The Ecclesiastical History of Theodoret.
“When these actions, in keeping with their course of life, and the impious enterprise which had been long concealed, became tardily known to us, we unanimously ejected them from the Church which worships the divinity of Christ. They then ran hither and thither to form cabals against us, even addressing themselves to our fellow-ministers who were of one mind with us, under the pretence of seeking peace and unity with them, but in truth endeavouring by means of fair words, to sweep some among them away into their own disease. They ask them to write a wordy letter, and then read the contents to those whom they have deceived, in order that they may not retract, but be confirmed in their impiety, by finding that bishops agree with and support their views. They make no acknowledgment of the evil doctrines and practices for which they have been expelled by us, but they either impart them without comment, or carry on the deception by fallacies and forgeries. Thus concealing their destructive doctrine by persuasive and meanly truckling language, they catch the unwary, and lose no opportunity of calumniating our religion. Hence it arises that several have been led to sign their letter, and to receive them into communion, a proceeding on the part of our fellow-ministers which I consider highly reprehensible; for they thus not only disobey the apostolical rule, but even help to inflame their diabolical action against Christ. It is on this account, beloved brethren, that without delay I have stirred myself up to inform you of the unbelief of certain persons who say that “There was a time when the Son of God was not;” and “He who previously had no existence subsequently came into existence; and when at some time He came into existence He became such as every other man is.” God, they say, created all things out of that which was non-existent, and they include in the number of creatures, both rational and irrational, even the Son of God. Consistently with this doctrine they, as a necessary consequence, affirm that He is by nature liable to change, and capable both of virtue and of vice, and thus, by their hypothesis of his having been created out of that which was non-existent, they overthrow the testimony of the Divine Scriptures, which declare the immutability of the Word and the Divinity of the Wisdom of the Word, which Word and Wisdom is Christ. ‘We are also able,’ say these accursed wretches, ‘to become like Him, the sons of God; for it is written,— I have nourished and brought up children.’
When the continuation of this text is brought before them, which is, ‘ and they have rebelled against Me, ’ and it is objected that these words are inconsistent with the Saviour’s nature, which is immutable, they throw aside all reverence, and affirm that God foreknew and foresaw that His Son would not rebel against Him, and that He therefore chose Him in preference to all others. They likewise assert that He was not chosen because He had by nature any thing superior to the other sons of God; for no man, say they, is son of God by nature, nor has any peculiar relation to Him. He was chosen, they allege, because, though mutable by nature, His painstaking character suffered no deterioration. As though, forsooth, even if a Paul and a Peter made like endeavours, their sonship would in no respects differ from His.
“To establish this insane doctrine they insult the Scriptures, and bring forward what is said in the Psalms of Christ, ‘ Thou hast loved righteousness and hated iniquity, therefore thy God hath anointed thee with the oil of gladness above thy fellows.’ Now that the Son of God was not created out of the non-existent, and that there never was a time in which He was not, is expressly taught by John the Evangelist, who speaks of Him as ‘ the only begotten Son which is in the bosom of the Father.’ This divine teacher desired to show that the Father and the Son are inseparable; and, therefore, he said, ‘that the Son is in the bosom of the Father.’ Moreover, the same John affirms that the Word of God is not classed among things created out of the non-existent, for, he says that ‘ all things were made by Him,’ and he also declares His individual personality in the following words: ‘ In the beginning was the Word, and the Word was with God, and the Word was God.…All things were made by Him, and without Him was not any thing made that was made.’ If, then, all things were made by Him, how is it that He who thus bestowed existence on all, could at any period have had no existence himself? The Word, the creating power, can in no way be defined as of the same nature as the things created, if indeed He was in the beginning, and all things were made by Him, and were called by Him out of the non-existent into being. ‘ That which is ’ must be of an opposite nature to, and essentially different from, things created out of the non-existent. This shows, likewise, that there is no separation between the Father and the Son, and that the idea of separation cannot even be conceived by the mind; while the fact that the world was created out of the non-existent involves a later and fresh genesis of its essential nature, all things having been endowed with such an origin of existence by the Father through the Son. John, the most pious apostle, perceiving that the word ‘was’ applied to the Word of God was far beyond and above the intelligence of created beings, did not presume to speak of His generation or creation, nor yet dared to name the Maker and the creature in equivalent syllables. Not that the Son of God is unbegotten, for the Father alone is unbegotten; but that the ineffable personality of the only-begotten God is beyond the keenest conception of the evangelists and perhaps even of angels.
Therefore, I do not think men ought to be considered pious who presume to investigate this subject, in disobedience to the injunction, ‘ Seek not what is too difficult for thee, neither enquire into what is too high for thee.’ For if the knowledge of many other things incomparably inferior is beyond the capacity of the human mind, and cannot therefore be attained, as has been said by Paul, ‘ Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love Him,’ and as God also said to Abraham, that the stars could not be numbered by him; and it is likewise said, ‘ Who shall number the grains of sand by the sea-shore, or the drops of rain?’ how then can any one but a madman presume to enquire into the nature of the Word of God? It is said by the Spirit of prophecy, ‘ Who shall declare His generation?’ And, therefore, our Saviour in His kindness to those men who were the pillars of the whole world, desiring to relieve them of the burden of striving after this knowledge, told them that it was beyond their natural comprehension, and that the Father alone could discern this most divine mystery; ‘ No man, ’ said He, ‘ knoweth the Son but the Father, and no man knoweth the Father save the Son.’ It was, I think, concerning this same subject that the Father said, ‘My secret is for Me and for Mine.’
“But the insane folly of imagining that the Son of God came into being out of that which had no being, and that His sending forth took place in time, is plain from the words ‘which had no being,’ although the foolish are incapable of perceiving the folly of their own utterances. For the phrase ‘He was not’ must either have reference to time, or to some interval in the ages. If then it be true that all things were made by Him, it is evident that every age, time, all intervals of time, and that ‘when’ in which ‘was not’ has its place, were made by Him. And is it not absurd to say that there was a time when He who created all time, and ages, and seasons, with which the ‘was not’ is confused, was not? For it would be the height of ignorance, and contrary indeed to all reason, to affirm that the cause of any created thing can be posterior to that caused by it. The interval during which they say the Son was still unbegotten of the Father was, according to their opinion, prior to the wisdom of God, by whom all things were created. They thus contradict the Scripture which declares Him to be ‘the firstborn of every creature.’ In consonance with this doctrine, Paul with his usual mighty voice cries concerning Him; ‘ whom He hath appointed heir of all things, by whom also He made the worlds ’ ‘ For by Him were all things created that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by Him and for Him: and He is before all things ’ Since the hypothesis implied in the phrase ‘out of the non-existent’ is manifestly impious, it follows that the Father is always Father. And He is Father from the continual presence of the Son, on account of whom He is called Father. And the Son being ever present with Him, the Father is ever perfect, wanting in no good thing, for He did not beget His only Son in time, or in any interval of time, nor out of that which had no previous existence.
“Is it not then impious to say that there was a time when the wisdom of God was not? Who saith, ‘ I was by Him as one brought up with Him: I was daily His delight?’ Or that once the power of God was not, or His Word, or anything else by which the Son is known, or the Father designated, defective? To assert that the brightness of the Father’s glory ‘once did not exist,’ destroys also the original light of which it is the brightness; and if there ever was a time in which the image of God was not, it is plain that He Whose image He is, is not always: nay, by the non-existence of the express image of God’s Person, He also is taken away of whom this is ever the express image. Hence it may be seen, that the Sonship of our Saviour has not even anything in common with the sonship of men. For just as it has been shown that the nature of His existence cannot be expressed by language, and infinitely surpasses in excellence all things to which He has given being, so His Sonship, naturally partaking in His paternal Divinity, is unspeakably different from the sonship of those who, by His appointment, have been adopted as sons. He is by nature immutable, perfect, and all-sufficient, whereas men are liable to change, and need His help. What further advance can be made by the wisdom of God? What can the Very Truth, or God the Word, add to itself? How can the Life or the True Light in any way be bettered? And is it not still more contrary to nature to suppose that wisdom can be susceptible of folly? that the power of God can be united with weakness? that reason itself can be dimmed by unreasonableness, or that darkness can be mixed with the true light? Does not the Apostle say, ‘ What communion hath light with darkness? and what concord hath Christ with Belial?’ and Solomon, that ‘ the way of a serpent upon a rock ’ was ‘ too wonderful ’ for the human mind to comprehend, which ‘rock,’ according to St. Paul, is Christ. Men and angels, however, who are His creatures, have received His blessing, enabling them to exercise themselves in virtue and in obedience to His commands, that thus they may avoid sin. And it is on this account that our Lord being by nature the Son of the Father, is worshipped by all;
