 Judaism also universally recognizes the Biblical Covenant between God and the Patriarch Abraham as well as the additional aspects of the Covenant revealed to Moses, who is considered Judaism's greatest prophet.In the Mishnah, a core text of Rabbinic Judaism, acceptance of the Divine origins of this covenant is considered an essential aspect of Judaism and those who reject the Covenant forfeit their share in the World to Come.Establishing the core tenets of Judaism in the modern era is even more difficult, given the number and diversity of the contemporary Jewish denominations.
