Concept

Theistic Personalism

Intro

Most modern Christians, when they picture God, picture a person. A very big person, knowing everything, able to do anything, loving everyone, but still a person. That picture has a name: theistic personalism. The label was coined by Brian Davies in 2004 as a critical term, and it describes the way much of contemporary philosophy of religion talks about God.

The alternative is classical theism, the older tradition you find in Augustine, Aquinas, the early creeds, and the Reformed scholastics. Classical theism says God is not a person among persons. God is the ground of all being, the source from which everything else gets its existence. Not the biggest item in the universe, but the reason the universe is here at all.

The difference matters because it changes how every other doctrine gets framed. On theistic personalism, God knows things over time, responds to events as they happen, can experience emotions in sequence, and is in some sense in time. On classical theism, God is outside time, his knowledge is one eternal act, and his attributes are not really separate things he has but are identical with who he is.

Richard Swinburne is the leading philosopher of theistic personalism. Alvin Plantinga and William Lane Craig also lean that way, though with various qualifications. On the classical side you find Brian Davies, David Bentley Hart, Edward Feser, and Eleonore Stump.

This page lays out the position, the attributes where it differs from classical theism (simplicity, eternity, impassibility, foreknowledge), where it sits on the wider spectrum that includes open theism and process theism, and the costs and benefits of each side.

In full

Theistic personalism is the view that God is the supreme person, the greatest being among beings, rather than Being Itself. On this view "God" names a singular agent whose perfections (knowledge, power, goodness, love) are the maximum instances of the same kinds of perfections found in creatures, only without limit and without defect. Theistic personalism is associated with much of contemporary analytic philosophy of religion, Richard Swinburne is the paradigm case, and stands opposite classical theism, the patristic-Thomist-Reformed-scholastic tradition that holds God to be ipsum esse subsistens, simple, atemporally eternal, impassible, and pure act. The label theistic personalism was coined as a critical term by Brian Davies in An Introduction to the Philosophy of Religion (3rd ed., 2004); the intramural Christian-philosophical debate between the two positions is among the most consequential of the last fifty years.

The core difference

The disagreement is about what kind of thing God is.

Classical theism (CT). God is not a being but Being Itself (ipsum esse subsistens), the ground of all that is, not a member of any genus. He has no parts, no potential, no temporal succession, no internal complexity. His attributes are not features added to him but are identical with his essence and with each other under different conceptual aspects. Properly speaking, God is not "the greatest being", that phrase puts him on a continuum with creatures, of which he is then the maximal instance. He is outside the continuum entirely. See Classical Theism, Divine Simplicity, Aseity, Actus Purus, Eternity (Divine).
Theistic personalism (TP). God is a being, the supreme being. His perfections are the same in kind as creaturely perfections, only unbounded. He knows propositions, has beliefs, performs actions in sequence, responds to events, experiences emotions analogously to ours, and exists "in time" (or in some kind of temporality), at least since creation. He is a person in roughly the same univocal sense humans are persons, only infinitely greater.

Compressed: CT says God is the source of being, TP says God is the supreme instance of being. CT works analogically (creaturely terms apply to God in a stretched, non-identical way); TP works largely univocally (creaturely terms apply to God in the same sense, with magnitude differences).

What's at stake, the contested attributes

Each contested attribute marks a fork in the road.

Divine simplicity

CT. God has no parts, no real distinction between essence and existence, between attributes, or between God and his acts. There is no composition in God of any kind. The doctrine is patristic (Augustine), Thomistic (ST I, q.3), and Reformed-scholastic (Turretin, the Westminster Confession via "without body, parts, or passions").
TP. Divine simplicity is implausible at best, incoherent at worst, it seems to identify all of God's attributes with each other (so omniscience = omnipotence?) and with God himself (so God = his act of being a single proposition?). Plantinga (in Does God Have a Nature?, 1980) famously rejected divine simplicity as incoherent. Swinburne treats God as having genuinely distinct attributes united in one person.

Aseity and necessary existence

CT. God exists a se, from himself, in himself, depending on nothing. Necessity here is intrinsic to his nature, grounded in the identity of his essence and existence.
TP. Aseity is generally retained, but explicated differently, God is necessary because of the modal structure of reality (e.g., he exists in every possible world) rather than because he is Being Itself. Plantinga's modal ontological argument operates in this register.

Atemporal eternity vs. everlasting temporality

CT. God is atemporally eternal, the whole of his life is possessed all at once, tota simul (Boethius). He has no temporal duration, no before-and-after, no waiting, no surprise.
TP. God is everlasting, he endures through time, has temporal duration, and experiences moments in sequence. Swinburne, Wolterstorff (God Everlasting, 1975), and most open theists hold a temporal view. Some intermediate positions (William Lane Craig) hold that God is atemporal sans creation and temporal with creation.

Impassibility

CT. God is impassible, he cannot be acted upon by his creatures, cannot suffer passions imposed from outside. His "love" and "anger" are not affective states but pure acts of will. Patristic universal consensus; the Reformed confessions encode it; Anselm and Aquinas both defend it.
TP. God is passible, he has genuine emotional life, can be affected by creaturely action, can grieve, rejoice, feel sympathy. Pioneered as a modern doctrine by Jürgen Moltmann's The Crucified God (1972) and reinforced across the analytic literature. Open theism's "responsiveness" is one strong form.

Pure act vs. potency

CT. God is actus purus, pure act with no unrealized potential. He cannot change because there is nothing in him not already actual. See Actus Purus.
TP. God has unrealized potential at minimum in his decisions, his contingent acts, his responses to free creatures. He really does new things. This is most acute in open theism, where God learns the actual future from human choices.

Representative figures

Theistic personalists (or sometimes-personalists)

Richard Swinburne (1934-), Oxford analytic philosopher of religion; the paradigm theistic personalist. The Coherence of Theism (1977, rev. 1993), The Existence of God (1979, 2nd ed. 2004). Holds personalist views on most attributes; treats God as a temporally enduring, freely acting, contingent-decision-making personal agent. See Richard Swinburne.
Alvin Plantinga, sometimes classified as a theistic personalist by Davies and Feser. Rejected divine simplicity explicitly. Modal ontological argument treats God as a necessary being in possible-worlds terms, not as ipsum esse. Has not embraced the label.
Nicholas Wolterstorff, God Everlasting (1975) defends a temporal view of God's eternity on biblical grounds, contra Augustine and Boethius.
William Hasker, Clark Pinnock, Greg Boyd, John Sanders, open theists. The most pronounced personalist position: God genuinely waits, genuinely learns, genuinely takes risks. See Open Theism.
William Lane Craig, a partial personalist. Holds God is temporal sans creation, defends middle knowledge (a non-classical view of divine knowledge), and works largely in analytic mode.

Note: not every analytic philosopher of religion is a theistic personalist. Eleonore Stump, Brian Leftow, and Jeffrey Brower work within or near classical theism while doing analytic work. The methodological style and the metaphysical commitments come apart.

Classical theists / TP-critics

Brian Davies (Dominican, Fordham), coined the term theistic personalism as critique. An Introduction to the Philosophy of Religion (3rd ed., 2004), The Reality of God and the Problem of Evil (2006). Argues TP makes God a being among others, vulnerable to the problem of evil in a way Aquinas's God is not, since the classical God is not a moral agent on the same plane as creatures.
Edward Feser, Thomist popularizer. The Last Superstition (2008), Five Proofs of the Existence of God (2017), Aquinas (2009). Argues the New Atheist objections (Dawkins on "who designed the designer," Russell on God as "first object") only land against TP, not against CT. The TP God is "another being" subject to those questions; the CT God isn't. See Edward Feser.
David Bentley Hart (Orthodox theologian, not analytic), The Experience of God (2013) is a sustained polemic that both atheism and theistic personalism misidentify their target. Argues that "the God of the philosophers and theologians", the classical Being-Itself God, is what every developed religious tradition (Christianity, Vedanta, Sufism, Mahayana) means by "God." See David Bentley Hart.
Thomas Aquinas (historical anchor), Summa Theologiae I, qq. 2-13 are the classical-theist source text. Distinguishes quid est from an est; teaches simplicity, eternity, impassibility, and pure act as the form of any coherent monotheism. See Thomas Aquinas.
Eleonore Stump, Aquinas (2003), The God of the Bible and the God of the Philosophers (2016). Defends classical attributes (simplicity, eternity) against analytic objections while granting some reformulation is needed.
Reformed scholastics (Turretin, Owen, Bavinck), defend classical attributes including simplicity, impassibility, and atemporal eternity in confessional terms. Reformed Dogmatics by Bavinck is the modern Reformed restatement.

Why it matters, the apologetic and pastoral stakes

Apologetic

Coherence of theism. Several New Atheist objections, "who designed the designer," "God can't be a person if he's omnipresent," "if God is timeless he can't act in time", land against TP versions and miss CT versions, because TP makes God a member of a class to which the objections apply. The TP/CT choice changes which objections you have to answer.
Problem of evil. TP treats God as a moral agent whose choices about creaturely suffering are subject to evaluation by the same standards we apply to humans (Why did God allow this? Should he have intervened?). CT denies that God is a moral agent on the same plane, he is the source of the good rather than someone obligated by it. Davies argues this is a major intramural payoff of CT.
God of the philosophers. TP makes the God of philosophy more recognizably "personal" but at the cost of distance from the patristic tradition. CT preserves the patristic-Thomist God at the cost of language that strikes some moderns as remote or impersonal.

Theological

Trinitarian coherence. Divine simplicity is the load-bearing doctrine that lets the Trinity be three persons in one essence without polytheism, the persons are subsisting relations, distinguished only by their relations of origin, in an essence that is not divisible. TP without simplicity risks the persons becoming three distinct centers of consciousness, a social Trinitarianism that is harder to distinguish from tritheism. See Trinity Coherence Defense (Latin-Thomist).
Incarnation. CT makes the Incarnation a paradox (the impassible suffers; the eternal enters time) that requires technical Christological distinctions (communicatio idiomatum). TP makes the Incarnation more naturalistic, the temporal-personal God adopts a temporal-personal nature, but raises the question whether the Son's deity is really being added to.

Pastoral

Prayer. TP makes petitionary prayer intuitive, God hears, responds, possibly changes plans. CT requires more careful articulation, God knows our prayers in his eternal present, and our prayers are eternally part of the world he wills, but he does not "change his mind" in temporal succession. Whether this is a problem depends on what you think prayer is for.
Suffering. TP's passible God suffers with the sufferer; CT's impassible God does not feel pain but is the source of joy who answers suffering by entering it in the Incarnation. Both traditions can pastor well; they pastor differently.

A simplified scoring table

Attribute	Classical Theism	Theistic Personalism
Being	Ipsum esse subsistens (Being Itself)	A being (the supreme being)
Predication	Analogical	Largely univocal
Simplicity	Yes, strict	No (mostly rejected)
Eternity	Atemporal (tota simul)	Everlasting (temporal)
Impassibility	Yes	No (passible)
Pure act	Yes (actus purus)	No (has potential)
Aseity	Yes, essence = existence	Yes, modally necessary
Person language	Analogical, with apophatic caution	Univocal, robust
Patron	Aquinas, Augustine, Bavinck, Hart, Feser, Davies	Swinburne, Plantinga (partial), Wolterstorff, open theists

Where this fits

The TP/CT divide cuts across Catholic, Orthodox, and Protestant lines, though it correlates roughly with method (continental / patristic-Thomist defaults to CT; analytic philosophy of religion defaults to some form of TP) and historical period (pre-modern theology is overwhelmingly classical; post-1970 analytic philosophy of religion is overwhelmingly personalist). The convergence of Hart (Orthodox), Feser (Catholic Thomist), and the Reformed scholastic recovery (Bavinck, Muller, Dolezal's All That Is in God) into a shared CT polemic against TP is one of the more striking intramural alignments of the last decade.

Common questions this page answers

Q: Why must God be personal rather than abstract?

The God who creates, speaks, covenants, judges, loves, and redeems must be a personal God; impersonal-ground-of-being views (pantheism, panentheism, neoplatonic absolute) cannot ground the relational covenantal categories that the biblical witness deploys throughout. Personal theism is the only theism with which the gospel coheres.
