Matthew 23:10

“Neither be ye called masters, etc.] 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…”

“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.

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.…”

“23:10 Teacher: This title denotes the function and office of leading others into knowledge about God. Jesus, not the scribes and Pharisees, is the teacher of God’s will (5:17).”
