John Calvin on Hebrews 7:3

3. Without father, etc. I prefer this rendering to that of “unknown father;” for the Apostle meant to express something more emphatic than that the family of Melchisedec was obscure or unknown. Nor does this objection disturb me, that the reality does not correspond with the figure or type, because Christ has a Father in heaven, and had a mother on earth; for the Apostle immediately explains his meaning by adding without descent, or kindred. He then exempts Melchisedec from what is common to others, a descent by birth; by which he means that he is eternal, so that his beginning from men was not to be sought after. It is indeed certain that he descended from parents; but the Apostle does not speak of him here in his private capacity; on the contrary, he sets him forth as a type of Christ. He therefore allows himself to see nothing in him but what Scripture contains. For in treating of things respecting Christ, such reverence ought to be observed as not to know anything but what is written in the Word of the Lord. Now, as the Holy Spirit in mentioning this king, the most illustrious of his age, is wholly silent as to his birth, and makes afterwards no record of his death, is not this the same thing as though eternity was to be ascribed to him? And what was shadowed forth in Melchisedec is really exhibited in Christ. It behooves us then to be satisfied with this moderate view, that while Scripture sets forth to us Melchisedec as one who had never been born and never died, it shows to us as in a mirror, that Christ has neither a beginning nor an end. Some regard what is said of Melchisedec being without father, etc., as meaning that he was so in his office as a king and priest, there being no account of a predecessor or of a successor to him; but this view cannot be taken on account of these words, “without mother, without descent,” etc., Calvin gives the explanation commonly received. — Ed.

But we hence also learn how much reverence and sobriety is required as to the spiritual mysteries of God: for what is not found read in Scripture the Apostle is not only willing to be ignorant of, but also would have us to seek to know. And surely it is not lawful for us to allege anything of Christ from our own thoughts. And Melchisedec is not to be considered here, as they say, in his private capacity, but as a sacred type of Christ; nor ought we to think that it was accidentally or inadvertently omitted that no kindred is ascribed to him, and that nothing is said of his death; but on the contrary, that this was done designedly by the Spirit, in order to give us an idea of one above the common order of men. There seems therefore to be no probability in the conjecture of those who say that Melchisedec was Shem the son of Noah; for if we make him to be some known individual, we destroy this third likeness between Melchisedec and Christ.

Made like, or assimilated, etc. Not as far as what was typified required; for we must always bear in mind that there is but an analogy between the thing signified and the sign; for they make themselves ridiculous who imagine that he came down from heaven, in order that there might be a perfect similarity. It is enough that we see in him the lineaments of Christ, as the form of the living man may be seen in his picture, while yet the man himself is very different from what represents him. Our version “made like,” etc., is objected to by Stuart; and he renders it, “being like,” alleging that the Apostle’s object is to show, not that Melchisedec was “made like” to Christ as a priest, but the contrary, according to Psalm 110:4. But the object here seems to be different: he shows why it is that there is no record of Melchisedec’s office as to its beginning or end; it was that he might be made a fit type to represent the Son of God. — Ed. It seems not to be worth one’s while to refute the delirious notions of those who dream that Christ himself, or the holy Spirit, or an angel, appeared at that time; unless indeed one thought it to be the duty of a right­minded man to dispute with Postillus and such fanatics; for that impostor asserts that he is Melchisedec with no less supercilious folly than those mad spirits of old, mentioned by Jerome, who pretended that they were Christ.

Hebrews Chapter 7:4-10

4. Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.

4. Considerate autem quantus sit hic, cui et decimas dedit de spoliis Abraham patriarcha.

5. And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:

5. Atque ii quidem qui sacerdotium accipiunt, qui scilicet sunt ex filiis Levi, praeceptum habent a populo decimas sumendi juxta legem, hoc est, a fratribus suis licet egressis ex lumbis Abrahae:

6. But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.

6. Cujus autem genus non recensetur ex ipsis, decimas sumpsit ab Abraham, et habentem promissiones benedixit.

7. And without all contradiction the less is blessed of the better.

7. Porro sine controversia quod minus est a potiore benedicitur.

8. And here men that die receive tithes; but there he receiveth them, of whom it is witnessed that he liveth.

8. Atque hic quidem homines qui moriuntur, decimas accipiunt; illic autem is de quo testatum est quod vivat:

9. And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.

9. Et ut ita loquar, in Abraham decimatus est ipse Levi qui decimas solet accipere;

10. For he was yet in the loins of his father, when Melchisedec met him.

10. Nam is adhuc in lumbis patris erat quum occurrerit Abrahae Melchisedec.
