Defence of the Council's Phrases, from the essence, And one in essence. Objection that the phrases are not scriptural; we ought to look at the sense more than the wording; evasion of the Ariansas to the phrase of God which is in Scripture; their evasion of all explanations but those which the Council selected, which were intended to negative the Arianformulæ; protest against their conveying any material sense
18 Now Eusebius and his fellows were at the former period examined at great length, and convicted themselves, as I said before; on this they subscribed; and after this change of mind they kept in quiet and retirement; but since the present party, in the fresh arrogance of irreligion, and in dizziness about the truth, are full set upon accusing the Council, let them tell us what are the sort of Scriptures from which they have learned, or who is the Saint by whom they have been taught, that they have heaped together the phrases, 'out of nothing,' and 'He was not before His generation,' and 'once He was not,' and 'alterable,' and 'pre-existence,' and 'at the will.' which are their fables in mockery of the Lord. For the blessed Paul in his Epistle to the Hebrews says, 'By faith we understand that the ages were framed by the Word of God, so that that which is seen was not made of things which do appear.' But nothing is common to the Word with the ages; for He it is who is in existence before the ages, by whom also the ages came to be. And in the Shepherd it is written (since they allege this book also, though it is not of the Canon), 'First of all believe, that God is one, who created all things, and arranged them, and brought all things from nothing into being;' but this again does not relate to the Son, for it speaks concerning all things which came to be through Him, from whom He is distinct; for it is not possible to reckon the Framer of all with the things made by Him, unless a man is so beside himself as to say that the architect also is the same as the buildings which he rears.
Why then, when they have invented on their part unscriptural phrases, for the purposes of irreligion, do they accuse those who are religious in their use of them? For irreligiousness is utterly forbidden, though it be attempted to disguise it with artful expressions and plausible sophisms; but religiousness is confessed by all to be lawful, even though presented in strange phrases, provided only they are used with a religious view, and a wish to make them the expression of religious thoughts. Now the aforesaid grovelling phrases of Christ's enemies have been shown in these remarks to be both formerly and now replete with irreligion; whereas the definition of the Council against them, if accurately examined, will be found to be altogether a representation of the truth, and especially if diligent attention be paid to the occasion which gave rise to these expressions, which was reasonable, and was as follows:—
19. The Council wishing to do away with the irreligious phrases of the Arians, and to use instead the acknowledged words of the Scriptures, that the Son is not from nothing but 'from God,' and is 'Word' and 'Wisdom,' and not creature or work, but a proper offspring from the Father, Eusebius and his fellows, led by their inveterate heterodoxy, understood the phrase 'from God?' as belonging to us, as if in respect to it the Word of God differed nothing from us, and that because it is written, 'There is one God, from whom, all things;' and again, 'Old things are passed away, behold, all things have become new, and all things are from God.' But the Fathers, perceiving their craft and the cunning of their irreligion, were forced to express more distinctly the sense of the words 'from God.' Accordingly, they wrote 'from the essence of God,' in order that 'from God?' might not be considered common and equal in the Son and in things originate, but that all others might be acknowledged as creatures, and the Word alone as from the Father. For though all things be said to be from God, yet this is not in the sense in which the Son is from Him; for as to the creatures, 'of God?' is said of them on this account, in that they exist not at random or spontaneously, nor come to be by chance, according to those philosophers who refer them to the combination of atoms, and to elements of similar structure—nor as certain heretics speak of a distinct Framer,— nor as others again say that the constitution of all things is from certain Angels;— but in that (whereas God is), it was by Him that all things were brought into being, not being before, through His Word; but as to the Word, since He is not a creature, He alone is both called and is 'from the Father.' and it is significant of this sense to say that the Son is 'from the essence of the Father,' for to nothing originate does this attach. In truth, when Paul says that 'all things are from God,' he immediately adds, 'and one Lord Jesus Christ, through whom all things,' in order to show all men, that the Son is other than all these things which came to be from God (for the things which came to be from God, came to be through His Son); and that he had used his foregoing words with reference to the world as framed by God, and not as if all things were from the Father as the Son is. For neither are other things as the Son, nor is the Word one among others, for He is Lord and Framer of all; and on this account did the Holy Council declare expressly that He was of the essence of the Father, that we might believe the Word to be other than the nature of things originate, being alone truly from God; and that no subterfuge should be left open to the irreligious. This then was the reason why the Council wrote 'of the essence.'
