Early Christian Views of God’s Nature
Early Christian writers described God as one, eternal, uncreated, spiritual, and not like a body or an idol. Writers such as Aristides, Irenaeus, Tertullian, Clement, Origen, and Novatian said God is beyond human grasp and not made of matter. Bible passages like John 4:24, Hebrews 1:3, Romans 1:20, and Acts 17:29 were used to support that view. The main witness is broad, though some texts are indirect or use philosophical language.

What did early Christians believe about the Nature of God?
Early Christian writers usually described God as one, eternal, uncreated, spiritual, and beyond bodily form. Writers like Aristides, Irenaeus, Tertullian, Athenagoras, Clement of Alexandria, Origen, Novatian, and the Apostolic Constitutions repeatedly tied God’s nature to words like essence, immutability, invisibility, and incomprehensibility.
They also used Bible passages such as John 4:24, Hebrews 1:3, Romans 1:20, Acts 17:29, and 1 Corinthians 8:6 to explain that God is not made of matter and is not like idols or human art. The evidence is broad and strong for God’s unity, spiritual nature, and eternal being, though some writers use philosophical terms differently and a few cards are only indirect or about related topics like the Trinity or Christ’s divinity.

Questions Answered by the Sources
Did early Christians teach that God is one in nature or essence?
The strongest sources repeatedly say God is one in nature or essence, and that the divine attributes belong to one God rather than many. Some texts also use this language to argue against pagan polytheism and against dividing the Godhead.
-
Aristides, The Apology Direct teaching
...one united body, is completely in agreement with itself, even so God also is one in His nature. One essence belongs to Him, since He is unchanging in His nature and His essence, and He is not afraid of Himself. If, then, the nature of the gods is one, it is not fitting for one god to chase, kill, or harm another god. If, then, gods are chased and wounded by gods, and some are kidnapped and some struck dead by lightning, it is clear that the nature of their gods is not one. And from this it is known, O King, that they are mistaken when they count and place the natures of their gods under a single nature. If, then, we ought to admire a god that is seen and does not see, how much more worthy of praise is it to believe in a nature that is invisible and sees all? And if it is fitting to approve the works made by a craftsman, how much more fitting is it to glorify the Creator of the craftsman?

Tertullian, Ad Nationes Direct teaching
The nature of God, however, if it be the true one with which you are concerned, is of so definite a character as not to be derived from uncertain speculations, nor contaminated with worthless fables, nor determined by promiscuous conceits.

Arnobius, Against the Heathen Direct teaching
Our opinion on the subject is as follows:— that the whole divine nature, since it neither came into existence at any time, nor will ever come to an end of life, is devoid of bodily features, and does not have anything like the forms with which the termination of the several members usually.

Athenagoras, A Plea for the Christians Direct teaching
...the natures of the two. For we acknowledge a God, and a Son, his Word, and a Holy Spirit, united in essence—the Father, the Son, the Spirit. The Son is the Intelligence, Reason, and Wisdom of the Father, and the Spirit is an effluence, like light from fire. So also we understand that there are other powers, which exercise dominion over matter and by means of it, and one in particular that is hostile to God. Not that anything is really opposed to God, as strife is to friendship according to Empedocles, or as night is to day according to the appearing and disappearing of the stars. For even if anything had set itself against God, it would have ceased to exist, because its structure would have been destroyed by the power and might of God. But this power is opposed to the good that is in God, which belongs to Him by necessity and exists with Him, as color with a body, without which it has no existence. I do not mean that it is part of Him, but an attending property existing with Him, united and blended, just as it is natural for fire to be yellow and the ether dark blue. To the good that is in God, I say, the spirit that is about matter is opposed. He was created by God, just as the

Anonymous, Treatise on Re-Baptism Direct teaching
...Old and New Testament plainly declare. These Scriptures announce, without any obscurity, the Father almighty, the Creator of all things, and His Son. For it will happen to them as it does to one who expects salvation from another God. Then at last, contrary to their opinion, they are condemned to eternal punishment by Christ, the Son of God the Father almighty, the Creator whom they blasphemed, when God begins to judge the hidden things of men according to the Gospel through Christ Jesus, because they did not believe in Him, although they were washed in His name.
-
Acts 17:29 Background
Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising.
-
John 4:24 Background
God is a Spirit: and they that worship him must worship him in spirit and in truth.
Did early Christians say God is spirit and not bodily?
These sources describe God as invisible, spiritual, immaterial, and without bodily parts or form. The Bible cards that best fit this topic emphasize that God is spirit and that human beings should not think of the divine nature as like material images.
-
Tertullian, Against Marcion Direct teaching
...Creator because of the name god, or because of its sound or written form. I claim it because of the essence to which the name belongs. And when I find that this essence alone is unbegotten and unmade, alone eternal, and the maker of all things, I assign and claim the attribute of supremacy not for its name, but for its state; not for its title, but for its condition. And so, because the essence to which I assign this attribute has come to be called god, you think I assign it to the name, because I must use a name to express the essence. Yet it is that essence that belongs to the Being who is called God, and who is considered the great Supreme because of His essence, not because of His name. In short, when Marcion himself gives this quality to his god, he gives it to the nature, not to the word. So then, the supremacy that we ascribe to God because of His essence, and not because of His name, ought, as we maintain, to be equal in both beings who possess that substance for which the name of God is given. For to the extent that they are called gods—that is, supreme beings, on the basis, of course, of their unbegotten and eternal, and therefore great and supreme essence—to that exte

Apostolic Constitutions, Apostolic Constitutions Direct teaching
Great are You, O Lord Almighty, and great is Your power, and there is no limit to Your understanding. You are our Creator and Savior, rich in benefits, patient, and the giver of mercy. You do not take away Your salvation from Your creatures, for You are good by nature, and You spare sinners and invite them to repentance. For warning comes from Your deep compassion. How could we endure if we were required to come to judgment at once, when even after so much patience from You, we hardly escape our miserable condition? The heavens declare Your rule, and the earth trembles with earthquakes and, hanging on nothing, declares Your unshaken firmness. The sea, raging with waves and feeding a flock of countless creatures, is bounded by sand, standing in awe at Your command, and it compels all men to cry out, "How great are Your works, O Lord! In wisdom You have made them all; the earth is full of Your creation." And the shining host of angels and the intellectual spirits say to Palmoni, "There is but one holy Being." And the holy seraphim, together with the six-winged cherubim, who sing to You their song of triumph, cry out with unceasing voices, "Holy, holy, holy, Lord God of hosts! Heaven

Apostolic Constitutions, Apostolic Constitutions Direct teaching
O You, the great Being, O Lord God Almighty, who alone are unbegotten and ruled over by no one; who always are, and were before the world; who need nothing, and are above every cause and beginning; who alone are true, who alone are wise; who alone are the Most High; who are invisible by nature; whose knowledge is without beginning; who alone are good and beyond compare; who know all things before they are; who are acquainted with the most secret things; who are inaccessible and have no superior; the God and Father of Your only begotten Son, of our God and Savior; the Creator of the whole world by Him; whose providence provides for and takes care of all; the Father of mercies and God of all consolation, 2 Corinthians 1:3; who dwell in the highest heavens, and yet look down on the things below: You who appointed the rules of the Church by the coming of Your Christ in the flesh; of which the Holy Spirit is the witness, by Your apostles, and by us the bishops, who by Your grace are here present; who have foreordained priests from the beginning for the government of Your people—Abel in the first place, Seth and Enos, and Enoch and Noah, and Melchizedek and Job; who appointed Abraham, an

Irenaeus, Against Heresies: Book II Direct teaching
...ion, when she should actually precede all others, since God is life, incorruption, and truth. These attributes are not created in a gradual order, but are names of the perfections that always exist in God, as much as it is proper for humans to comprehend and speak of God. The following words are in harmony with the name of God: intelligence, word, life, incorruption, truth, wisdom, goodness, and similar attributes. No one can claim that intelligence is older than life, because intelligence itself is life; nor that life comes after intelligence, such that He who is the intellect of all, which is God, could have ever been without life. But if they claim that life was initially in the Father and was created in the sixth position so that the Word could live, then logically, it should have been sent forth earlier, in the fourth position, so that Nous might have life; and even before that, it should have been with Bythus, so that their Bythus could live. To count Sige along with their Propator and assign her to Him as His partner, while not including Zoe in that number—is this not the height of madness?

Alexander of Alexandria, Epistles on the Arian Heresy Direct teaching
...n investigate the Father, because the nature of rational beings cannot receive the knowledge of His divine generation by the Father. But men who are moved by the Spirit of truth have no need to learn these things from me. For the words spoken before by Christ on this very matter are sounding in our ears: "No man knows the Father, save the Son; and no man knows who the Son is, save the Father." Matthew 11:27. We have learned that He is, equally with the Father, unchangeable and immutable, lacking nothing, the perfect Son, and like the Father. In this alone He is inferior to the Father: that He is not unbegotten. For He is the exact image of the Father, differing from Him in nothing. For it is clear that He is the image fully containing all things by which the greatest likeness is declared, as the Lord Himself taught us when He says, "My Father is greater than I." John 14:28. According to this, we believe that the Son is of the Father, always existing. For He is "the brightness of His glory, the express image of His Father's person." Hebrews 1:3. But let no one take that word "always" in such a way as to raise the suspicion that He is unbegotten, as those imagine whose senses are

Clement of Alexandria, The Stromata (Miscellanies) Supporting witness
...dy have. The knowledge we already have about each thing we study is sometimes only knowledge of its essence, while its functions are unknown. This is true of stones, plants, and animals, whose workings we do not know. Or the knowledge may be of the thing's properties, powers, or, so to speak, the qualities that belong to it. And sometimes we may know one or more of those powers or properties—for example, the desires and affections of the soul—while being ignorant of the essence, and so make that essence the subject of investigation. But in many cases, after our understanding has assumed all these things, the question is this: in which essence do these things inhere? For it is only after we have formed ideas in our mind of both essence and operation that we move on to the question. There are also some things whose operations, along with their essences, we know, but whose modifications we do not know.
