The doctrine of analogy aims to answer the question of how we can speak of an infinite God who transcends creaturely reality, thought, and language. Instead of saying words apply in exactly the same way to God and creatures (univocity), or that words apply in completely different ways to God and creatures (equivocity), we say they apply analogically in order to capture the reality of similarity and distinction.
Now, there are a number of charges to be made against analogy, but one that occurs with some frequency is that it is an unbiblical doctrine that theologians have come up with under the pressure of an all-too-philosophical theism and not the revelation of Scripture.
And yet, it seems that something like analogy is precisely what the revelation of Isaiah, especially the Lord’s speeches in 40-55, presses us towards. Consider the Lord’s extreme declarations of incomparability:
To whom then will you compare me ?” (40:25):
“Is there any god besides me? There is no rock; I know not one.” (44:8)
“I am the Lord, and there is no other.” (45:18)
“I am God, and there is no other; I am God, and there is no one like me.” (46:9)
“I am He; I am the first, and I am the last.” (48:12)
The Lord declares himself to be without peer, utterly unique, compared to whom the agency of kings, nations, and other so-called gods is nothing at all (41:24). Who else creates light or darkness, weal or woe? (45:6-7) No one and nothing.
And yet, and yet, as Frederick Gaiser points out in his article, “To Whom Then Will You Compare Me? Agency in Second Isaiah,” (Word & World Volume XIX, Number 2 Spring 1999), God is not strictly or absolutely incomparable if that means we can’t use human language and experience to refer to him at all. In fact, “The prophet will require a wealth of images to justice to the wonder of the God he proclaims.”
In his prophecy, God deploys a “variety of images to bear witness to his person and work” drawn “from the realm of creation and human life.” And this is fitting “because the prophet’s question about a “likeness” for Yahweh uses the same term used for the human in Genesis, created in the “likeness of God” (Gen. 1:26).”
Among other things, God is portrayed as redeemer (41:14), savior (43:3), maker or potter (45:9-10), rock (44:8), warrior (42:13), woman in labor (42:14), shepherd (40:11), friend (41:8), helper (41:10), lover (43:4; cf. 49:169), rear guard (52:12), mother (45:10), father (45:10),10 nurse (49:15), husband, hawker (55:l).
Gaiser adds, “not only do these images work, they are apparently necessary–and precisely in their abundance.” The paradox seems to be that without these images and comparisons drawn from creation, we would not be able to express the incomparability of the Lord.
He calls attention to a key description of the Lord after the acclamation, “Here is your God!” (40:9):
See, the Lord God comes with might,
and his arm rules for him;
his reward is with him,
and his recompense before him.
He will feed his flock like a shepherd;
he will gather the lambs in his arms,
and carry them in his bosom,
and gently lead the mother sheep. (40:10-11)
The Lord is described as a warrior (10) and a shepherd (11). With the same arm he strikes down the foe and “gather the lambs” (11). “Despite the differing pictures, they portray one God. It is not that sometimes God is strong and sometimes God is tender: God’s strength is God’s tenderness, God’s tenderness is also God’s strength. In bringing these images together, the warrior image especially is sharply redefined.” (Simplicity alert!) Gaiser continues to note comparison after comparison, juxtapositions, and surprising redefinitions, which keep us from understanding these comparisons as operating in a simply univocal fashion.
We could keep going, but important point I think we ought to see here is that against a radical skepticism, God is able to take up language from the created realm as a vehicle of revelation. They point us to the truth of God. And, at the same time, their bewildering and overpowering variety attests to their insufficiency and inadequacy at capturing his infinitely more glorious essence.
All of which is to say, while the formal fine-tuning of the doctrine of analogy may be influenced and guided by philosophical considerations, its instinct is a thoroughly biblical one.
Soli Deo Gloria
There is no doubt that analogical knowledge is the way to go, but beyond that, to move from the reality of analogy to the analogia entis is quite the step. Is it really a fine-tuning or is there something more going on in regard to how we conceive of a theological ontology/epistemology to begin with? The examples provided from Isaiah are all given from within God’s covenanted Self-revelation; reading Christianly, revelation that is encompassed by the domain of his life in Christ (Lk 24 etc). We could make the argument that the analogy, rather than entis is better understood as fide/relationis, since the basis for the analogy itself, even in Isaiah, is presupposed by the relationship Yahweh has with us, proleptically, in the Son; in and through the faith of Christ. Within this framework these analogies take on significance as comparisons that have significance within a relation of faith between the object-subject being known and the subjects coming to know this object-subject.
