Abstract: The subject of this research is the historical evolution of the three world religions – Buddhism, Christianity, and Islam. The author analyzed the development of these religions based on the model of religious cycle, which in his opinion, is common to the majority of historical religions, in other words, religious systems created after the invention of writing. In accordance with the author’s concept, each of the aforementioned religion has gone through six stages of development: initial, orthodox, classical, reformist, critical, and post-critical; as well as two types of crises – structural and system. The three methods are used in the course of this study: historical, comparative, and method of ascension from abstract to concrete. The main conclusion of the conducted research consists in the statement on the functional identity of historical development of Buddhism, Christianity, and Islam regardless of their doctrine of ritual practice. Author’s special contribution is defined by formulation of the abstract model of religious cycle that he applies to the evolution of the aforementioned religions.
