Yahwism is the religion practiced by the Hebrews and Israel during the pre-captivity Old Testament. Yahwists worshipped the one true God who calls himself Yahweh. After God came to Earth in incarnate form, Christianity was founded and succeeded the religion. While Yahwism has fundamentally the same doctrine as Christianity in only faith can provide Salvation the two are considered separate for chronology reasons. The term Yahwism is used in order to distinguish the worship of the one true God from the practice of polytheistic religions.
