Hebrews 1:9

"You have loved righteousness." These humble things are appropriate after the incarnation, as they are able to receive the lowly nature of the flesh. "therefore God, your God, has anointed you." O God, your God has anointed you. The "you" is through the flesh. For humanity is anointed with the Holy Spirit. It does not operate as it does with mere men, such as prophets and patriarchs. Anointing is, as it were, the entire presence of the anointer. Thus, holy Cyril observed. But see how Eusebius said that Symmachus refers to and rejects this anointing. "Therefore," he says, "God,your God, has anointed you with the oil of joy [χαρᾶς] over your companions." "With the oil of gladness [ἀγαλλιάσεως]." Indeed, the oil of gladness is the Holy Spirit; the people are partakers of Christ. What he means by this is: Not as ordinary men are anointed, so Christ was anointed with the Holy Spirit to a measure, but all was anointed with the Spirit.

It is when the Word was made flesh that we say he received the name of Christ Jesus. Since he was anointed with the oil of gladness—that is to say, anointed with the Spirit by God the Father—he is called Christ, or Anointed. That the anointing was of the humanity no right-minded person would doubt. And the renowned Athanasius says to this effect, somewhere in his discourse, on the saving coming of Christ, "God (the Word), as existing before coming to dwell in the flesh, was not man but God with God, being invisible and impassible. But when he became man, he took the name Christ, because the passion and death are consequent upon this name."38Now, even though sacred Scripture does say, "Therefore God, your God, has anointed you with the oil of gladness," one must know that sacred Scripture frequently uses the past tense for the future. [It says,] for example, "Afterwards, he appeared upon earth and lived among men," for God had not yet been seen by humanity nor had conversed with them when this was said. And again, "By the waters of Babylon, there we sat down and wept," for these things had not yet taken place.

Jesus is the name of the son who was born of a virgin, and, as the angel explained, this name signified that he would save his people from their sins. He who saves from sins is doubtlessly the same one who will save from the corruption of mind and body that happens as a result of sins. "Christ" is a term of priestly and royal dignity, for from "chrism"—that is, an anointing with holy oil—priests and kings were in the law called "christs," and they signified him who appeared in the world as true king and high priest and was anointed with the oil of gladness above those who shared with him. From this anointing, that is, the chrism, he himself is called "Christ," and those who share this anointing, that is, spiritual grace, are called "Christians." In that he is Savior, may he deign to save us from sin. In that he is high priest, may he deign to reconcile us to God the Father. In that he is king, may he deign to give us the eternal kingdom of his Father. He is Jesus Christ our Lord, who with the Father and the Holy Spirit lives and reigns, God for all ages. Amen.
