Mark 12:35-37 David’s Son And Lord.
Jesus just finished answering a scribe as to which command was the greatest, and in the process what it meant to be in the kingdom of God. For that scribe Jesus was but a teacher, not Messiah Yeshua, who was anointed in part to take away the sins of his people. This is the only way into the kingdom, keeping the commands is but a response of our love to his. Jesus here seeks to press this point concerning his personage. If he was but a mere man, albeit a good teacher, then his acceptance of the testimony of the Father that he was in fact his Son was either a lie or he was delusional (1:11), and so was his claim to be able to forgive sins (2:5-10). His anointing as the Christ, and his repeated claims to be such focused on his primary purpose. However, this invariably had to lead to one question – where did it ever say that the Messiah would be both God and man?
It is to this question that Jesus in fact appeals to the Hebrew scriptures, and the prophetic words of David himself (v. 35 Cf. Mt. 22:41-46; Lk. 20:41-44). It was acknowledged by all that the Messiah would be a son of David, but David also calls him Lord or Master – a position reserved for God alone. Not only this, but in David’s testimony we have a Trinitarian confession, for David spoke by the Spirit of the Father, the LORD of the covenant, and of his Lord, the mediator of that covenant (v. 36; II Sam. 23:2; Ps. 110:1). Jesus made reference to the two preceding passages, for a double witness. Therefore, Jesus asks the very simple question – how can he be both David’s son and his Lord? “The common people heard him gladly” (v. 37), because his teaching was clear and unambiguous. If one accepts the authority of holy scripture, then the only conclusion that one can come to is that he is both.
