What city was judaism founded in?

Answer 1

There are three answers. One is in the city of Ur in Babylonia, since according to tradition it was there that the young Abraham first repudiated the ubiquitous idolatry and began teaching others about the One God.

The second, more correct answer is the Holy Land, since it was there that Abraham lived most of his life, made a covenant with God (Genesis ch.15), and raised a family to be the center of carrying on his traditions (Genesis 18:19).

Thirdly, Judaism as a binding, permanent entity, was set forth between God and the Israelite nation descended from Abraham, Isaac and Jacob at Mount Sinai in the time of Moses (Exodus ch.19, ch.24, and 34:27).

Answer 2

Abraham first recognized the falsehood of idolatry in Ur, but spent most of his life and did most of his work in Canaan.

Answer 3

Jerusalem is the symbolic center of Judaism, but since the destruction of the Temple in Jerusalem by the Imperial Roman Army in the year 70, Judaism has not been dependent on Jerusalem as a center of Jewish thought. At various times since the year 70, the center of Jewish thought has moved, Tiberias, Babylon, Seville (Spain), Worms (Germany), Safed (then Palestine) and Vilna (Lithuania) have all been religious centers of Judaism.
