I've always wondered about him. More so since becoming Catholic since priests are in said to be in the order of Melchizedek. Being a priest forever. I don't quite understand how the RCC makes this connection other than Melchizedek being a priest.
Genesis 14:18
But Melchisedech the
king of Salem, bringing forth bread and wine, for he was the
priest of the most high God, [19] Blessed him, and said: Blessed be Abram by the most high God, who created heaven and earth. [20] And blessed be the most high God, by whose protection the enemies are in thy hands. And he gave him the tithes of all.
Hebrew meaning "King of righteousness."
In the Epistle to the Hebrews the typical character of Melchisedech and its Messianic import are fully explained. Christ is "a priest forever according to the order of Melchisedech" (Hebrews 7:6; Psalm 109:4); "a high priest forever", etc
(Hebrews 6:20), i.e. order or manner (Gesenius), not after the manner of Aaron. The Apostle develops his teaching in Hebrews 7: Melchisedech was a type by reason of his twofold dignity as priest and king,
........by reason of his name, "king of justice",
by reason of the city over which he ruled, "King of Salem, that is, king of peace", and also
because he "without father without mother, without genealogy, having neither beginning of days nor end of life, but likened unto the Son of God, continueth a priest forever."

CHURCH FATHERS: Dialogue 2 (Theodoret)
Orth. For any one willing to consider it with attention it will not be hard to attain perception of the meaning of the words. After saying without father, without mother, without descent, having neither beginning of days nor end of life, the divine Apostle adds made like the Son of God, abides a priest continually. Here he plainly teaches us that the Lord Christ is archetype of Melchisedec in things concerning the human nature. And he speaks of Melchisedec as made like the Son of God. Now let us examine the point in this mannerdo you say that the Lord had a father according to the flesh?
Eran. Certainly not.
Orth. Why?
Eran. He was born of the holy Virgin alone.
Orth. He is therefore properly styled without father?
Eran. True.
Orth. Do you say that according to the divine Nature He had a mother?
Eran. Certainly not.
Orth. For He was begotten of the Father alone before the ages?
Eran. Agreed.
Orth. And yet, as the generation He has of the Father is ineffable, He is spoken of as without descent. Who says the prophet shall declare His generation?
Eran. You are right.
Orth. Thus it becomes Him to have neither beginning of days nor end of life; for He is without beginning, indestructible, and, in a word, eternal, and coeternal with the Father.
Eran. This is my view too. But we must now consider how this fits the admirable Melchisedec.
Orth. As an image and type. The image, as we have just observed, has not all the properties of the archetype. Thus to the Saviour these qualities are proper both by nature and in reality; but the story of the origin of the race has attributed them to Melchisedec. For after telling us of the father of the patriarch Abraham, and of the father and mother of Isaac, and in like manner of Jacob and of his sons, and exhibiting the pedigree of our first forefathers, of Melchisedec it records neither the father nor the mother, nor does it teach that he traced his descent from any one of Noah's sons, to the end that he may be a type of Him who is in reality without father, and without mother. And this is what the divine Apostle would have us understand, for in this very passage he says further, But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.
Eran. Then, since Holy Scripture has not mentioned his parents, can he be called without father and without mother?
Orth. If he had really been without father and without mother, he would not have been an image, but a reality. But since these are his qualities not by nature, but according to the dispensation of the Divine Scripture, he exhibits the type of the reality.
Eran. The type must have the character of the archetype.
Orth. Is man called an image of God?
Eran. Man is not an image of God, but was made in the image of God.
Orth. Listen then to the Apostle. He says: For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God.
Eran. Granted, then, that he is an image of God.
Orth. According to your argument then he must needs have plainly preserved the characters of the archetype, and have been uncreate, uncompounded, and infinite. He ought in like manner to have been able to create out of the non existent, he ought to have fashioned all things by his word and without labour, in addition to this to have been free from sickness, sorrow, anger, and sin, to have been immortal and incorruptible and to possess all the qualities of the archetype.
...
Orth. The
holy Moses when writing the ancient genealogy tells us how Adam being so many years old begot Seth, and when he had lived so many years he ended his life. So too he writes of Seth, of Enoch, and of the rest, but of Melchisedec he mentions neither beginning of existence nor end of life. Thus as far as the story goes he has neither beginning of days nor end of life, but in truth and reality the only begotten Son of God never began to exist and shall never have an end.
Eran. Agreed.
Orth. Then, so far as what belongs to God and is really divine is concerned, Melchisedec is a type of the Lord Christ; but
as far as the priesthood is concerned, which belongs rather to man than to God, the Lord Christ was made a priest after the order of Melchisedec. For Melchisedec was a high priest of the people, and the Lord Christ for all men has made the right holy offering of salvation.
