There are five oceans on earth. Each of them is tied to a specific part of the world. But there is a sixth ocean - the ocean of faith, the ocean of God. Its geographical location is in the heart of man. The book is about this ocean. It is like a drop reflecting the ocean, spread out in time and space. What did the young monk, the future Patriarch, think, looking forward to sending the ship to Japan, and what did he see in Japan? How did the girl Vera from a simple family become the nun Hermogena, whom many priests, and above all her spiritual father, spoke of as a truly spiritually gifted old woman? How did a plywood cross save a priest in a terrible time? How did Russian pilgrims celebrate Easter and Christmas in Jerusalem? What do Orthodox Africans in Kenya eat for the meal after the liturgy? The book concerns different times and different continents, here a single space-time of Orthodox Christianity was formed, an ocean in which the mysterious island of the Church rises. The book is recommended by the Publishing Council of the Russian Orthodox Church.
