Em hotep,

All those who have studied the live of Avraham, know of the Sacrifice of his son. Depending on who you speak to, you are going to get differing responses for who that son was:

To the Jewish and Christian communities, it is Isaac, offered as a sacrifice because God directed this, but was then spared.
To the Muslim community, it is Ishmael, not Isaac who is offered.

But to the Orthodox Atenist Community, it is not so much who was offered as why he was offered that is the question. We believe that it was indeed, Isaac, who was offered as a sacrifice which is in agreement with the Jewish and Christian communities.

Where we diverge is the reason for the Sacrifice.

We teach that while Avraham is the biological father of Ishmael through Hagar. That Isaac is biological son of Thutmose the 4th (The Pharoah of that time) and Sarai. The reason for the sacrifice was not because God called Avraham to sacrifice Isaac but because Avraham knew and saw, as did all those around hiim, that Isaac did not have the features of Avraham, but had the features of Pharoah and Sarai. That it was evident that Avraham was not the biological father of Isaac.

Aten stops Avraham from following through with this sacrifice.

Ahmed Osman in his book "The Hebrew Pharoah of Egypt" states "...to slaughter your own son as a sacrifice to the Lord was not the practice in Arabia, Mesopotamia or even in Canaan at that time. Abraham's action can only be explained by the fact that he was trying to destroy a son who did not even look like him, who, according to the Talmud, 'all the people of the world suspected not to be his own son' - an heir to him who was, at the same time, an heir to the Pharaoh of Egypt".

May Aten bless you
