I cannot stress this enough.
When we say things like “God is love” or “God is peace”, we are defining what we mean by the word, “god”. What we cannot be and are not doing is saying that “god” is what defines either love or peace. That’s because “god” has no inherent meaning aside from those meanings we choose to use in order to give it any meaning at all. God, if such a thing exists, isn’t either love or peace because God transcends. Love and peace would then only stand to be effects by which we know God. But if that’s the case, one may completely dismiss the idea of God because the ineffable, the transcendent, has no causal proposition to any effects. In other words, no one in their right mind would find it meaningful to say “Love is love” or “Peace is peace” or that “Love is the cause of love” and “Peace is the cause of peace.” And so is the fate with any signifier we’d use for God.
“God” literally is exactly what we say He is, exactly what we claim He is; only He really isn’t at all in any epistemological sense; “God” is an idea and, God may not exist at all, proving the meaning of “god” and the meaningfulness of god-talk isn’t tied to God.
Just a thought.
