John of Damascus — on Heb 1:9 (ORTHODOX FAITH 4.6)

“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.”
