True theology, both archetypal and ectypal, is knowledge that stands beyond doubt in contrast to the depraved opinion of false theology. Archetypal theology is that theology which God knows “in se” (in Himself) while ectypal theology is true theology that is accommodated to creaturely understanding. True theology is one in its essence, whether it is found in God himself or understood by his creatures. The divisions of this theology into archetypal and ectypal respects the fact that there is not a single species of theology understood by degrees. In other words, God’s understanding and man’s understanding do not merely differ by degree of the same knowledge. Rather, this singular theology is understood absolutely and infinitely by the Creator (archetypal) while finitely and relatively by the creature (ectypal).
Finite truth is grounded in the one, all-encompassing truth of God’s mind: not only theology, but all human knowledge looks to divine knowledge as its source and goal. The archetype is theology in the truest sense, while all ectypal forms only bear a similitude to the archetype. Theology is in intelligent creatures as an image of the Creator. Theology is in God formally and eminently as His essential wisdom. He does not learn things by examining them or reasoning discursively about facts outside Himself but His is a simple intelligence to which all others can only be related by analogy. God knows things in Himself because it is in His essence to know. Creatures must discursively reason knowledge only insofar as they can analogically understand it but can never have knowledge as God has.
The fact of the divine archetype is crucial to the existence of true yet finite human theology. God understands divine things as He completely understands Himself. The secret things belong to Him alone and we do not peer into them nor can we but are to rely upon that which He accommodates to us. This understanding also guards against making the Creator “one of us”. Wisdom, for instance, does not indicate a genus of wise things of which God is one. Rather wisdom is an attribute of God: it is divine wisdom in the sense of being identical with the divine essence in its simplicity and freedom from composition. A creature is said to be wise only insofar as it images the Creator but it can never possess divine wisdom as this is of the essence of God Himself.
Since divine knowledge is uncreated and identical with the essence of God, it must also be understood that it is incommunicable as are all the divine attributes when defined strictly as speaking of God. God does not share His essence with creatures. All that can be naturally communicated to created things of ultimate wisdom are faint images or vestiges. There is no analogical path from the created order to a full knowledge of god. It is thus God himself who is the source, origin, and efficient cause of what we know as true theology. God’s infinite self-knowledge is transmitted to things in the created order. All things receive the imprint of God and finite creatures’ apprehension of revelation rests upon the image of God. As Augustine holds: “God alone is the theologian and we are truly his disciples.”
Though this distinction of knowledge and theology is very complex it should not be viewed as a form of rationalism. The human mind is radically limited and separated from God’s perfect divine wisdom. It has no power of ascent into divine things apart from the help of God. The sovereignty and transcendence of God is preserved and man understands the gracious nature of revelation and that we understand only insofar as God is kind to reveal to His creatures. In short, in contrast to modern notions, man is not independent in his search for truth but all knowledge is fully reliant upon God.
Thus we must understand that all finite theology is ectypal. In noting this limitation, this is not to state that ectypal theology is one set of truths while archetypal is another. Rather, ectypal theology is the same Truth accommodated to creaturely understanding. God accommodates His truth to human capacity. Revelation, whether natural or supernatural, is suited to the present conditions of human knowing. This act of accommodation belongs to God and God determines the form of knowledge that we have of Him. Against any neo-Orthodox notions that God’s “otherness” makes it impossible for God to communicate via human forms, the Scriptures preserve the transcendence of God in knowing things comprehensively while being able, as Creator, to communicate to His creatures. Ectypal theology is not “another Truth” but is, as it were, God lisping truth to us as a father lisps to His child.
Ectypal theology is also meant to be understood as the perfect form of true theology accommodated to creaturely understanding. It consists of the entire body, natural and supernatural, of knowledge that God has been pleased to reveal to His creatures. Yet, although this true Ectypal theology is revealed, man does not always properly apprehend the things that are revealed to Him. Not only does Sin darken man’s understanding such that he cannot have proper fruition in the natural order nor can he discern spiritual things while unregenerated but even regenerate man is still limited in what he can apprehend of the corpus of God’s truth. God has made our pilgrimage on this earth such that we will not have full happiness and blessedness in His truth but it is one of the things that we are to strive toward as a spiritual discipline as we pursue wisdom and it is also something that the Scriptures reveal that we will see fully only after we have been glorified. Paul reminds believers in 1 Corinthians not to become haughty and arrogant in our knowledge believing we have attained the fullness thereof. While we are sojourners, we know only in part but that imperfect knowledge is sufficient for us to know and be convinced that perfection is not present but is to be some day hoped for. Yet, the hope for perfect knowledge is not that our minds will become co-extensive with God’s own but that, as creatures, we will have the fullness of knowledge that God is able to analogically communicate to His creatures. Even in consummation and in glory we will still be creatures and God will be the Creator.
We have in our midst the perfect human, ectypal theology, but it cannot be perfectly exposited by us – not because of our finitude, but because of our sin and the incompleteness of our sanctification. Our only hope for attaining a saving knowledge of God lies in the fact that Scripture and its perfection is joined to our imperfection according to the fact that we have been united with Christ and that the Holy Spirit is using that perfect Word to transform us by the renewing of our minds.
In contrast to this Biblical form of knowledge, human philosophers do not allow analogical reasoning to understand the world. They start from nature and try to argue for a god who must be finite in nature. It starts with a "mute" universe that has no revelation and makes it revelational only with respect to the autonomous mind of man. No distinction is made between Creator and creature.
Kant's great contribution to philosophy consisted in stressing the activity of the experiencing subject. Kant argued that since it is the thinking subject that itself contributes the categories of universality and necessity, we must not think of these as covering any reality that exists or may exist wholly independent of the human mind. The validity of universals is to be taken as frankly due to a motion and a vote; it is conventional and nothing more.
Plato and Aristotle, as well as Kant, assumed the autonomy of man. On such a basis man may reason univocally (have the same mind as God) and reach a God who is just an extension of the creature or he may reason equivocally and reach a God who has no contact with him at all. Man is left with either God being part of nature (pantheism) or being so transcendent that He cannot get into nature (deism).
We're now left with a world where the scientist supposedly interacts with the physical world and can learn about the world apart from any reference to God and "ministers" who speak about God's revelation that has no reference to history and interaction with the world. Man is fractured intellectually where reason deals with things of the world and faith deals with things that cannot affect reason or the world.
The very idea of Kant's Copernican revolution was that the autonomous mind itself must assume the responsibility for making all factual differentiation and logical validation. To such a mind the God of Christianity cannot speak. Such a mind will hear no voice but its own.
God's revelation in nature, however, was always meant to serve alongside His special revelation. God is a revealing God and the perspicuity of nature is bound up in the fact that He voluntarily reveals. Both natural and special revelation would be impossible if God remained incomprehensible as He is in Himself (archetypal theology). Man cannot penetrate God as He is Himself - he cannot comprehend God. But created man may see clearly what is revealed clearly even if he does not see exhaustively. Man need not have exhaustive knowledge in order to know truly and certainly.
The Psalmist doesn't declare that the heavens possibly or probably declare the glory of God. Paul does not say that the wrath of God is probably revealed from heaven against all ungodliness and unrighteousness of men. Scripture takes the clarity of God's revelation for granted at every stage of human history. The God who speaks in Scripture cannot refer to anything that is not already authoritatively revelational of Himself for the evidence of His own existence. Everything exists that is His creation.
It is no easier for sinners to accept God in nature than it is for them to accept Him in Scripture. The two are inseparable in their clarity. We need the Holy Spirit to understand both. Man must be a Christian to study nature in a proper frame of mind no less than he needs the same understanding to properly apprehend the Scriptures. Modern man is truly darkened in the futility of his thinking because he does not begin by bowing the knee before God before he seeks to understand himself and the world around him.
