- Miscellanies 2.16.72Clement of Alexandria · ca. 198–203 · Critics say joy and pity are passions; but we err if we read Scripture's language about God in a fleshly way, for the prophets spoke as we could hear, the Lord accommodating himself to human weakness.
- Miscellanies 5.11.68Clement of Alexandria · ca. 198–203 · Most people imagine God to be like themselves, but God gives us birth, food, and growth without sharing them; the Hebrew Scriptures' talk of God's hands, eyes, and anger is to be read allegorically.
- Miscellanies 5.11.71Clement of Alexandria · ca. 198–203 · As in the Greek mysteries purification comes before contemplation, so we approach God by stripping away everything bodily until we know what he is not; God is beyond place, time, and name, and is known only by the grace that comes through the Son.
- Miscellanies 5.11.74Clement of Alexandria · ca. 198–203 · We see God now only as in a mirror; Moses allowed one temple and no image, showing that God is invisible and uncircumscribed, and the prophets reject temples and sacrifices as containing God.
- Miscellanies 5.12.78Clement of Alexandria · ca. 198–203 · Plato said the Maker of all cannot be declared to all, having learned from Moses, who entered the thick darkness where God was; Orpheus too says that no mortal sees God, for a cloud surrounds him.
- Miscellanies 5.12.81Clement of Alexandria · ca. 198–203 · Solon, Empedocles, and John agree that God cannot be seen or grasped; God is the first principle, beyond every category, indivisible, infinite, without form or name.
- Miscellanies 5.12.82Clement of Alexandria · ca. 198–203 · The names we give God are not his proper name but aids to thought; God cannot be reached by demonstration and is known only by grace through the Word, as Paul told the Athenians about the unknown god.

- Miscellanies 5.14.133Clement of Alexandria · ca. 198–203 · Pythagorean, Orphic, and comic writers speak of one first principle and one Father of all; Plato's philosophy is the turning of the soul toward the Good; and every nation has a natural preconception of the one Maker.
- Miscellanies 7.5.29Clement of Alexandria · ca. 198–203 · God, who needs nothing, has no need of a temple; his true temple is the church, the assembly of the elect, and the righteous soul of the one who knows is his holy statue.

- Apology 17Tertullian · ca. 197 · Christians worship the one Creator, who is known both from his works and from the testimony of the soul, which naturally calls on God.
- To the Nations 2.2Tertullian · 197 · Philosophers, lacking the fear of God that is the beginning of wisdom, disagree endlessly about the gods, borrowing scraps of Scripture and distorting them.
- The Testimony of the Soul 2Tertullian · ca. 197–198 · Common sayings such as “If God wills” and “God will judge between us” show that the soul naturally knows one good God who judges, even while it worships idols.
- Against Hermogenes 3Tertullian · ca. 200–206 · Answering the argument that God was always Lord and so always had matter to rule, Tertullian distinguishes God, the name of his substance, from Lord, the name of his power, which Scripture gives him only after creation.
- Against Hermogenes 4Tertullian · ca. 200–206 · Tertullian argues that eternity, having no beginning and no end, is the mark proper to God alone, so to make matter eternal is to make it a second god.
- Against Hermogenes 6Tertullian · ca. 200–206 · Tertullian argues that Hermogenes makes God a liar, since God's claims to be alone, first, and unrivalled all apply equally to eternal matter, which is thus set on a level with God.
- Against Hermogenes 7Tertullian · ca. 200–206 · Tertullian argues that eternity admits no degrees, so eternal matter cannot be inferior to God, and he imagines matter itself claiming equality with God.
- Against Marcion 1.3Tertullian · 207/208 (third edition, completed later) · Tertullian argues that God by definition is the supreme great being, which can have no equal, so there can only be one God: “God, if he is not one, is not.”
- Against Marcion 1.4Tertullian · 207/208 (third edition, completed later) · The analogy of many kings, each supreme in his own realm, fails: nothing can be compared with God, and even among kings supremacy finally belongs to only one.
- Against Marcion 1.5Tertullian · 207/208 (third edition, completed later) · If two gods are admitted, there is no reason not to admit many; two equal gods would be pointless and would make worship itself impossible to get right.
- Against Marcion 1.6Tertullian · 207/208 (third edition, completed later) · Marcion's two gods are in fact unequal (a harsh judge and a merely good god), but if both are truly God, neither can be less than the other, so inequality between them is impossible too.
- Against Marcion 1.7Tertullian · 207/208 (third edition, completed later) · That Scripture calls others “gods” proves nothing: supreme greatness belongs to God's eternal substance, not to the name, and so two gods can be neither equal nor unequal.
- Against Marcion 1.9Tertullian · 207/208 (third edition, completed later) · Marcion's god, unknown until Christ, is at best uncertain; and since both gods are claimed to share the same divine nature, the uncertain one must be tested by the pattern of the known Creator, who was never unknown.
- Against Marcion 1.10Tertullian · 207/208 (third edition, completed later) · The Creator has been known since creation, not only since Moses: every human soul naturally speaks of God, so he was never unknown, even in Pontus.
- Against Marcion 1.15Tertullian · 207/208 (third edition, completed later) · Marcion's god has no visible world of his own; and if he made one, the place and matter it required would themselves be gods, so that Marcion's system actually implies nine gods, not two.
- Against Marcion 1.17Tertullian · 207/208 (third edition, completed later) · Saying that Marcion's god saved mankind proves nothing until his existence is shown from works; and a good god who waited so long to reveal himself would be either ignorant, hesitant, powerless, or unwilling.
- Against Marcion 1.22Tertullian · 207/208 (third edition, completed later) · Real goodness in God must be natural and eternal, acting as soon as there is need; a god who let the human race suffer and perish for ages before helping would be malicious, like a doctor who lets a disease worsen to earn a bigger fee.
- Against Marcion 1.25Tertullian · 207/208 (third edition, completed later) · A god of goodness alone, free of all feeling, is the idle god of Epicurus; yet by willing to save mankind Marcion's god already shows desire, care, and rivalry, and so must have the other emotions Marcion denies him.
- Against Marcion 1.26Tertullian · 207/208 (third edition, completed later) · A god who forbids sin but never judges or punishes it in effect permits it; true goodness must hate and punish evil in order to protect the good.
- Against Marcion 2.2Tertullian · 207/208 (third edition, completed later) · Heretics put the Creator on trial because they cannot grasp him, like blind men wishing for a gentler sun; but Scripture teaches that God's ways are beyond human judgment, and even Adam, the first to choose his own opinion over God's, never blamed his Maker.
- Against Marcion 2.3Tertullian · 207/208 (third edition, completed later) · The Creator's goodness is eternal: before anything existed he willed to make a world through which he could be known, so his goodness is older than time itself, unlike the late-arriving goodness of Marcion's god.
- Against Marcion 2.7Tertullian · 207/208 (third edition, completed later) · Having given man free will, God rightly did not snatch it back to prevent the fall; had he done so, Marcion would have called him fickle and faithless.
- Against Marcion 2.11Tertullian · 207/208 (third edition, completed later) · God's severity after the fall (pain in childbirth, the cursed ground, death) followed his original goodness as a response to sin; justice is not evil but the safeguard of goodness.
- Against Marcion 2.12Tertullian · 207/208 (third edition, completed later) · Goodness and justice cannot be split between two gods: from the first days of creation the Creator's justice was at work, separating light from darkness and ordering every part of the world.
- Against Marcion 2.16Tertullian · 207/208 (third edition, completed later) · Anger and jealousy in God are the just instruments of a good judge, like a surgeon's tools; God's feelings share names with ours but, like his “hands” and “eyes,” exist in him in a divine, incorruptible way.
- Against Marcion 2.24Tertullian · 207/208 (third edition, completed later) · When Scripture says God “repented” of making Saul king or of destroying Nineveh, it does not mean God erred; it means a just change of sentence in response to changing human conduct, since God “is not a man, that he should repent.”
- Against Marcion 2.25Tertullian · 207/208 (third edition, completed later) · God's questions to Adam and Cain were not ignorance but invitations to confess, and his “going down” to Sodom was a threat, not uncertainty; Marcion's own god also “came down.”
- Against Marcion 2.27Tertullian · 207/208 (third edition, completed later) · God's human-like actions in the Old Testament belong to the Son, the Word who from the beginning dealt with patriarchs and prophets and was preparing to become man; the invisible Father is never seen, and God's humility is the means of human salvation.
- Against Marcion 2.29Tertullian · 207/208 (third edition, completed later) · Marcion's Antitheses, which set Christ's mercy against the Creator's severity, actually show one God who is both good and just, gentler once his people had been trained; the world itself is built of harmonized opposites made by one Creator.
- Against Praxeas 29Tertullian · ca. 213 or later · Christ died in his human, not his divine, substance; the Monarchians blaspheme by making the Father suffer and be accursed, and even their claim that the Father “suffered with” the Son makes him passible.
- On First Principles 1.1.2Origen · ca. 220–230 (Rufinus's translation 398) · God as consuming fire consumes sins in the soul, and Scripture calls “spirit” what is opposed to body, as in the spiritual sense of the law.
- On First Principles 1.1.5Origen · ca. 220–230 (Rufinus's translation 398) · God is incomprehensible: whatever we understand of him, he surpasses it as the sun surpasses a spark.
- On First Principles 1.1.6Origen · ca. 220–230 (Rufinus's translation 398) · God is a simple intellectual nature, a unity known through his works, needing neither place nor bodily size, as the human mind itself shows.
- On First Principles 1.1.8Origen · ca. 220–230 (Rufinus's translation 398) · Scripture confirms that God is by nature invisible; between Father and Son there is not seeing but knowing.
- On First Principles 1.2.10Origen · ca. 220–230 (Rufinus's translation 398) · God has always been almighty, so there have always been beings over whom he rules; the Son shares the glory of omnipotence, by which all things are subjected through reason, not force.
- On First Principles 2.4.3Origen · ca. 220–230 (Rufinus's translation 398) · The heretics' claim that the Creator was seen while the Father is invisible fails: God is incorporeal and invisible, and between Father and Son, as for Moses, there is knowing rather than seeing.
- On First Principles 4.3.15Origen · ca. 220–230 (Rufinus's translation 398) · Meaning matters more than words: the Greeks' “incorporeal” is Scripture's “invisible,” and the Trinity is wholly incorporeal; Scripture must be judged by the Spirit who inspired it, not by its humble language.
- Fragments on Genesis, column 57Origen · ca. 220-254 · God's foreknowledge is shown from Susanna, the prophecy naming Josiah long before his birth, and Isaiah's prophecy naming Cyrus.
- Fragments on Genesis, column 93Origen · ca. 220-254 · Against those, including Melito, who place the image of God in the body, Origen shows that a literal reading of God's members contradicts itself.
- Fragments on Luke, column 363Origen · ca. 220-254 · The excuses in the parable of the great supper are false doctrine, love of the senses and love of pleasure; God is likened to a man only for our sake, until we can see him as he is.
- PG 12:1053Origen · ca. 220-254 · Origen sets out philosophical definitions of “end” (from Aristotle and the Stoics, via Herophilus) and of “God,” as background to the psalm titles.
- PG 12:1099 (Ps 1–2 LXX)Origen · ca. 220-254 · God “knows” the way of the righteous, Christ, and does not know evil, as his questions to Adam and in the Gospel show; Psalm 2 opens with Origen’s note that some Hebrew copies join it to Psalm 1, as Acts 13:33 does.
- PG 12:1103 (Ps 2 LXX)Origen · ca. 220-254 · On the divine names: Adonai, Iah, and the unpronounced four-letter name written in the old Hebrew script, rendered “Lord” in Greek; and on the Septuagint’s use of the past tense for prophecies about Christ.
- PG 12:1105 (Ps 2 LXX)Origen · ca. 220-254 · The first verses of Psalm 2 are the angels’ words and the reply is the Son’s, who breaks the bonds of sin; God speaks in wrath to bring sinners to repentance, as at Nineveh; anger and wrath are distinguished.
- PG 12:1163 (Ps 4 LXX)Origen · ca. 220-254 · On Ps 4:6, God is light to the pure and consuming fire to vice; as the sun’s light reaches whoever turns to it, so God’s light is imprinted on the mind turned to him, as with Moses’ shining face.
- PG 12:1655 (Ps 138 LXX)Origen · ca. 220-254 · Notes on Psalm 139:8–16 (LXX 138): God's presence everywhere compared with Deuteronomy and Amos, the darkness that cannot overcome the light, and God's book as the contemplation of bodies and incorporeals.
- Refutation of All Heresies 7.19.6Hippolytus of Rome · ca. 222–235 · Aristotle defines the soul as the actuality of an organic body, and God, cause of all good things, is harder still to know.
- Refutation of All Heresies 7.19.7Hippolytus of Rome · ca. 222–235 · Aristotle defines God as thought thinking itself, which Hippolytus calls inconceivable, and holds the world to be eternal.
- Fragment 13 on John 1:18Origen · ca. 226-254 · On John 1:18: God is invisible not because unseen but because by nature incorporeal; the pure in heart approach him with the mind, but no one ‘ever’ sees him while bound to material life; he alone fully knows himself.
- Fragment 49 on John 3:36Origen · ca. 226-254 · On John 3:36: ‘the wrath of God’ means the punishments he sends on the wicked, not a passion in the impassible God.
- Commentary on John 2.172Origen · ca. 230–248 · The darkness around God in Exodus and Psalm 18 means the unknowability of God's depths.
- Commentary on John 13.123Origen · ca. 230–248 · Philosophers dispute whether God is bodily, incorporeal, or beyond being; what does Scripture say?
- Commentary on John 13.124Origen · ca. 230–248 · Scripture calls God spirit, consuming fire, and light.
- Commentary on John 13.125Origen · ca. 230–248 · Taken literally, these texts would make God a body, with absurd consequences that those who hold it cannot answer.
- Commentary on John 13.127Origen · ca. 230–248 · If God were a material body, he would be changeable, since matter can take any quality.

- Theological Oration 2 (Or. 28), On the Doctrine of God 19Gregory of Nazianzus · 380 · Elijah, Manoah, Peter, Isaiah, and Ezekiel saw appearances of God but not his nature.
- Theological Oration 2 (Or. 28), On the Doctrine of God 21Gregory of Nazianzus · 380 · Knowledge of God is the hardest of all: Solomon, Paul, and David all confessed that his ways surpass understanding.
- Theological Oration 4 (Or. 30), On the Son 17Gregory of Nazianzus · 380 · God’s substance cannot be named; the best theologian gathers the fullest partial image of the truth from God’s works.
- Theological Oration 4 (Or. 30), On the Son 18Gregory of Nazianzus · 380 · “He who is” is the most proper name of God, since it expresses being in itself, while “God” and “Lord” are relative terms.
- Theological Oration 4 (Or. 30), On the Son 19Gregory of Nazianzus · 380 · God’s common titles express his authority or his saving plan; the proper names Father, Son, and Holy Spirit distinguish the three.
- Not Three Gods, to Ablabius, part 2Gregory of Nyssa · ca. 380–385 · Gregory argues that calling those who share one nature "many men" is a loose habit of speech, since the nature is one and undivided, and that in speaking of God such looseness is dangerous; he adds that "Godhead" names not the divine nature itself, which is unnameable, but something understood about it.
- Not Three Gods, to Ablabius, part 3Gregory of Nyssa · ca. 380–385 · Divine names signify what God does or is not, not what he is; Gregory derives "Godhead" (θεότης) from "beholding" (θέα) and shows from Scripture that seeing belongs equally to Father, Son, and Holy Spirit.
- Not Three Gods, to Ablabius, part 6Gregory of Nyssa · ca. 380–385 · All providence is one work of the Trinity, not cut three ways; as the one God is called Saviour of all though the Son saves in the grace of the Spirit, so there are not three Gods; and since the divine nature is infinite and above every name, "Godhead" cannot name it.
- To the Greeks, on common notions, part 1Gregory of Nyssa · ca. 380–394 · Gregory argues that "God" names the one divine essence, not the persons, so that while we say "Father and Son and Holy Spirit" we never say "God and God and God," and the three are one God as they are one essence.
- To the Greeks, on common notions, part 2Gregory of Nyssa · ca. 380–394 · We say "three men" only by a loose habit caused by human births, deaths, and changing numbers and by each man's coming from a different parent; none of this applies to the Trinity, whose persons never increase or decrease and come from the one person of the Father, so the three are one God.
- Book of Heresies 155.2Philastrius of Brescia · ca. 380s · Literally, the passage teaches God's invisibility.

- Catechetical Oration 0Gregory of Nyssa · ca. 385–390 · Gregory explains that instruction in the faith must be adapted to each hearer's errors, and begins with the pagan: perfect divinity admits no distinction, so there can be only one God.
- Catechetical Oration 20Gregory of Nyssa · ca. 385–390 · God's goodness, wisdom, justice, and power must all be present together in the incarnation; goodness moved him to save us, and wisdom made that love effective.
- On the Life of Moses 301Gregory of Nyssa · ca. 385–395 · Since the divine Good is unlimited, participation in it can never come to rest, so human perfection lies in always growing in the good; Scripture offers examples, as Isaiah points to Abraham and Sarah.
- On the Life of Moses 317Gregory of Nyssa · ca. 385–395 · Left alone, Moses enters the darkness where God is, receives the teaching about God’s incomprehensibility and the moral law, and is shown the pattern of the tabernacle with its gold, silver, and bronze.
- On the Life of Moses 333Gregory of Nyssa · ca. 385–395 · Loosing the sandals means putting off the “garments of skin” given after the fall; then one learns that only God truly is and all else exists by participation. Such a one can free others, as Moses did with the changed hand and the staff, which figure the Incarnation.
- On the Life of Moses 377Gregory of Nyssa · ca. 385–395 · Seeing God consists in not seeing, for God is beyond all knowledge, as Moses learned in the darkness; any concept that claims to grasp God is an idol; Moses rises from peak to peak, from the darkness to the heavenly tabernacle.
- On the Life of Moses 399Gregory of Nyssa · ca. 385–395 · Gregory asks why Moses, who already spoke with God face to face, asks to see him; the request to see God and the answer about the rock and God’s back cannot be taken literally, since a God with front and back would be a body and so corruptible.
- On the Life of Moses 403Gregory of Nyssa · ca. 385–395 · God grants Moses’ request by refusing it: to see God is never to stop desiring him, since God, the true life, is beyond all knowledge and without limit; a bounded God would be enclosed and overpowered by evil, which is absurd.

- Letter 118.23Augustine of Hippo · ca. 386–430 · Augustine shows that one who knows that God is present everywhere whole, like truth, and that the Word is begotten in a unique way, need not trouble about Anaximenes' view that air is God.
- Letter 147.18Augustine of Hippo · ca. 386–430 · Augustine quotes Ambrose: God is seen only when and in the form he wills, not in his nature; in the resurrection only the pure in heart will see him, by the mind and not the eyes.
- Letter 147.20Augustine of Hippo · ca. 386–430 · The godly long to see God not in the forms he assumes but in his own substance, as Moses asked; this is promised for the next life, when we shall see him as he is.
- Letter 147.22Augustine of Hippo · ca. 386–430 · If angels see God as he is, we shall too when made equal to them; Ambrose's 'form is seen, power is declared' points to an ineffable vision of the mind.
- Letter 147.29Augustine of Hippo · ca. 386–430 · God is not heard by the ears either; the Son declares him as the inner Word, and God, who fills all things, is seen by the pure mind even when thought absent.
- Letter 147.37Augustine of Hippo · ca. 386–430 · Augustine summarizes: God is invisible by nature but appears in chosen forms; his children will see him as he is, as the angels do, with the eyes of the heart.
- Letter 147.46Augustine of Hippo · ca. 386–430 · Augustine lists the truths of faith about God's invisibility, the Trinity, and the resurrection body, from which the spiritually mature have learned that mental sight surpasses bodily sight.

- Letter 162.8Augustine of Hippo · ca. 386–430 · That God cannot be seen with bodily eyes, even Christ's, is not a hidden mystery but plain reason, since God is not a body.
- Letter 162.9Augustine of Hippo · ca. 386–430 · Whatever is hidden about bodies, it is plain that bodies occupy space, so God, who is whole everywhere, cannot be seen with bodily eyes; Augustine asks for a copy of Evodius's lost letter.

- On Free Choice of the Will 1.2Augustine of Hippo · ca. 387–395 · Augustine recalls that this question drove him to the Manichaeans and sets out the faith from which the inquiry starts: one good, almighty Creator, who is not the author of sin, and his begotten Son.
- On Free Choice of the Will 2.6Augustine of Hippo · ca. 387–395 · Reason judges everything below it and is the highest thing in human nature; if something eternal and unchangeable is found above reason, it is God, or God is whatever is higher still.
- On Free Choice of the Will 2.15Augustine of Hippo · ca. 387–395 · Augustine concludes that God exists, either as truth itself or as what is above it, adding that by faith the begotten Wisdom is equal to the Father; Evodius, not yet wise, already knows something of wisdom.
- On the Catholic Way of Life and the Manichaean Way of Life 1.8Augustine of Hippo · ca. 387–389 · From Christ's command to love God with all one's heart, soul, and mind, and from Paul's words in Romans 8, Augustine concludes that God is the highest good.
- On the Catholic Way of Life and the Manichaean Way of Life 1.10Augustine of Hippo · ca. 387–389 · Augustine replies that the catholic Church does not read the Old Testament as describing a repenting, envious, cruel, or bodily God, and that it leads believers from childish to mature understanding of God.
- On the Catholic Way of Life and the Manichaean Way of Life 2.4Augustine of Hippo · ca. 387–389 · Catholic teaching distinguishes God, good by his own nature, from creatures, good by participation and able to fall short; evil is a privation, not an essence, and God is not its author.

- Sermon 7.7Augustine of Hippo · ca. 391-430 · "I am who I am" names God's eternal, unchangeable being, far beyond human reach; "the God of Abraham, Isaac and Jacob" names his mercy toward us.
- Sermon 12.3Augustine of Hippo · ca. 391-430 · Scripture does not say the devil saw God, only that he came into God's sight and heard him, as a blind man can speak with one he cannot see; God is present to every conscience, to the good as father, to the wicked as judge.
- Sermon 21.2Augustine of Hippo · ca. 391-430 · God is not a body to be approached by climbing high, but spirit, near to the humble; he is love, and whoever loves has him near, for every good we enjoy, sin alone excepted, comes from him.

- Sermon 47.30Augustine of Hippo · ca. 391-430 · God belongs whole to each who says “My God,” as a word or the light belongs whole to all; rich and poor reach him alike by loving him, and he possesses us as his field while we possess him as our God.

- Sermon 117.5Augustine of Hippo · ca. 391-430 · Devout ignorance is better than presumptuous knowledge, for God cannot be comprehended, any more than the eye grasps a whole body at once; the pure heart can only touch him and is made blessed thereby, while God gains nothing, and those who turn from him are already punished with blindness.
- Sermon 117.7Augustine of Hippo · ca. 391-430 · Fleshly people transfer the order of human generation to God; it would be better to keep silent about the ineffable, but silence would let weak brothers think the Arians unanswerable.

- Sermon 120.2Augustine of Hippo · ca. 391-430 · The Word of God is not like the sun, which cannot pass through walls and is in one place at a time, but is whole everywhere and penetrates everything; the preacher sees this dimly but lacks words to convey it.

- Sermon 261.3Augustine of Hippo · ca. 391-430 · Like Paul, who said he had not yet laid hold of it, the preacher cannot point to his God with a finger, as to an idol or star, but only stretch out the mind toward him in faith.

- Sermon 277.13Augustine of Hippo · ca. 391-430 · We should not define the spiritual body rashly; but God is not a body, is not seen in a place, and is whole everywhere at once, as the Word is whole with the Father, in the Virgin, and in the infant.
- Sermon 277.14Augustine of Hippo · ca. 391-430 · Whether spiritual eyes will see God is not settled in Scripture as far as Augustine knows; but eyes that see only across space cannot see God, who is in no place, unless they are given another power.

- Against Faustus the Manichaean 22.18Augustine of Hippo · ca. 398–400 · Augustine explains that “jealousy” and “anger” are said of God by a loose use of words or a Hebrew idiom, meaning his watchful care for his people's fidelity and his just punishment.

- Against Faustus the Manichaean 25.2Augustine of Hippo · ca. 398–400 · Augustine refuses to debate God’s finitude with those who think only in bodily terms, and turns the mockery of circumcision back on the Manichaean belief that God is mixed with all flesh.

- Against Faustus the Manichaean 26.5Augustine of Hippo · ca. 398–400 · Augustine explains that even God does not make the past not to have been, since that would make truth false, and that God’s omnipotence does not include dying, though he could change Elijah as he willed.
- Against Faustus the Manichaean 26.6Augustine of Hippo · ca. 398–400 · Augustine answers that God’s unchangeable nature cannot die, though Christ died in the flesh he took, and that Catholics believe Elijah’s translation and Christ’s real birth and death because Scripture testifies to them.
- On the Trinity 1.1Augustine of Hippo · ca. 399–419 · Augustine describes three kinds of error about God (thinking of him as a body, as a created spirit, or as something found nowhere at all) and explains why Scripture uses lowly images and why the mind must be cleansed to see God.

- On the Trinity 5.8Augustine of Hippo · ca. 399–419 · What is said of God absolutely is said of each person and of the Trinity in the singular (one God, one great, one good, one Almighty); Augustine notes that the Greeks say “one ousia, three hypostases.”

- On the Trinity 15.13Augustine of Hippo · ca. 399–419 · God learns nothing through senses or messengers but knows all things eternally, and creatures exist because he knows them; so our knowledge and word are far unlike his knowledge and the Word born of the Father's essence.
