The Concept of Light in Scripture and Theology
As we reflect upon the declaration that âGod is light,â we are seeking to answer the question: Who is God? Who is this One who is light in himself, and from himself shines forth his light to his human creatures? A trinitarian theology of divine light, we shall soon see, points to this radiant identity of God the Father, Son, and Holy Spirit. And such a radiant identity is, further, to be regarded with respect to the divine distanceââhe is nothing like the light with which we are acquaintedââand with regard to the divine approachââHe may most properly be termed lightââin Godâs turning towards human creatures in the darkness of sin and death.
In speaking of the light of God, this first chapter seeks to give an initial grounding to a trinitarian theology of divine light by marking a conceptual boundary. This will be primarily accomplished in three ways: first, by a survey of several scriptural instances of the concept of light; second, by a brief examination of the dogmatic gloss upon these scriptural instances from Nicene trinitarian theology; and third, by an inquiry into the âcontingentâ misuse of the concept of light.
The Scriptural Foundation of the Concept of Light
The basis for a trinitarian theology of divine light is found in reading the prophets and apostles of Holy Scripture. That is, the guiding action for our study is straightforward: a âconversation in which One speaks [i.e., God through Scripture] and the other listens [i.e., the reader of Scripture].â Of course, listening to scriptural witness is necessary for our present exegetical context: tracing the biblical use of light as the âbest figure or representation of the Divine Majesty.â Yet before giving a select reading or, indeed, listening to several scriptures, we must at once caution that each instance of the image of âlightâ or âgloryâ in the biblical canon is situated in a unique context and locus. It is not our aim here, therefore, to overlook such contexts; rather, again, we seek to listen to the scriptural witness of the light of God so as to provide the necessary boundary for the forthcoming theological movements of our study. We will initially retrieve several major themes about the concept of light by tracing three vital scriptural instancesânamely, in the book of Genesis, the Synoptic Gospels, and various Johannine materialsâbefore moving to examine how such scriptural occurrences might inform our way forward in this study.
âLightâ in Genesis
We might first say that the standard text for any listening to the biblical occurrence of the image of light is often found in the narrative of the creation account in the book of Genesis. It is here that we find a clear instance of God and his creation, the creative speech of God, and the creation of light by divine speech. That is, we find at the head of the Pentateuch the astounding fact that even before making the heavenly luminaries (Gen 1:14â15), in the primal chaos of darkness God spoke and created light.
We hear in this principal passage of how God has surrounded himself with light, the âornament and glory of the whole visible creation.â By this first creative utterance of v. 3, we see that created light is not itself God but a âcreatureâ and an âornamentâ of Godâs creative utterance. That is, this ornament of Godâs creative power rests wholly on the fact that God, by the power of his Word, spoke light into existence and âsaw that it was goodâ (v. 4). This means that God wills to uphold and preserve this light. The fact that God âsawâ his work, that he continues to see it, keeps the world from plummeting into chaos (v. 2). This âseeingâ is followed by an allusion to the existence of darkness; but just as it does not state that God created darkness, so it does not state that he saw that this darkness was good. This can be said of light onlyâthat is, of the light that was set apart from darkness. In finding light worthy of this separation, God sees how the light is good, namely, that it is good as his symbol and ornament; that it is a bulwark against darkness and confusion; and that it forms Godâs âbasic principle of âseparation.ââ
This initial divine utterance, therefore, unmistakably differentiates between that radiant identity of God as Creator over against any so-called âgod of lightââor, indeed, between the light spoken of here and an admittedly close hermeneutical connection with the Son of God. Consequently, any commingling of lightâthis âfirstborn commandmentââwith a divinization of light, or with the Word itself, is wholly unwarranted. âLight is not somehow an overflow of the essence of deity,â says von Rad, âbut rather an object . . . of Godâs creation.â Created by God, light therefore not only points to the radiant identity of God over creation, âthe absolute distance between Creator and ...
