The book examines the religious issues of Jews, Christians and Muslims, as the most widespread and significant religious doctrines in resolving the spiritual crisis of the modern world. And of no small importance here is the truth that all spiritual beings, including man before the Fall, knew that God is One. The author G. Fedotov believes that this work will help many - with such increased violence and hatred between people - to resolve questions they have regarding the victory of good over evil. For the Lord, as stated in the creeds, looks at a person’s heart and his life’s deeds, and not at what religious denomination this believer belongs to!
