What priestly role did Melchizedek have?
Melchizedek was the priest of the Most High God. In Genesis 14, he is also called king of Salem, a Gentile community, and he brought forth bread and wine. He functioned as a priest before Israel was on the scene.
Les explains that in Genesis 14:18, Melchizedek is introduced as the king of Salem, a Gentile community, because Israel is not yet on the scene. He brought forth bread and wine, and he was the priest of the Most High God. Les notes that this continues his study of the changes in the names of deity through Scripture. He also uses an illustration of a Swiss watch versus a cheap alarm clock to show that it is absurd to claim there is no difference, setting up a point he intends to make in this half hour.
And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God.
