Comparative religion is, by its analytical and, hopefully, objective view, one of the cornerstones of developing a global anthropology. While thousands of individual religious structures exist and have existed in the world, there are five that currently dominate the majority of world religious thought. It is the purpose of this paper to examine and compare three of those religions, Christianity, Buddhism and Judaism, on the nature or essence of God and the afterlife. The paper will take each issue individually and look at it through the view and practice of each of the three religions. Throughout, no value judgment will be made, only an effort to objectively discuss the form and function of each religion as it applies to each of the two mentioned topics.
