The well-known hierarch of the Russian Orthodox Church, preacher and theologian Metropolitan Veniamin (Fedchenkov) left a rich spiritual heritage - these are theological treatises, works on liturgy, apologetics, diary entries, artistic sketches and memories. Many of the works of the Lord of Benjamin are now published..... The proposed book “On Faith, Unbelief and Doubt” is a kind of biographical notes, which the saint himself called the confession of the heart ........ The Lord has revealed His way to the Lord, and He has revealed Himself to His people, and He has revealed Himself to them in a way that is pure and pure.............. He reflects on faith, on the ways leading to truth, on the place of man in this world and on the meaning of life, on the religion and significance of the Orthodox Church in the life of society and the individual, on temptations and doubts in the path of knowledge of God, on the Providence of God, on God’s grace and help ........ Metropolitan Benjamin speaks frankly about the hesitations and doubts that visited him when, after a simple-hearted child's faith, he wanted the faith "reasonable", when the mind was looking for evidence. Through numerous examples, Vladyka shows what is the attitude to the faith of famous scientists, public and state figures, writers, composers, artists, philosophers, theologians, religious figures and teachers of the Church. Surprising is the diversity of the personality of the Lord, striking his vast knowledge, rich spiritual experience, which he generously shares, helping the unbeliever to think, doubting to understand the errors, and the believer to strengthen himself in the hope of the Lord.
