Hebrews 7:2

Now among the Greeks, Minos the king of nine years’ reign, and familiar friend of Zeus, is celebrated in song; they having heard how once God conversed with Moses, “as one speaking with his friend.” Moses, then, was a sage, king, legislator. But our Saviour surpasses all human nature. He is so lovely, as to be alone loved by us, whose hearts are set on the true beauty, for “He was the true light.” He is shown to be a King, as such hailed by unsophisticated children and by the unbelieving and ignorant Jews, and heralded by the prophets. So rich is He, that He despised the whole earth, and the gold above and beneath it, with all glory, when given to Him by the adversary. What need is there to say that He is the only High Priest, who alone possesses the knowledge of the worship of God? He is Melchizedek, “King of peace,” the most fit of all to head the race of men. …

Therefore, in this general and primordial law of God, the observance of which, in the case of the tree’s fruit, He had sanctioned, we recognise en closed all the precepts specially of the posterior Law, which germinated when dis closed at their proper times. For the subsequent superinduction of a law is the work of the same Being who had before premised a precept; since it is His province withal subsequently to train, who had before resolved to form, righteous creatures. For what wonder if He extends a discipline who institutes it? if He advances who begins? In short, before the Law of Moses, written in stone-tables, I contend that there was a law unwritten, which was habitually understood naturally, and by the fathers was habitually kept. …

After him brake out a second heretical Theodotus, who again himself introduced a sister-sect, and says that the human being Christ Himself was merely conceived alike, and born, of the Holy Spirit and the Virgin Mary, but that He was inferior to Melchizedek; because it is said of Christ, “Thou art a priest unto eternity, after the order of Melchizedek.” For that Melchizedek, he says, was a heavenly Virtue of pre-eminent grace; in that Christ acts for human beings, being made their Deprecator and Advocate: Melchizedek does so for heavenly angels and Virtues. For to such a degree, he says, is he better than Christ, that he is ἀπάτωρ (fatherless), ἀμήτωρ (motherless), ἀγενεαλογητον (without genealogy), of whom neither the beginning nor the end has been comprehended, nor can be comprehended.

Eran. I think the words of the divine Apostle are as follows; “For this Melchisedec, king of Salem, priest of the most high God who met Abraham returning from the slaughter of the kings, and blessed him; to whom also Abraham gave a tenth part of all; first being by interpretation king of righteousness, and after that also king of Salem, which is king of peace; without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the son of God; abideth a priest continually.” I presume you spoke of this passage.
