30. Therefore, seeing he was a prophet He showeth, by two reasons, that it is no marvel if David do speak of things that should come to pass long after his time; the former is, because he was a prophet. And we know that things to come, and such as are removed far from the knowledge of men, are revealed unto the prophets. Therefore, it were wickedness to measure their speeches according to the common manner and order which we use in measuring the speeches of other men, forasmuch as they go beyond the long courses of years, having the Spirit for their director. Whereupon they are also called seers; because being placed, as it were, upon an high tower, (121) they see those things which, by reason of great distance, are hidden from other men. Another reason is, because Christ was promised to him peculiarly. This maxim was so common amongst the Jews, that they had ever now and then the son of David in their mouth, so often as there was any mention made of Christ. They be no such arguments, I confess, as do necessarily prove that this prophecy is to be expounded of Christ; neither was that Peter’s intent and purpose; but first he meant to prevent the contrary objection, whence David had such skill to foretell a thing which was unknown. Therefore he saith, That he knew Christ, both by prophetical revelation, and also by singular promise. Furthermore, this principle was of great (Romans 10:4) force amongst the better-minded sort which Paul setteth down, that Christ is the end of the law. (122) No man, therefore, did doubt of this, but that this was the mark whereat all the prophets did aim, to lead the godly unto Christ as it were by the hand. Therefore, what notable or extraordinary thing soever they did utter, the Jews were commonly persuaded that it did agree with Christ. Furthermore, we must note, that Peter doth reason soundly, when he gathered that David was not ignorant of that which was the chiefest point of all revelations.
He had sworn with an oath God swore not only to the end he might make David believe his promise, but also that the thing promised might be had in greater estimation. And to this end, in my judgment, it is here repeated, that the Jews may think with themselves of what great weight the promise was, which God did make so notable (and so famous.) The same admonition is profitable for us also. For we need not to doubt of this, but that the Lord meant to set forth the excellency of the covenant by putting in a solemn oath. In the mean season, this is also a fit remedy for the infirmity of our faith, that the sacred name of God is set forth unto us, (123) that his words may carry the greater credit. These words, “according to the flesh,” do declare that there was some more noble thing in Christ than the flesh. Therefore Christ did so come of the seed of David as he was man, that he doth nevertheless, retain his divinity; and so the distinction between the two natures is plainly expressed; when as Christ is called the Son of God, according to his eternal essence, in like sort as he is called the seed of David according to the flesh.
