Christ, King and Priest for ever


An excerpt from his A Treatise on the Trinity

Twelfth Sunday in Ordinary Time

Our Savior received a bodily anointing and so became a true king and a true priest. Both king and priest he was of his very self; a savior could be nothing less. Hear in his own words how he himself became a king: I have been appointed king by God on Zion his holy mountain. Hear in the Father’s words that he was a priest: You are a priest for ever in the line of Melchizedek. Aaron was the first under the law to be made a priest by being anointed with chrism, yet the Father does not say, “in the line of Aaron,” lest it be believed that the Savior’s priesthood could be passed on by inheritance, for at that time Aaron’s priesthood was transmitted by lineal descent. But the Savior’s priesthood is not inherited because this priest lives on for ever. Therefore Scripture says: You are a priest for ever in the line of Melchizedek.

There is, therefore, a savior in the flesh who is both a king and a priest, though his anointing was not physical but spiritual. Among the Israelites, those kings and priests who were actually anointed with oil were either kings or priests. No man could be both king and priest; he had to be one or the other. Only Christ was both king and priest; because he had come to fulfil the law, he alone possessed the twofold perfection of kingship and priesthood.


This we know to be true from the Savior himself. When he took the book of Isaiah, he opened it and read: The Spirit of the Lord is upon me because he has anointed me. He then said that the prophecy was fulfilled in the hearing of those listening.

Peter, the prince of the apostles, also taught that the chrism which made the Savior a christ was the Holy Spirit; that is to say, the power of God. When in the Acts of the Apostles Peter spoke to that faithful and merciful man, the centurion, he said among other things: After the baptism which John preached, Jesus of Nazareth, whom God anointed with the Holy Spirit and with power, started out in Galilee and traveled about performing powerful miracles, and freeing all who were possessed by the devil.

So you see that Peter too said that Jesus in his humanity was anointed with the Holy Spirit and with power. Thus Jesus in his humanity truly became the Christ. By the anointing of the Holy Spirit, he was made both king and priest for ever.

Glory to the Father
and to the Son
and to the Holy Spirit:
as it was in the beginning,
is now, and will be forever. Amen
