“But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren.”
King James Version (KJV)
23:8-10 The Jewish rabbis were also called father and master, by their several disciples, whom they required, To believe implicitly what they affirmed, without asking any farther reason; To obey implicitly what they enjoined, without seeking farther authority. Our Lord, therefore, by forbidding us either to give or receive the title of rabbi, master, or father, forbids us either to receive any such reverence, or to pay any such to any but God.
Mt 23:8 Be not ye called Rabbi. This prohibits all similar religious titles now. It certainly forbids such as the corresponding title of Doctor of Divinity (D.D.). For one is your Master. Christ is the common teacher of all, and all others are disciples on the same level. The spirit of this command forbids all ecclesiastical titles of honor.
