The article traces the formation of the mystical experience of Nikolai Sergeevich Arseniev (1888–1977) on the basis of the memoir book “Gifts and Encounters of the Life Path” (1974), and the stages of his consideration of biblical studies. The analysis of Arseniev’s exegetical work “The Religious Experience of the Apostle Paul” (1935) is proposed. He was one of the Russian thinkers in whose writings the Holy Scripture occupied a central place, and almost all of his religious ideas grew out of New Testament books, and biblical concepts.
