Calvin on Zech 2.10 Discusses the Son’s relationship with the Father

Zechariah 2:9–10 (ESV)

9“Behold, I will shake my hand over them, and they shall become plunder for those who served them. Then you will know that the LORD of hosts has sent me.

10Sing and rejoice, O daughter of Zion, for behold, I come and I will dwell in your midst, declares the LORD.

From Calvin’s commentary on Zechariah 2.10, “

Whenever then Christ announces his own divinity, he takes the name Jehovah; but he also shows, that there is something peculiar and distinct belonging to him as the messenger of the Father. For this reason, and in this respect, he is inferior to the Father; that is, because he is sent as a messenger, and executes what has been entrusted to him. These things do not militate the one against the other, as many unlearned and turbulent men think, who entangle themselves in many vain imaginations, or rather in mere ravings, and say, “How can it be, that there is one eternal God, and yet that Christ, who is distinct from the Father, and is called his angel, is a true God?” So they imagine that the origin of divinity is God the Father, as though the one true God had begotten, and thus produced another God from himself, as by propagation. But these are diabolical figments, by which the unity of the Divine essence is destroyed. Let us then bear in mind what the Prophet teaches here clearly and plainly, — that Christ is Jehovah, the only true God, and yet that he is sent by God as a Mediator.“
