“When they had set forth this formulary, we did not leave without examination that passage in which it is said that the Son is of the substance of the Father, and consubstantial with the Father. Questions and arguments thence arose, and the meaning of the terms was exactly tested. Accordingly they were led to confess that the word consubstantial signifies that the Son is of the Father, but not as being a part of the Father. We deemed it right to receive this opinion; for that is sound doctrine which teaches that the Son is of the Father, but not part of His substance. From the love of peace, and lest we should fall from the true belief, we also accept this view, neither do we reject the term ‘consubstantial.’ For the same reason we admitted the expression, ‘begotten, but not made;’ for they alleged that the word ‘made’ applies generally to all things which were created by the Son, to which the Son is in no respect similar; and that consequently He is not a created thing, like the things made by Him, but is of a substance superior to all created objects. The Holy Scriptures teach Him to be begotten of the Father, by a mode of generation which is incomprehensible and inexplicable to all created beings. So also the term ‘of one substance with the Father,’ when investigated, was accepted not in accordance with bodily relations or similarity to mortal beings. For it was also shown that it does not either imply division of substance, nor abscission, nor any modification or change or diminution in the power of the Father, all of which are alien from the nature of the unbegotten Father. It was concluded that the expression ‘being of one substance with the Father,’ implies that the Son of God does not resemble, in any one respect, the creatures which He has made; but that to the Father alone, who begat Him, He is in all points perfectly like: for He is of the essence and of the substance of none save of the Father. This interpretation having been given of the doctrine, it appeared right to us to assent to it, especially as we were aware that of the ancients some learned and celebrated bishops and writers have used the term ‘consubstantial’ with respect to the divinity of the Father and of the Son.
