When Jesus Became Our Great High Priest after the Order of Melchizedek

Jesus is described in Hebrews as our great high priest, but when did this office commence?

Psalm 110 is important in relation to this question, and v. 4 in particular: “Yahweh has sworn and will not change his mind: ‘You are a priest forever after the order of Melchizedek.’” But when did Yahweh historically make this oath?

If anything, the way in which Ps 110:4 is sandwiched by the idea of the Messiah’s enthronement in vv. 1, 5, along with the mention of “the day of your power” in v. 3, suggests that the utterance of the divine oath regarding Christ’s priesthood is linked with his ascension to and enthronement at the right hand of God. Yet I admit that this is not totally clear in the psalm in question.

But there is confirmation of this understanding in the letter to the Hebrews. The author says that Christ did not appoint himself to his priestly office (Heb 5:5). The quotation of Ps 2:7 in Heb 5:5 in juxtaposition with the quotation of Ps 110:4 in Heb 5:6 is important to consider. On the one hand, the wording you are my son is echoed in the voice of God that was heard at Christ’s baptism (e.g., Luke 3:22). On the other hand, Ps 2:7 can be understood as enthronement language. The decree of Ps 2:7 is linked with Yahweh’s establishment of the Messiah as king on Zion (Ps 2:6), which is in response to (see Ps 2:5) a rebellion directed against Yahweh and his Messiah (Ps 2:1-4). It is significant that Ps 2:7 is interpreted by Paul as being fulfilled in Christ’s resurrection (Acts 13:33).

Did the author of Hebrews also understand Ps 2:7 in this way? The language of Heb 5:9-10 suggests that effectively he did. Jesus learned obedience through suffering (Heb 5:8), “and having been made perfect, he became the source of eternal salvation to all who obey him, having been designated by God a high priest after the order of Melchizedek.” In other words, suffering led to obedience, which in turn led to perfection. The time of the aorist passive participle translated as having been designated in v. 10 seems to match with the aorist passive participle translated as having been made perfect in v. 9. It would make sense that the height of Christ’s suffering and obedience was the time when his perfection was complete. The parallel between perfection and designation suggests, therefore, that Christ’s designation as high priest according to the order of Melchizedek took place more or less at the time when his perfection was complete, when his suffering reached its climax. His being designated as such a high priest meant that he could be the source of eternal salvation for those who obey him. This ties Jesus’ designation as high priest in with the time of his death and resurrection.

In a similar way, Heb 6:20 implies that Jesus became high priest at a certain point in time, which in turn enabled him to be a forerunner into the presence of God “within the veil” (Heb 6:19). Thus, according to the author of Hebrews, Jesus’ appointment as high priest occurred shortly before he ascended into the presence of God in the heavenly temple.

Regarding the typological relation between Jesus and Melchizedek, the lack of biblical information concerning the life and particularly the death of Melchizedek is taken as the main point of comparison with Christ: it is as if Melchizedek has not died and continues on as a priest forever, and this continuation in the office of priest is a picture of what is definitely true for Jesus. Yet it is not as if Christ is an eternal priest in a timeless way; but, having entered into that office at some point in time, he continues on in that office forever. The significance drawn from this typological relationship is that the submission of Abraham to Melchizedek proves the superiority of the priestly order of Melchizedek over against the Levitical priesthood, hence the superiority of the new covenant over the old. In the mind of the author, Melchizedek is not viewed as being an eternal priest in a timeless way, but that at some point in his life he became a priest, and that this office seemingly continues on forever. In a similar way, Heb 7:16 says that Jesus became (literally, has become) a priest in the likeness of Melchizedek. Furthermore, the authority for Jesus becoming a priest was “the power of an indestructible life” (Heb 7:16). The quotation of Ps 110:4 in the next verse, therefore, ties Jesus’ priesthood in very closely with his resurrection. Jesus was not appointed as high priest on the basis of the Mosaic regulations concerning the priesthood (Heb 7:28), but as a result of the divine oath recorded in Ps 110:4. Significantly, this oath is described as being “after the law,” i.e., it is not recorded as part of the Mosaic revelation recorded in the Pentateuch (Heb 7:28). Presumably the oath recorded in Ps 110:4 is a prophecy of the oath that was formally made by God around the time of Jesus’ resurrection.

It seems, therefore, that Jesus’ death and resurection marks the time when his office of high priest according to the order of Melchizedek formally commenced. This fits in with the idea that the climax of the ordination ceremony of the priest is the sacrifice of the ram of ordination (אֵיל הַמִּלֻּאִים–the ram of the filling with priestly power and authority) and the sprinking of the priest in its blood (Lev 8:22-30). Jesus’ death on the cross was the climax of his ordination as our great high priest.
