DaleSteve, you seem to have little idea of Christian unitarian theology. If you did, you’d know that we too believe in a self-revealing God, who by his spirit inspired the prophets and apostles, and through them the Bible, and who loved us so much that he sent his only Son as the best and last revelation of him.
But doesn’t Dale classify himself as a “humanitarian unitarian”? Here’s how he defines that category:
Some Christian unitarians past and present define their thesis as the claim that Christ has a human nature but not a divine nature – that is, they define a unitarian has what I have called a humanitarian unitarian (what is nowadays often called a “biblical unitarian”), understood as implying that Jesus existed no earlier than his conception.
So on that definition, in what sense is Jesus God’s “only Son”? Isn’t Dale just playing a shell-game?
Notice, too, that Dale says God sent Jesus, not to save us, but to merely reveal himself to us. Indeed, how could a merely human Jesus save us? How could he even save himself?
