Serbian ruler Stephen the First Crowned (1196–1227) interpolates in The Life of Saint Symeon the episode of his brother’s embracing of the monastic life in the ninth chapter of his writing. In this manner he connects the spiritual experience of his father with the similar experience of his brother, whose escape from the political power to the Mount Athos triggers identical behaviour of his father. In depicting of this episode, the author exploits numerous allusions to motifs, expressions and terms characteristic of the Johannine literature within the corpus of the New Testament books. The intention of the author is to present Rastko Nemanjic’s leaving the world in light of the Johannine apocalypticism, as the perfect example of following Christ, who also departed from the world (Jn 13, 1). The immediate reason for Rastko’s departure is the apocalyptic vision of the Jerusalem above of his father, Stefan Nemanja. This vision incites in Rastko’s soul yearning for the monastic life at the Mount Athos, which is articulated in his prayer to Christ in terms of the Johannine „high” christology, especially from the Prologue of the Fourth Gospel.
