Simeon the New Theologian (949: Galatia - 1022: Chrysopolis) is a monk, theologian, mystic and writer of “Hymns” (poetic spiritual verses), one of the founders of the tradition of hesychasm. Along with two great theologians of the Church - John the Theologian and Gregory the Theologian, Simeon was awarded the name New Theologian. Revered by the Orthodox Church in the person of the saint, the memory is celebrated on March 12 (according to the Julian calendar). Formulating Simeon's thought in the shortest possible way, we can say that the main thing for him in the Christian faith is personal, direct experience of communion with God. In this he continues the tradition of Rev. Macarius the Great. Simeon affirms the possibility, based on his experience, that God reveals himself to man and becomes visible, and not in a future life, but already on earth. Mystical philosophy Rev. Simeon anticipated the hesychasm of the 14th century. Reprint edition from the book of 1892.
