Jesus Christ did not glorify Himself in becoming High Priest.

"No one takes this honor upon himself but only when called by God, just as Aaron was."  (Hebrews 5: 4 NABRE)

A number of Scriptures the Holy Spirit gives the Church for today points to the mystery of the priesthood:

#1.  "It was not Christ who glorified himself in becoming high priest."  (Hebrews 5: 5)
#2.  "The Lord has sworn and will not waver: “You are a priest forever in the manner of Melchizedek.”  (Psalm 110: 4)
#3.  “You are a priest forever
according to the order of Melchizedek.”  (Hebrews 5 : 6)
#4. "You have prepared a table before me, and how precious is the chalice that quenches my thirst."  (Psalm 23: 5)

Finally, from the Prayer over the Offerings:  "Grant us, O Lord, we pray, that we may participate worthily in these mysteries, for whenever the memorial of this sacrifice is celebrated the work of our redemption is accomplished.  Through Christ our Lord.  Amen."
