Justin Martyr
"For, in the name of God, the Father and Lord of the universe, and of our Savior Jesus Christ, and of the Holy Spirit, they then receive the
washing with water" (First Apol., LXI).
Origen
"For if [the Holy Spirit were not eternally as He is, and had received knowledge at some time and then became the Holy Spirit] this were the case, the Holy Spirit would never be reckoned in the unity of the Trinity, i.e., along with the unchangeable Father and His Son, unless He had always been the Holy Spirit." (Alexander Roberts and James Donaldson, eds., The Ante-Nicene Fathers, Grand Rapids: Eerdmans, 1975 rpt., Vol. 4, p. 253, de Principiis, 1.111.4)
Justin Martyr
“God speaks in the creation of man with the very same design, in the following words: ‘Let us make man after our image and likeness.’ . . . I shall quote again the words narrated by Moses himself, from which we can indisputably learn that [God] conversed with someone numerically distinct from himself and also a rational being. . . . But this offspring who was truly brought forth from the Father, was with the Father before all the creatures, and the Father communed with him” (Dialogue with Trypho the Jew 62 [A.D. 155]).
Chapter 36. Different modes of prophecy
But when you hear the utterances of the prophets spoken as it were personally, you must not suppose that they are spoken by the inspired themselves, but by the Divine Word who moves them. For sometimes He declares things that are to come to pass, in the manner of one who foretells the future; sometimes He speaks as from the person of God the Lord and Father of all; sometimes as from the person of Christ; sometimes as from the person of the people answering the Lord or His Father, just as you can see even in your own writers, one man being the writer of the whole, but introducing the persons who converse. And this the Jews who possessed the books of the prophets did not understand, and therefore did not recognise Christ even when He came, but even hate us who say that He has come, and who prove that, as was predicted, He was crucified by them.
Chapter 37. Utterances of the Father
And that this too may be clear to you, there were spoken from the person of the Father through Isaiah the Prophet, the following words: The ox knows his owner, and the ass his master's crib; but Israel does not know, and My people has not understood. Woe, sinful nation, a people full of sins, a wicked seed, children that are transgressors, you have forsaken the Lord. And again elsewhere, when the same prophet speaks in like manner from the person of the Father, What is the house that you will build for Me? Says the Lord. The heaven is My throne, and the earth is My footstool. Isaiah 66:1 And again, in another place, Your new moons and your sabbaths My soul hates; and the great day of the fast and of ceasing from labour I cannot away with; nor, if you come to be seen of Me, will I hear you: your hands are full of blood; and if you bring fine flour, incense, it is abomination unto Me: the fat of lambs and the blood of bulls I do not desire. For who has required this at your hands? But loose every bond of wickedness, tear asunder the tight knots of violent contracts, cover the houseless and naked, deal your bread to the hungry. Isaiah 1:14, Isaiah 58:6 What kind of things are taught through the prophets from [the person of] God, you can now perceive.
Chapter 38. Utterances of the Son
And when the Spirit of prophecy speaks from the person of Christ, the utterances are of this sort: I have spread out My hands to a disobedient and gainsaying people, to those who walk in a way that is not good. Isaiah 65:2 And again: I gave My back to the scourges, and My cheeks to the buffetings; I turned not away My face from the shame of spittings; and the Lord was My helper: therefore was I not confounded: but I set My face as a firm rock; and I knew that I should not be ashamed, for He is near that justifies Me. Isaiah 50:6 And again, when He says, They cast lots upon My vesture, and pierced My hands and My feet. And I lay down and slept, and rose again, because the Lord sustained Me. And again, when He says, They spoke with their lips, they wagged the head, saying, Let Him deliver Himself. And that all these things happened to Christ at the hands of the Jews, you can ascertain. For when He was crucified, they did shoot out the lip, and wagged their heads, saying, Let Him who raised the dead save Himself. Matthew 27:39
Chapter 39. Direct predictions by the Spirit
And when the Spirit of prophecy speaks as predicting things that are to come to pass, He speaks in this way: For out of Zion shall go forth the law, and the word of the Lord from Jerusalem. And He shall judge among the nations, and shall rebuke many people; and they shall beat their swords into ploughshares, and their spears into pruning-hooks: nation shall not lift up sword against nation, neither shall they learn war any more. Isaiah 2:3 And that it did so come to pass, we can convince you. For from Jerusalem there went out into the world, men, twelve in number, and these illiterate, of no ability in speaking: but by the power of God they proclaimed to every race of men that they were sent by Christ to teach to all the word of God; and we who formerly used to murder one another do not only now refrain from making war upon our enemies, but also, that we may not lie nor deceive our examiners, willingly die confessing Christ. For that saying, The tongue has sworn but the mind is unsworn, might be imitated by us in this matter. But if the soldiers enrolled by you, and who have taken the military oath, prefer their allegiance to their own life, and parents, and country, and all kindred, though you can offer them nothing incorruptible, it were verily ridiculous if we, who earnestly long for incorruption, should not endure all things, in order to obtain what we desire from Him who is able to grant it.
