In this section, Kierkegaard is arguing that God is totally different from human beings, and that theology isn't really about God: it's about people. We cannot mention a total difference because to talk about two things implies that there's a point of similarity or connection. At the very least, the speaker has to be able to conceptualize the characteristic or object that is different. This would be impossible were it not for some shared aspect. Kierkegaard argues that because God's nature is radically and completely alien from our own, it's impossible to make true statements about the nature of God. Any statements, such as "God is kind," or "God is all-knowing," is really simply a statement about how humans feel about God. Total differences are unmentionable because they are completely outside of our experience, as well as our vocabulary.
