Abrahamic Religions Abrahamic Religions are all religious groups that can trace their origin from one spiritual source; Abraham. They collectively believe in the spiritual tradition identified with Abraham. Three of the major Abrahamic Religions include Christianity, Islam, and Judaism. The fact that they all trace and believe they originated from Abraham as the founding father, means there exists some similarities among them. However, it is worth noting that their eventual separations and adoption of different beliefs led to growing differences and rifts among them.
