Psalms 105:15

Touch not my anointed ones, and do no malice among my prophets. He speaks of the patriarchs themselves. Let the Jews therefore blush, who say that unless someone is anointed with royal ointment, he cannot be called anointed (christ). For they say this, that our Lord is not the Christ, because he is not anointed with royal ointment. Behold, before the law the patriarchs, not anointed with royal ointment, are called anointed ones (christs). But they are anointed ones (christs) who are anointed with the Holy Spirit. Therefore our Lord too is rightly called Christ. Which they deny, going against the Scriptures.

You are right to conclude that he [Jesus] is called Christ only because of the anointing, just as an apostle is so called because of his apostolic function and an angel from his office as messenger. Names like these clearly indicate certain functions rather than individual realities or specific persons. Even the prophets are called Christs, as it is sung in the Psalms: "Do not touch my Christs, and do not harm my prophets" The prophet Habbakuk also said, "You came forth for the salvation of your people, to save your Christs." But tell me this: Is it not true that even they would admit that there is only one Christ and Son, who is the Lord made man, the Only Begotten of God made flesh?

But after Moses had made his appearance, and had given the law to the children of Israel, and had brought into their memory all the requirements of the law, and all that it behoved men to observe and do under it, and when he delivered over to death only those who should transgress the law, then death was cut off from reigning over all men; for it reigned then over sinners alone, as the law said to it, "Touch not those that keep my precepts." Moses therefore served the ministration of this word upon death, while he delivered up to destruction all others who were transgressors of the law; for it was not with the intent that death might not reign in any territory at all that Moses came, inasmuch as multitudes were assuredly held under the power of death even after Moses. And the law was called a "ministration of death" from the fact that then only transgressors of the law were punished, and not those who kept it, and who obeyed and observed the things which are in the law, as Abel did, whom Cain, who was made a vessel of the wicked one, slew. However, even after these things death wished to break the covenant which had been made by the instrumentality of Moses, and to reign again over the righteous; and with this object it did indeed assail the prophets, killing and stoning those who had been sent by God, on to Zacharias. But my Lord Jesus, as maintaining the righteousness of the law of Moses, was wroth with death for its transgression of the covenant and of that whole ministration, and condescended to appear in the body of man, with the view of avenging not Himself, but Moses, and those who in a continuous succession after him had been oppressed by the violence of death. That wicked one, however, in ignorance of the meaning of a dispensation of this kind, entered into Judas, thinking to slay Him by that man's means, as before he had put righteous Abel to death. But when he had entered into Judas, he was overcome with penitence, and hanged himself; for which reason also the divine word says: "O death, where is thy victory? O death, where is thy sting?" And again: "Death is swallowed up of victory." It is for this reason, therefore, that the law is called a "ministration of death" because it delivered sinners and transgressors over to death; but those who observed it, it defended from death; and these it also established in glory, by the help and aid of our…
