Jefferson had some glimmers of greatness in his own way, but theologian he was not!!
Jefferson’s intention was to draw the readers focus on certain things, it was not a rejection of miracles and you can see in the letter of his I posted where he is quite happy with the Bible, just not happy with what men added after it.
You asked what what different from 1st and 4th century beliefs about the nature of God and I gave you the info. No need to get defensive about it.
