Jews and Judaism are the ones who brought the concept of monotheism to the world. One God created the entire world and all those who inhabit it. The first human being was created in His image and all those who came after carry within them this mark of divinity. Why did God begin the story of mankind by creating only one person?
The concept of equality we find in the Torah specifically and in Judaism generally is not an equality of wealth: Judaism is not communism. Nor is it an equality of power: Judaism is not anarchy. It is fundamentally an equality of dignity. We are all equal citizens in the nation whose sovereign is God.
