One of the most pressing issues of modern theology is the problem of interfaith relationships and especially the differences between Orthodoxy and Catholicism. Did the fall of Western Christians from the Orthodox Church stem from historical misunderstandings or was it caused by differences in worldview and spiritual image? life. This brochure provides answers to these questions. "Thus, throughout the history of the Christian Church, two modes of existence have persistently opposed each other: life in union with God, when the creature itself is adored by contact with Him; and life without God, when they believe in Him only theoretically, without participating in His life. These two antagonistic tendencies can be called, respectively, Orthodoxy and heterodoxy (in any of its forms). information: It should be noted that not all of the author’s statements can be agreed with. For example, at the end of the book he expresses the opinion that for Catholics who have alienated themselves from the Catholic tradition, who have gone beyond its boundaries, holiness is possible. This statement is contrary to the teachings of the Church, since holiness is possible only in the Church. Only by becoming members of the Church of Christ can one inherit salvation.
