A “Christian” is a human person who believes that Jesus, the Christ, is God, Lord, Savior, Redeemer ...
But neither the Father, nor the Son, nor the Holy Ghost, is a human person (they’re divine persons).
Therefore, God is not a Christian.
Which would mean they are nouns, not "verbs." Also in this same message he says "God is not a being."
Which is why I posed the question - are these progressives even theists?
