Abstract
With this phenomenological contribution to Diadocus of Photicea’s anthropological theology, my main goal is to show how this saint, according to John Meyedorff’s nice words, has been “one of the main popularizers of the desert spirituality in the Byzantine world”. The spiritual experience of the taste of God is then in no way the privilege of the circle of initiates nor is it reserved for monks, who are sometimes idealized as athletes of God. What is at stake is the whole spiritual life, the whole daily journey of life, not only a provisional illuminated prayer-state. Diadochus therefore is still of interest for us today. We understand then how this experimental and experiential way does not include in the end a distinction between divine grace and human effort. Not that the parts played by human beings and God end up in a confusion, but, as we will see, since grace is given to the human being from baptism onward, it keeps on being more and more effective, as the human being practices, exercises (askesis), makes efforts (epimeleia), that is, namely, enters more and more into the invocation of the name of Jesus. So divine grace and human effort literally co-operate, work together, and spontaneously enter into a kind of danse in which they gradually become two in one.
