The Jewish Year begins soon. The New Year will be 5767. The Hebrews have been saying the word 'God' longer than any other faith of Abraham.
Judaism began the belief in one god. Monotheism.
Judaism is not a schism of any belief system prior to it. Monotheism grew out of slavery.
The 'cornerstone' to the Jewish faith are the stone tablets brought by Moses to his people as they were presented to him by God.
The Hebrews believe in the Ten Commandments.
