As a Catholic, I’m getting a little embarassed here with Catholic ignorance on the “priesthood of Melchizedek”. He was a very curious figure in the Bible, however, as Catholics we consider “Melchizedek ‘priest of God Most High’ as a prefiguration of the priesthood of Christ, the unique ‘high priest after the order of Melchizedek’, by a single offering he has perfected for all time those who are sanctified,’ that is, by the unique sacrifice of the cross”. (CCC par. 1544)
We believe that Melchizedek was a real person with a real priesthood, but also a prefigure or type of Christ. In modern scripture the Lord has provided us with more information about the identity and character of Melchizedek. From the Book of Mormon we have the following information:
Alma 13:
13 And now, my brethren, I would that ye should humble yourselves before God, and bring forth fruit meet for repentance, that ye may also enter into that rest.
14 Yea, humble yourselves even as the people in the days of Melchizedek, who was also a high priest after this same order which I have spoken, who also took upon him the high priesthood forever.
15 And it was this same Melchizedek to whom Abraham paid tithes; yea, even our father Abraham paid tithes of one-tenth part of all he possessed.
16 Now these ordinances were given after this manner, that thereby the people might look forward on the Son of God, it being a type of his order, or it being his order, and this that they might look forward to him for a remission of their sins, that they might enter into the rest of the Lord.
17 Now this Melchizedek was a king over the land of Salem; and his people had waxed strong in iniquity and abomination; yea, they had all gone astray; they were full of all manner of wickedness;
18 But Melchizedek having exercised mighty faith, and received the office of the high priesthood according to the holy order of God, did preach repentance unto his people. And behold, they did repent; and Melchizedek did establish peace in the land in his days; therefore he was called the prince of peace, for he was the king of Salem; and he did reign under his father.
19 Now, there were many before him, and also there were many afterwards, but none were greater; therefore, of him they have more particularly made mention.
In the Book of Doctrine and Covenants, which is another book of Mormon scripture, the following additional information is provided about Melchizedek:
D&C 107:
1 There are, in the church, two priesthoods, namely, the Melchizedek and Aaronic, including the Levitical Priesthood.
2 Why the first is called the Melchizedek Priesthood is because Melchizedek was such a great high priest.
3 Before his day it was called the Holy Priesthood, after the Order of the Son of God.
4 But out of respect or reverence to the name of the Supreme Being, to avoid the too frequent repetition of his name, they, the church, in ancient days, called that priesthood after Melchizedek, or the Melchizedek Priesthood.
5 All other authorities or offices in the church are appendages to this priesthood.
