Wow, Ghosty, that was a really good response. Thank you.
The Judeo-Christian claim is simply that the “one God” revealed Himself uniquely to Moses and the Jewish people, culminating in the Incarnation and the New Covenant, and that is something that is utterly unaffected by Akenaten coming along before Moses. Moses wasn’t the first believer, nor was even Abraham, they were just specially chosen.
And the best answer, IMO. Everything my post detailed, Brendan’s post states plainly.
Peace and God bless!
