Melchizedek is a son of God who suddenly appears and disappears in history because he incarnate as a full-grown man like Adam and Eve.
Melchizedek and Abraham
(
Genesis 14:17–24)
1This Melchizedek was king of Salem and priest of God Most High.
a He met Abraham returning from the slaughter of the kings and blessed him,
2and Abraham apportioned to him a tenth of everything. First, his name means “king of righteousness.” Then also, “king of Salem” means “king of peace.”
3Without father or mother or genealogy, without beginning of days or end of life, like the Son of God, he remains a priest for all time.
4Consider how great Melchizedek was: Even the patriarch Abraham gave him a tenth of the plunder.
5Now the law commands the sons of Levi who become priests to collect a tenth from the people—that is, from their brothers—though they too are descended from Abraham.
6But Melchizedek, who did not trace his descent from Levi, collected a tenth from Abraham and blessed him who had the promises.
7And indisputably, the lesser is blessed by the greater.
8In the case of the Levites, mortal men collect the tenth; but in the case of Melchizedek, it is affirmed that he lives on.
9And so to speak, Levi, who collects the tenth, paid the tenth through Abraham.
10For when Melchizedek met Abraham, Levi was still in the loin of his ancestor.
