every created mind; and who, as Savior and Redeemer, speaks to every heart by his Spirit.
Though the title of Rabbi, mentioned above, was comparatively recent in the time of our Lord, yet it was in great vogue, as were the others - father and master, mentioned in this and the following verse: some had all three titles, for thus in Bab. Maccoth, fol. 24. It is feigned," says Dr. Lightfoot, "that when King Jehosaphat saw a disciple of the wise men, he rose up out of his throne, and embraced him, and said, אבי אבי רבי רבי מרי מרי, Abbi, Abbi! Rabbi, Rabbi! Mori, Mori! - Father, Father! Rabbi, Rabbi! Master, Master!" Here then are the three titles which, in Matthew 23:7, Matthew 23:8, Matthew 23:10, our blessed Lord condemns; and these were titles that the Jewish doctors greatly affected.
Neither be ye called (k) masters: for one is your Master, [even] Christ.
(k) It seems that the scribes hunted very greatly after such titles, these scribes being the ones whom he called blind guides in (Matthew 23:16).
Neither be ye called masters,.... Or guides and leaders; not but that, the ministers of the word are in a sense such; it is their business to lead and direct souls to Christ, to guide their feet in the way of peace, and to go before them, as examples to them, in word, in conversation, faith, and purity; but then they are to guide them according to the word of God, and not their own dictates; and teach them to observe the rules, and obey the ordinances of Christ, and not what are of their own inventing and prescribing; and to enforce the authority of their great Lord and Master, and not their own; and direct men to a dependence on Christ, as head of the church, who is the one Lord, as his faith is one, and his baptism one also: "for one is your master, even Christ"; which is said before, in Matthew 23:8 but being a matter of so much importance to the honour of Christ, and men being so apt to set up for masters themselves, in opposition to him, or in conjunction with him, or above him, it was necessary to repeat it; for in an authoritative sense he is the one, and only master of the assemblies.
