So the NY Times posts an article in it's Sunday Magazine about Freud and religion wherein we find the following:
Freud also said that monotheism was not a Jewish but an Egyptian invention, descending from the cult of the Egyptian sun god Aton.
This is a popular concept and is based on the short lived religious upheaval by Akhenaten who attempted to wrest control from the priests of Amen. Important distinction because...
About two-thirds of the way into the volume, he makes a point that is simple and rather profound — the sort of point that Freud at his best excels in making. Judaism’s distinction as a faith, he says, comes from its commitment to belief in an invisible God, and from this commitment, many consequential things follow. Freud argues that taking God into the mind enriches the individual immeasurably. The ability to believe in an internal, invisible God vastly improves people’s capacity for abstraction.
See we need to get back to that Amen. See the supreme God in Khemetic (Egyptian) religion was Amen-Ra. Ra being God and Amen meaning hidden one. So in fact the Egyptians are the inventors of the "invisible" God and Judaism merely bit the concept. The problem with the latter religion, including Christianity and Islam is the failure to understand the concept of symbolism. All those "idols" are not 'gods" they are representative of some natural force. They are points of focus no less than people who wear crosses don'r actually worship the cross.
