Jesus and Melchizedek
What does it mean in the Bible when it says, "You are a priest forever according to the order of Melchizedek"? Thank you.
The words you cited first occur in Psalm 110:4. The writer to the Hebrews then quotes that verse in Hebrews 5:6 and 7:17.
Melchizedek is someone we meet in Genesis 14:18-20. There he is described as both “king of Salem” and “priest of God Most High.” The combination of king and priest in one person is unique and points ahead in time to Jesus Christ, who is our Prophet, Priest and King.
In his letter to the Hebrews, the inspired writer explains how Jesus is far superior to anyone and anything—including Melchizedek. The origins of Melchizedek are mysterious (Hebrews 7:3). That points to Jesus Christ who, as true man, was conceived by the Holy Spirit and born of the virgin Mary, yet as the eternal Son of God his “origins are from of old, from ancient times” (Micah 5:2). The priesthood of Melchizedek surpassed the Levitical priesthood (Hebrews 7). That points ahead to Jesus Christ, who has a “permanent priesthood” (Hebrew 7:24). Jesus’ sacrifice was “once for all” (Hebrews 7:27).
In short, the phrase you cited is a prophecy (Psalm 110:4) and fulfillment (Hebrews 5:6; 7:17) of Jesus’ service as our great high priest in sacrificing himself for our sins (Hebrews 7:27) and interceding for us when we sin (Hebrews 7:25).
