The Ecclesiastical History of Theodoret.
“And in addition to this pious belief respecting the Father and the Son, we confess as the Sacred Scriptures teach us, one Holy Ghost, who moved the saints of the Old Testament, and the divine teachers of that which is called the New. We believe in one only Catholic Church, the apostolical, which cannot be destroyed even though all the world were to take counsel to fight against it, and which gains the victory over all the impious attacks of the heterodox; for we are emboldened by the words of its Master, ‘ Be of good cheer, I have overcome the world.’ After this, we receive the doctrine of the resurrection from the dead, of which Jesus Christ our Lord became the first-fruits; Who bore a Body, in truth, not in semblance, derived from Mary the mother of God; in the fulness of time sojourning among the race, for the remission of sins: who was crucified and died, yet for all this suffered no diminution of His Godhead. He rose from the dead, was taken into heaven, and sat down at the right hand of the Majesty on high.
“In this epistle I have only mentioned these things in part, deeming it, as I have said, wearisome to dwell minutely on each article, since they are well known to your pious diligence. These things we teach, these things we preach; these are the dogmas of the apostolic Church, for which we are ready to die, caring little for those who would force us to forswear them; for we will never relinquish our hope in them, though they should try to compel us by tortures.
“Arius and Achillas, together with their fellow foes, have been expelled from the Church, because they have become aliens from our pious doctrine: according to the blessed Paul, who said, ‘If any of you preach any other gospel than that which you have received, let him be accursed, even though he should pretend to be an angel from heaven,’ and ‘ But if any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness, he is proud, knowing nothing,’ and so forth. Since, then, they have been condemned by the brotherhood, let none of you receive them, nor attend to what they say or write. They are deceivers, and propagate lies, and they never adhere to the truth. They go about to different cities with no other intent than to deliver letters under the pretext of friendship and in the name of peace, and by hypocrisy and flattery to obtain other letters in return, in order to deceive a few ‘ silly women who are laden with sins.’ I beseech you, beloved brethren, to avoid those who have thus dared to act against Christ, who have publicly held up the Christian religion to ridicule, and have eagerly sought to make a display before judicial tribunals, who have endeavoured to excite a persecution against us at a period of the most entire peace, and who have enervated the unspeakable mystery of the generation of Christ. Unite unanimously in opposition to them, as some of our fellow-ministers have already done, who, being filled with indignation, wrote to me against them, and signed our formulary.
“I have sent you these letters by my son Apion, the deacon; being those of (the ministers in) all Egypt and the Thebaid, also of those of Libya, and the Pentapolis, of Syria, Lycia, Pamphylia, Asia, Cappadocia, and in the other adjoining countries. Whose example you likewise, I trust, will follow. Many kindly attempts have been made by me to gain back those who have been led astray, but no remedy has proved more efficacious in restoring the laity who have been deceived by them and leading them to repentance, than the manifestation of the union of our fellow-ministers. Salute one another, with the brotherhood that is with you. I pray that you may be strong in the Lord, my beloved, and that I may receive the fruit of your love to Christ.
“The following are the names of those who have been anathematized as heretics: among the presbyters, Arius; among the deacons, Achillas, Euzoius, Aïthales, Lucius, Sarmates, Julius, Menas, another Arius, and Helladius.”
Alexander wrote in the same strain to Philogonius, bishop of Antioch, to Eustathius, who then ruled the church of the Berœans, and to all those who defended the doctrines of the Apostles. But Arius could not endure to keep quiet, but wrote to all those whom he believed to agree with him in opinion. His letter to Eusebius, bishop of Nicomedia, is a clear proof that the divine Alexander wrote nothing that was false concerning him. I shall here insert his letter, in order that the names of those who were implicated in his impiety may become generally known.
Chapter IV.—
The Letter of Arius to Eusebius, Bishop of Nicomedia
“ To his very dear lord, the man of God, the faithful and orthodox Eusebius, Arius, unjustly persecuted by Alexander the Pope, on account of that all-conquering truth of which you also are a champion, sendeth greeting in the Lord.
“Ammonius, my father, being about to depart for Nicomedia, I considered myself bound to salute you by him, and withal to inform that natural affection which you bear towards the brethren for the sake of God and His Christ, that the bishop greatly wastes and persecutes us, and leaves no stone unturned against us. He has driven us out of the city as atheists, because we do not concur in what he publicly preaches, namely, God always, the Son always; as the Father so the Son; the Son co-exists unbegotten with God; He is everlasting; neither by thought nor by any interval does God precede the Son; always God, always Son; he is begotten of the unbegotten; the Son is of God Himself. Eusebius, your brother bishop of Cæsarea, Theodotus, Paulinus, Athanasius, Gregorius, Aetius, and all the bishops of the East, have been condemned because they say that God had an existence prior to that of His Son; except Philogonius, Hellanicus, and Macarius, who are unlearned men, and who have embraced heretical opinions. Some of them say that the Son is an eructation, others that He is a production, others that He is also unbegotten. These are impieties to which we cannot listen, even though the heretics threaten us with a thousand deaths. But we say and believe, and have taught, and do teach, that the Son is not unbegotten, nor in any way part of the unbegotten; and that He does not derive His subsistence from any matter; but that by His own will and counsel He has subsisted before time, and before ages, as perfect God, only begotten and unchangeable, and that before He was begotten, or created, or purposed, or established, He was not. For He was not unbegotten. We are persecuted, because we say that the Son has a beginning, but that God is without beginning. This is the cause of our persecution, and likewise, because we say that He is of the non-existent. And this we say, because He is neither part of God, nor of any essential being. For this are we persecuted; the rest you know. I bid thee farewell in the Lord, remembering our afflictions, my fellow-Lucianist, and true Eusebius.”
Of those whose names are mentioned in this letter, Eusebius was bishop of Cæsarea, Theodotus of Laodicea, Paulinus of Tyre, Athanasius of Anazarbus, Gregorius of Berytus, and Aetius of Lydda. Lydda is now called Diospolis. Arius prided himself on having these men of one mind with himself. He names as his adversaries, Philogonius, bishop of Antioch, Hellanicus, of Tripolis, and Macarius, of Jerusalem. He spread calumnies against them because they said that the Son is eternal, existing before all ages, of equal honour and of the same substance with the Father.
When Eusebius received the epistle, he too vomited forth his own impiety, and wrote to Paulinus, chief of the Tyrians, in the following words.
Chapter V
.— The Letter of Eusebius, Bishop of Nicomedia, to Paulinus, Bishop of Tyre .
“ To my lord Paulinus, Eusebius sendeth greeting in the Lord.
“The zeal of my lord Eusebius in the cause of the truth, and likewise your silence concerning it, have not failed to reach our ears. Accordingly, if, on the one hand, we rejoiced on account of the zeal of my lord Eusebius; on the other we are grieved at you, because even the silence of such a man appears like a defeat of our cause. Hence, as it behoves not a wise man to be of a different opinion from others, and to be silent concerning the truth, stir up, I exhort you, within yourself the spirit of wisdom to write, and at length begin what may be profitable to yourself and to others, specially if you consent to write in accordance with Scripture, and tread in the tracks of its words and will.
“We have never heard that there are two unbegotten beings, nor that one has been divided into two, nor have we learned or believed that it has ever undergone any change of a corporeal nature; but we affirm that the unbegotten is one and one also that which exists in truth by Him, yet was not made out of His substance, and does not at all participate in the nature or substance of the unbegotten, entirely distinct in nature and in power, and made after perfect likeness both of character and power to the maker. We believe that the mode of His beginning not only cannot be expressed by words but even in thought, and is incomprehensible not only to man, but also to all beings superior to man. These opinions we advance not as having derived them from our own imagination, but as having deduced them from Scripture, whence we learn that the Son was created, established, and begotten in the same substance and in the same immutable and inexpressible nature as the Maker; and so the Lord says, ‘ God created me in the beginning of His way; I was set up from everlasting; before the hills was I brought forth.’
“If He had been from Him or of Him, as a portion of Him, or by an emanation of His substance, it could not be said that He was created or established; and of this you, my lord, are certainly not ignorant. For that which is of the unbegotten could not be said to have been created or founded, either by Him or by another, since it is unbegotten from the beginning. But if the fact of His being called the begotten gives any ground for the belief that, having come into being of the Father’s substance, He also has from the Father likeness of nature, we reply that it is not of Him alone that the Scriptures have spoken as begotten, but that they also thus speak of those who are entirely dissimilar to Him by nature. For of men it is said, ‘ I have begotten and brought up sons, and they have rebelled against me;’ and in another place, ‘ Thou hast forsaken God who begat thee;’ and again it is said, ‘ Who begat the drops of dew?’ This expression does not imply that the dew partakes of the nature of God, but simply that all things were formed according to His will. There is, indeed, nothing which is of His substance, yet every thing which exists has been called into being by His will. He is God; and all things were made in His likeness, and in the future likeness of His Word, being created of His free will. All things were made by His means by God. All things are of God.
