A rough comparison of Judaism and Christianity might be like the relationship of the eastern religions of Hinduism and Buddhism. Judaism would be like Hinduism and Christianity would be like Buddhism. Both religions, Buddhism and Christianity rely on an already established religious base, Judaism and Hinduism, and emphasis the role of a single person, Buddha and Jesus. Both Christianity and Judaism have the same base. The center of the Old Testament covenant was Yahweh and his people, while the heart of the Christian message was around Jesus of Nazareth, the Christ, who was Jewish.
