**Continued from earlier thread…
St. Ambrose (379 A.D.)**
You see what it is in respect whereof the writer calls Him created: “In so far as He took upon Him the seed of Abraham;” plainly asserting the begetting of a body. How, indeed, but in His body did He expiate the sins of the people? In what did He suffer, save in His body—even as we said above: “Christ having suffered in the flesh”? In what is He a priest, save in that which He took to Himself from the priestly nation?2256 **It is a priest’s duty to offer something, and, according to the Law, to enter into the holy places by means of blood; seeing, then, that God had rejected the blood of bulls and goats, this High Priest was indeed bound to make passage and entry into the holy of holies in heaven through His own blood, in order that He might be the everlasting propitiation for our sins. Priest and victim, then, are one; the priesthood and sacrifice are, however, exercised under the conditions of humanity, for He was led as a lamb to the slaughter, and He is a priest after the order of Melchizedek.2257 ** Let no man, therefore, when he beholds an order of human establishment, contend that in it resides the claim of Divinity;2258 **for even that Melchizedek, by whose office Abraham offered sacrifice, the Church doth certainly not hold to be an angel (as some Jewish triflers do), but a holy man and priest of God, who, prefiguring our Lord,**2259 is described as “without father or mother, without history of his descent, without beginning and without end,”2260 in order to show beforehand the coming into this world of the eternal Son of God, Who likewise was incarnate and then brought forth without any father, begotten as God without mother, and was without history of descent, for it is written: “His generation who shall declare?”2261This Melchizedek, then, have we received as a priest of God made upon the model of Christ, but the one we regard as the type, the other as the original. Now a type is a shadow of the truth, and we have accepted the royalty of the one in the name of a single city, but that of the other as shown in the reconciliation of the whole world; for it is written: “God was in Christ, reconciling the world to Himself;”2262 that is to say, [in Christ was] eternal Godhead: or, if the Father is in the Son, even as the Son is in the Father, then Their unity in both nature2263 and operation is plainly not denied.
Augustine (413-426 A.D.)
Christ and Eucharistic sacrifice pre-figured in the story of Abraham and Melchizedek
Then on the invasion of Sodom, when five kings carried on war against four, and Lot was taken captive with the conquered Sodomites, Abraham delivered him from the enemy, leading with him to battle three hundred and eighteen of his home-born servants, and won the victory for the kings of Sodom, but would take nothing of the spoils when offered by the king for whom he had won them. He was then openly blessed by Melchizedek, who was priest of God Most High, about whom many and great things are written in the epistle which is inscribed to the Hebrews, which most say is by the Apostle Paul, though some deny this. For then first appeared the sacrifice which is now offered to God by Christians in the whole wide world, and that is fulfilled which long after the event was said by the prophet to Christ, who was yet to come in the fresh, “Thou art a priest for ever after the order of Melchizedek,” – that is to say, not after the order of Aaron, for that order was to be taken away when the things shone forth which were intimated beforehand by these shadows.
Augustine (417 A.D.)
Christ as our mediator
Of this flesh and blood Melchizedek also, when he blessed Abram himself, gave the testimony which is very well known to Christian believers, so that long afterwards it was said to Christ in the Psalms: “Thou art a Priest for ever, after the order of Melchizedek.” This was not then an accomplished fact, but was still future; yet that faith of the fathers, which is the self-same faith as our own, used to chant it. Now, to all who find death in Adam, Christ is of this avail, that He is the Mediator for life. He is, however, not a Mediator, because He is equal with the Father; for in this respect He is Himself as far distant from us as the Father; and how can there be any medium where the distance is the very same? Therefore the apostle does not say, “There is one Mediator between God and men, even Jesus Christ;” but his words are, “The Man Christ Jesus.”He is the Mediator, then, in that He is man,—inferior to the Father, by so much as He is nearer to ourselves, and superior to us, by so much as He is nearer to the Father. This is more openly expressed thus: “He is inferior to the Father, because in the form of a servant;” superior to us, because without spot of sin.
