John Calvin on the Deity of Jesus in the Old Testament (Part 2 of 2)

"The same thing is intimated by Hosea, who, after mentioning the wrestling of Jacob with the angel, says, 'Even the Lord God of hosts; the Lord is his memorial' (Hos 12:5).  Servetus again insinuates that God personated an angel; as if the prophet did not confirm what had been said by Moses, 'Wherefore is it that thou dost ask after my name?' (Gen 32:29, 30).  And the confession of the holy patriarch sufficiently declares that he was not a created angel, but one in whom the fullness of the Godhead dwelled, when he says, 'I have seen God face to face.'  Hence also Paul's statement, that Christ led the people in the wilderness (1 Cor 10:4. See also Calvin on Acts 7:30, and infra, c. 14 s. 9).  Although the time of humiliation had not yet arrived, the eternal Word exhibited a type of the office which he was to fulfill.  Again, if Zech 1:9, etc., and Zech 2:3, etc., be candidly considered, it will be seen that the angel is immediately after declared to be the Lord of Hosts, and that supreme power is ascribed to him.  I omit numberless passages in which our faith rests secure, though they may not have much weight with the Jews.  For when it is said in Isaiah, 'Lo, this is our God; we have waited for him and he will save us; this is the Lord: we have waited for him, we will be glad and rejoice in his salvation; (Isa 25:9), even the blind may see the the God referred to is he who again rises up for the deliverance of his people.  And the emphatic description, twice repeated, precludes the idea that reference is made to any other than to Christ.  Still clearer and stronger is the passage of Malachi, in which a promise is made that the messenger who was then expected would come to his own temple (Mal 3:1).  The temple certainly was dedicated to almighty God only, and yet the prophet claims it for Christ.  Hence it follows, that he is the God who was always worshiped by the Jews" (John Calvin, Institutes of the Christian Religion).
