The faiths of Judaism, Christianity, and Islam share a large number of theological beliefs and ethical principles. In fact, all three religions revere the Prophet Abraham and share more in common with each other than other religious traditions. Most importantly all three religions affirm the existence of one God, the Absolute and Infinite Reality continuously creating and sustaining all things in existence [for a rational and logical proof of this classical concept of God, click here]. The below chart presents 28 key theological beliefs of Abrahamic monotheistic theology in which the general Jewish, Christian and Muslim positions overlap greatly. It is hoped that readers will see how much commonality exists between the faiths of Judaism, Christianity and Islam and how this unites all Jews, Christians and Muslims in a spiritual bond of brotherhood.
