From Against the Pagans (318)
He is God, the living and creative God of the universe, the Word of the good God, who is God in his own right. The Word is different from all created things; he is the unique Word belonging only to the good Father. This is the Word that created this whole world and enlightens it by his loving wisdom. He who is the good Word of the good Father produced the order in all creation, joining opposites together, and forming from them one harmonious sound. He is God, one and only-begotten, who proceeds in goodness from the Father as from the fountain of goodness, and gives order, direction, and unity to creation.
By his eternal Word the Father created all things and implanted a nature in his creatures. He did not want to see them tossed about at the mercy of their own natures, and so be reduced to nothingness. But in his goodness he governs and sustains the whole of nature by his Word (who is himself also God), so that under the guidance, providence, and ordering of that Word, the whole of nature might remain stable and coherent in his light. Nature was to share in the Father’s Word, whose reality is true, and be helped by him to exist, for without him it would cease to be. For unless the Word, who is the very “image of the invisible God, the firstborn of all creation,” kept it in existence it could not exist. For whatever exists, whether visible or invisible, remains in existence through him and in him, and he is also the head of the Church, as we are taught by the ministers of truth in their sacred wriings.
The almighty and most holy Word of the Father pervades the whole of reality, everywhere unfolding his power and shining all things visible and invisible. He sustains it all and binds it together in himself. He leaves nothing devoid of his power but gives life and keeps it in being throughout all of creation and in each individual creature.
St. Athanasius (ca. 298-373) was a bishop and theologian, the great defender of the Nicene confession of Christ’s true divinity. He was the primary spokesman for the orthodox cause at the Council of Nicaea and became Bishop of Alexandria several years later. He also played an important role in finalizing the canon of New Testament books. He is commemorated on May 2 by Western Christians, on May 15 by the Coptic Church, and on January 18 by the other Eastern Orthodox churches.
