Patriarch Kallistos I as a spiritual author*

The article is dedicated to Patriarch Kallistos I as a spiritual author. First and foremost, he shows himself to be a faithful interpreter of the established tradition, with an evident predilection for certain authors and works, particularly John Climacus. On the other hand, the presence and influence of the teachings of his master, Gregory of Sinai are undoubtedly recognizable. Kallistos amplified and took up some elements, while he reorganized, or at least apparently ignored others absolutely central (prayer techniques). Kallistos' work is also an important, and almost isolated, testimony to the continuity of composition of ascetical-spiritual texts in the first generation of the school of Gregory the Sinaite. The appendix presents the edition, accompanied by the translation of two discourses of Kallistos I on submission and obedience.
