Wisdom (sapientia) is predicated univocally only of God inasmuch as God alone is truly wise — and therefore is predicated equivocally of human beings. Therefore, when predicated of God, wisdom does not indicate a genus of wise things of which God is one. The divine sapientia is a proper attribute of God: it is divine wisdom in the sense of being identical with the divine essence in its utter simplicity and its freedom from all composition. The theologia archetypa, then, is God himself, the identity of self and self-knowledge in the absolutely and essentially wise God.
(Richard Muller, Post Reformation Reformed Dogmatics: Prolegomena to Theology, p.231)
And that ought to show that the doctrine of divine simplicity is a very fruitful ground for meditation.
