Critically Assess the Traditional Christian Concept of God Being Eternal

The assertion that God is eternal stands as a cornerstone of traditional Christian theology, shaping not only doctrinal understandings but also personal approaches to faith and worship within a British context. Eternity, however, is a term that often defies simple explanation—does it indicate an existence outside of time, entirely untouched by temporal change, or does it refer more to boundless duration, an endless succession of moments? Equally, the notion of “tradition” in Christian thought is complex; while rooted in scriptural authority, it has been powerfully shaped by centuries of philosophical reflection, particularly from the Greco-Roman and medieval European worlds familiar to UK curricula. In this essay, I aim to critically assess the traditional Christian view that God is eternal, drawing on philosophical argument, scriptural interpretation, and modern critiques, ultimately suggesting that whilst the doctrine carries significant intellectual and theological weight, it is not without serious conceptual difficulties.

I. Historical and Philosophical Foundations

Platonic Influences: Eternity as Changelessness

The traditional Christian concept of God’s eternity is profoundly indebted to Platonic philosophy, whose influence filtered into Christian thought primarily through the early Church Fathers. For Plato, particularly in dialogues like *Phaedo* and *Republic*, the realm of ‘Forms’ is characterised as eternal, immutable, and perfect—completely unlike the mutable, finite world. British students will recognise this in the way early Christian theologians, such as Augustine (whose legacy permeates much of Anglican thought), interpreted God as the ultimate, unchanging “Form of the Good”, thus laying the groundwork for a God outside the flow of history.

Boethius and the Eternal Present

Later on, Boethius—a figure with enduring significance, not least due to his prominence in the *Cambridge International* philosophy syllabus—formulated perhaps the most succinct definition of divine eternity: “the simultaneous and complete possession of endless life”. This idea, found in his *Consolation of Philosophy*, means that God’s life is not pieced out moment by moment as ours is, but is wholly present, all at once. The implication is radical: God stands, as it were, on a mountain overlooking the whole landscape of time, seeing all moments—the Norman Conquest as much as the COVID pandemic—in a single, unified gaze.

The Medieval Synthesis: Aquinas and Scholasticism

Building on these classical sources, theologians like Thomas Aquinas synthesised Christian doctrine and Aristotelian logic. Aquinas argued that as “pure act” (*actus purus*), God cannot change nor can He be subject to time, which is essentially “the measure of change” (as Aristotle defined it). For Aquinas, God exists *per se*—that is, by necessity of His own nature—while created beings exist only contingently and temporarily. Bell’s renowned *A New History of Christianity in Britain* traces how such ideas became embedded in wider Christian doctrine, framing God as the “uncaused cause” whose eternity is the precondition for the existence of everything else.

Modern Critiques: Time and Language

However, advances in the philosophy of time, notably in the works of J. M. E. McTaggart and later Anthony Kenny (Chichele Professor of Philosophy at Oxford), began to unsettle such confident assertions. These challenges, ranging from the critique of “simultaneity” to the linguistics of divine attributes, underline the extent to which our talk of eternity may merely reflect human limitations, rather than open a window into God’s true nature.

II. Biblical and Theological Grounds

Scriptural Testimony

The doctrine of God’s eternity is not merely a product of philosophy but finds strong support in biblical witness. Consider, for instance, Psalm 90:2: “Before the mountains were born… from everlasting to everlasting you are God,” or Malachi 3:6: “I the Lord do not change.” Such passages have traditionally been cited in British classrooms (for instance in GCSE and A-Level RS syllabi) as prima facie evidence for God’s timelessness and permanence. Yet biblical language is notoriously rich in metaphor, and other passages show God acting within history—answering prayers, grieving, or responding to events—suggesting a God who is, at least in some ways, engaged with time.

Timelessness Versus Everlastingness

Here a vital distinction emerges: the concept of eternity as timelessness (God wholly *outside* time) versus eternity as everlastingness (God *within* time, but with no beginning or end). Many contemporary scholars, including those cited by Paul Helm in his work *Eternal God*, have pointed out that scripture is ambiguous on this subject. For example, while God is said to be “from everlasting”, He is also described as acting “in the fullness of time” (Galatians 4:4).

Theological Consequences

These nuances deeply impact theology. A timeless God seems abstract, perhaps even remote; if God stands apart from the flux of history, how does He genuinely relate to people, answer prayers, or become incarnate in Christ? Conversely, if God is everlasting but within time, does that not risk making Him subject to change, undermining omniscience or immutability? Rowan Williams, former Archbishop of Canterbury, has reflected insightfully on this problem, suggesting that either option raises difficulties for understanding how God remains involved in creation while yet transcending it.

The Problem of Language

One must also be sensitive to the limits of biblical and human language. Whenever scripture refers to God as “eternal”, it may be employing poetic analogy rather than precise metaphysical description. C. S. Lewis—a British author who has shaped much popular Christian thought—once compared God’s relation to time as that of an author to his novel: the characters’ time is not the author’s time. This analogy helps, but also highlights the gulf separating creature from Creator.

III. Philosophical Critique of the Traditional View

Strengths

On the side of the traditional doctrine, there are significant attractions. If God is truly perfect and immutable, it seems fitting that He is also timeless, untouched by change or decay. Furthermore, His omnipresence and omniscience are neatly explained: all things are equally “present” to an eternal God. This view, as Boethius and Aquinas maintained, offers a robust foundation for assurance in divine providence; God’s purposes are not confounded by the unpredictability of history.

Weaknesses: The Problem of Simultaneity

Yet, as critics have observed, the traditional doctrine soon runs into complications. Anthony Kenny has argued forcefully that the very notion of “simultaneity”—that God is present to all moments at once—is confused. If tomorrow does not yet exist for us, how can it “exist” for God? The problem intensifies when one considers God’s knowledge of “future contingents”—if the future is already “present” to God, does that mean our choices are illusory, undermining free will? These problems are not easily put aside, and have taxed the minds of even the most celebrated theologians in England and beyond.

Human Conceptual Limits

Another, deeper difficulty is whether “eternity” as a concept is even properly grasped by human minds shaped by time. Some have accused traditional theologians of “anthropomorphism reversed”—instead of making God in our own temporal image, we imagine Him as the exact opposite, an equally human construction. As Dorothy Sayers, another great British Christian writer, once noted: “All language about God must ultimately be analogy.”

Scripture and Philosophy: A Tension

There is also considerable debate in contemporary theological circles over whether the traditional eternity concept is as biblical as it is philosophical. The close engagement with Greek metaphysics—Aristotle and Plato—means that God’s “timelessness” might owe more to Athens than to Jerusalem. For instance, many of the descriptions of God acting in time, especially in the lives of Old Testament figures, seem at odds with the idea of pure immobility.

IV. Contemporary Responses and Alternatives

Process Theology and Open Theism

In modern British theology, there has been a significant movement towards reconceiving God’s eternity. “Process Theology” (influenced by British thinker Alfred North Whitehead) and “Open Theism” argue for a God who enters into the dynamic flow of time, responding genuinely to creation. This model preserves God’s relational quality—a point which has struck many as more compatible with the personal God witnessed in the New Testament.

Paul Helm and Revisionary Approaches

Paul Helm, a contemporary British philosopher of religion, has offered a nuanced revision. He maintains that God’s life is not divided into temporal moments, but also resists the idea of all time being “simultaneous” in any straightforward sense. Rather, God knows all events “atemporally”, that is, with knowledge not located at any point in time, but also without importing the paradoxes of simultaneity. This provides, perhaps, a richer way to reconcile tradition with philosophical rigour.

Modern Philosophy of Time

Recent British philosophical debate distinguishes between the A-Theory and B-Theory of time, concepts often introduced at A-level. Under A-Theory, the present is uniquely real; under B-Theory, all moments are equally real—past, present, future. Both theories carry implications for divine eternity: a B-Theorist might support the traditional doctrine, while an A-Theorist may press for an everlasting, temporal God. These contemporary discussions both build on and challenge the inherited tradition.

V. Critical Evaluation and Conclusion

Balancing Metaphysical and Experiential Perspectives

In summary, the traditional Christian doctrine of God’s eternity is both elegant and problematic. Its metaphysical coherence—especially when seen in the classical and medieval tradition—improves our grasp of an ultimate, perfect being. At the same time, however, it sits uncomfortably with our sense of time, relationship, and personal experience of faith.

Theological Implications

These debates have real consequences. If God is utterly timeless, then perhaps prayer, history, and salvation lose their immediacy. If, on the other hand, God is “everlasting”—always within time—then the assurance of God’s transcendence and divine perfection is called into question.

Conceptual Modesty

It must finally be acknowledged that discussions of “eternity” press language to its limits. As literary and philosophical figures from Herbert McCabe to C. S. Lewis have repeatedly reminded the British theological world, our finite perspectives will always fall short of the infinite. Humility, then, is the appropriate posture.

Final Reflection

All told, the traditional Christian concept of God’s eternity holds significant weight and has shaped centuries of thought in the British—indeed, the Western—tradition. It offers a vision of God as the ground of being, unchanging and perfect. Yet, when measured against the strengths of modern philosophical and theological reflection, it is clear that our understanding of eternity must remain provisional, open to revision, and responsive to both reason and revelation. Perhaps, rather than settling on a single, dogmatic view, Christian theology in the UK and beyond might better serve faith and reason alike by embracing the richness—and the mystery—of the eternal God.
