When we ask the question, “What is theology?” the word’s etymology offers us helpful insight. The word theology comes from the Greek and means “God-talk” (theos = “God”; logos = “word”). Hence, theology describes what we do: We talk about God. Better yet, we have conversations about God. Theology is communal; it belongs to the life of faith in the ongoing Christian community, stemming from the revelation of Jesus two-thousand years ago. (J.J. Mueller, “Introduction,” Theological Foundations, p. 1)
Why do I appreciate this definition of theology? First, while it is true that theology is “conversations about God,” it is equally true that theology is communal. We tend to neglect this important aspect as we do theology. Second, this definition makes it clear that this theology which is communal stems from “the revelation of Jesus,” thus making it Christ-exalting.
I commend this definition of theology.
