The thinking of Joe, about conditions is valid and enables personal views, he is believing in as it is condition rather than modify it.
As we mentioned, Joe is only believer, so we can say that it is not necessary in beliefs to combine with mass number of believers. Pragmatism and some Eastern philosophy described lone believer religion.
Joe expressed some elements of religions, and missed many according to the definition of world religion. Joe showed epistemology and metaphysics of thought process, he confirms the faith with logics. But religious rituals, traditional values cannot be characterized by single person so that they are missing.
Joe needs, ethological views, more believers and thinkers as well as traditional views and rituals to be a world religion. Every religion in this world tried to help human and make them happy with less grieves, they evolved many ideas to do so, and here we can see that Joe also tried these steps but he need open thinking perspective rather than individual.
