Analogy, negation, or “without asking how”: how can finite words say anything true of God?
Every year one of my students asks the question that underlies everything else: when we say "God is good" or "God knows", what do the words mean? If they mean what they mean of us, God becomes a large human being. If they mean something entirely different, we are saying nothing.
The three great medieval answers I teach are these.
Aquinas (Summa Theologiae I, q. 13): the names are said of God neither univocally nor purely equivocally, but by analogy. Goodness is in God first and in creatures derivatively; we know the perfection signified but not the divine mode of having it.
Maimonides (Guide of the Perplexed, Book I): we cannot positively describe God's essence at all. True statements are negations, which clear away what God is not, or descriptions of God's actions, which describe effects rather than the essence.
Al-Ashʿarī: affirm the attributes revelation gives, knowledge, power, even hand and face, as real, but bi-lā kayf, without asking how. Neither reduce them to metaphor nor imagine them like ours.
My own Igbo tradition has its say too. Many of our names for God describe what God does: Chineke is often glossed as "the God who creates". That sounds close to Maimonides' attributes of action.
My open question: which of these is most defensible today? Or is the honest position that each solves one problem by creating another?
