On the surface, it seems that science and the internal clarity of Scripture have not much to do with each other. How does science, that activity whereby humans build theories to explain and predict natural and social phenomena, connect to the theological notion that Scripture is clear in and of itself? How does science link to Scriptural perspicuity, to the notion that while we may not deeply understand Scripture, it nonetheless retains an objectively understandable meaning? To connect the previously unconnectable is always dangerous, for there are reasons why they have not previously been linked.
Yet in the spirit of exploration, I wish today briefly to think their linking; I wish to suggest that they can be connected, and that linking them entails a rather robust Trinitarian perspective. Before setting about exploring the being of their linking, however, we must understand what it is that we are trying to connect. This demands we say something both about the nature of science and Scriptural perspicuity. We shall deal with the latter first, consider the former second, and conclude by connecting the former to the latter.
Accordingly, while we may be ignorant of the vocabulary and grammar of Scripture, knowledge of Scripture’s subject matter is possible, e.g, knowledge of the Trinity, the incarnation, and the work of Christ. “The subject matter of the Scriptures, therefore, is all quite accessible, even though some texts are still obscure owing to our ignorance of their terms.”(2) Luther goes further, claiming of those who do not grasp Scripture’s clarity that a “veil lies over their minds.” The problem is the stubbornness of the interpreter:
"With similar temerity a man might veil his own eyes or go out of the light into the darkness and hide himself, and then blame the sun and the day for being obscure. Let miserable men, therefore, stop imputing with blasphemous perversity the darkness and obscurity of their own hearts to the wholly clear Scriptures of God."(3)
The clarity of Scripture does not entail we know the nature of divine things and how it is that they are the way they are; it only entails that we know divine things are in a particular way: “Scripture simply confesses the trinity of God and the humanity of Christ and the unforgivable sin, and there is nothing here of obscurity or ambiguity. But how these things can be, Scripture does not say (as you imagine), nor is it necessary to know.”(4)
Luther has made a couple of important distinctions in these passages. Firstly, he apparently wants to distinguish the sentences of theological language from the propositions expressed by those sentences. While the words and grammar of the language can be obscure, what is stated by it is clear - - if one approaches the text with sincerity.
For Luther, inheriting the semantic theory of the late middle ages, words and sentences signify, that is, they cause the mind to think about certain things. Luther is merely claiming that there is no ambiguity in what the sentences of Scripture cause the mind to think about.
Secondly, Luther appears to distinguish the clarity of the propositions from the putative states of affairs to which these propositions refer. While one might know what is asserted by the proposition, one cannot know exactly how it is that what is asserted obtains or can obtain. In the semantic theory of the day, Luther is claiming that while the supposition of Scriptural language makes true that language, it is not easy to grasp how what is supposited can obtain. For instance, while the statement ‘God is Triune’ has a clearly signified sense and a definite reference making it true - - ‘God is Triune’ is true if and only that which is signified by ‘God’ is a member of the class of all things signified by ‘Triune’ - - it is not routinely possible to picture or grasp the natures of these objects signified by ‘God’ and ‘Triune’.
Finally, Luther distinguishes external obscurity and clarity from internal obscurity and clarity. The first pertains to the external ministry of the Word; the second concerns the understanding of the heart. Concerning the latter Luther writes:
"If you speak of the internal clarity, no man perceives one iota of what is in the Scriptures unless he has the Spirit of God. All men have a darkened heart, so that even if they can recite everything in Scripture, and know how to quote it, yet they apprehend and truly understand nothing of it. They neither believe in God, nor that they themselves are creatures of God, nor anything else . . ."(5)
The “internal clarity” of Scripture is concerned with the salvific significance of those things signified and it is given only via the Holy Spirit. Luther distinguishes this internal understanding from the external clarity:
"For the Spirit is required for the understanding of Scripture, both as a whole and in any part of it. If, on the other hand, you speak of the external clarity, nothing at all is left obscure or ambiguous, but everything there is in the Scriptures has been brought out by the Word into the most definite light, and published to all the world."(6)
A century later and in words deeply reminiscent of Luther, the great Lutheran dogmatician Johann Gerhard writes:
"If you speak of the internal clearness, no man understands a single iota of the scriptures by the natural powers of his own mind, unless he have the Spirit of God; all have obscure hearts. The Holy Spirit is required for the understanding of the whole of Scripture and all of its parts."(7)
Externally Scripture is clear, though human beings often (maybe mostly) find it obscure; inwardly it is obscure unless the Holy Spirit “lifts the veil” and facilitates its apprehension. The external Word is thus a necessary condition for the text’s external clarity, while the presence of the Holy Spirit is the necessary condition for its internal clarity.
At play in this tradition of reflection Scriptural clarity is the notion of the “hermeneutical circle” where the parts interpret the whole and the whole interprets the parts. The 17th century dogmatician Quenstedt writes:
"The more obscure passages, which need explanation, can and should be explained by other passages that are more clear, and thus the scripture itself furnishes an interpretation of the more obscure expression when a comparison of these is made with those that are more clear; so the Scripture is explained by Scripture."(8)
But, this hermeneutical circle again presupposes the agency of the Holy Spirit:
"From no other source than the sacred scriptures themselves can a certain and infallible interpretation of scripture be known. For scripture itself, or rather the Holy Spirit speaking in scriptures or through it, is the legitimate and independent interpreter of itself."(9)
The internal clarity of Scripture is thus supposed to steer between the Scylla of the external authority of a teaching magisterium and the Charybdis of internal private “enthusiasm.” By asserting it, Luther and the Reformers put an end to the fanciful interpretations of both the tradition’s fourfold method of scriptural interpretation and the privately “enthused” interpreter. The problem is that both alternatives could always claim to discern a deeper “spiritual truth” behind the shallow vulgar letter of the biblical text, a “truth” that Luther and his colleagues recognized is likely merely the result of the wishful projection of sinful man and woman.
In conclusion, we must point out that the internal clarity of Scripture is profoundly tied to the notion of objectivity: Indeed, the necessary condition of Scriptural clarity is semantic objectivity. While we can perhaps model the sentences of Scripture, we cannot grasp how these models correspond to the actual divine world. For this the Holy Spirit is needed, for it is His presence that makes possible understanding what is clearly asserted in the text. The Word of the text, externally clear and objective, becomes internally clear as well when the Holy Spirit grants internal appropriation of that external Word. In other words, the model of the sentences of Scripture is now grasped as characteristic of how the divine is, especially how the divine is with respect to us.
