Against the Arians. (Orationes contra Arianos IV.)

St Athanasius of Alexandria (AD 296–373) · PG 26, 16–490

1. Introduction. Reason for writing; certain persons indifferent about Arianism; Arians not Christians, because sectaries always take the name of their founder
2. Texts explained; Fourthly, Hebrews iii. 2. Introduction; the Regula Fidei counter to an Arian sense of the text; which is not supported by the word 'servant,' nor by 'made' which occurs in it; (how can the Judge be among the 'works' which 'God will bring into judgment?') nor by 'faithful;' and is confuted by the immediate context, which is about Priesthood; and by the foregoing passage, which explains the word 'faithful' as meaning trustworthy, as do 1 Pet. iv. fin. and other texts. On the whole made may safely be understood either of the divine generation or the human creation
3. Texts Explained; Seventhly, John xiv. 10. Introduction. The doctrine of the coinherence. The Father and the Son Each whole and perfect God. They are in Each Other, because their Essence is One and the Same. They are Each Perfect and have One Essence, because the Second Person is the Son of the First. Asterius's evasive explanation of the text under review; refuted. Since the Son has all that the Father has, He is His Image; and the Father is the One God, because the Son is in the Father
4. The substantiality of the Word proved from Scripture. If the One Origin be substantial, Its Word is substantial. Unless the Word and Son be a second Origin, or a work, or an attribute (and so God be compounded), or at the same time Father, or involve a second nature in God, He is from the Father's Essence and distinct from Him.
