My doctrine is not mine, but his that sent me. — The answer carries them once more to the words uttered by Him. (Comp. John 5:19; John 5:30.) Then he had again and again referred to the Father who sent Him (John 7:24; John 7:36-38), and claimed as His own work the doing of the Father’s will (John 7:30). In the Capernaum synagogue, in the hearing of some of these Jews, He had declared that all who were taught of God, and heard and learned the lesson, would come to Him (John 6:45). There is, then, no ground for their present wonder. The teaching which is His in relation to them, is not His of original source. He claims to be in His humanity as a messenger, carrying the message of Him that sent Him. He is the Word by whom the mind of God is spoken.
Doctrine represents a word which is frequently used in the Gospels, of our Lord, but only here and in the next verse by Him. It has acquired a definite and concrete meaning not found in the original, which is better rendered by teaching (comp., e.g., Mark 4:2).
