The author's first book reflects the themes most characteristic of the thoughts of the Sovereign (doctor, natural scientist by education): matter and spirit, life and death, faith and doubt, man in relationship with God, their meeting, the ways of God in the world. The book is equipped with an extensive introductory article, photographs, and numerous comments. The book is intended for the widest circle of readers: not only Orthodox, but everyone who wants and is ready to hear what the Orthodox Church says to a modern person.
