Thus, even Christ did not glorify himself, so as to become High Priest, but instead, it was God who said to him: "You are my Son. Today I have begotten you."
Without father, without mother, without genealogy, having neither beginning of days, nor end of life, he is thereby likened to the Son of God, who remains a priest continuously.
