John Climacus the Righteous, author of The Divine Ladder of Ascent
This Saint gave himself over to the ascetical life from his early youth. Experienced both in the solitary life of the hermit and in the communal life of cenobitic monasticism, he was appointed Abbot of the Monastery at Mount Sinai and wrote a book containing thirty homilies on virtue. Each homily deals with one virtue, and progressing from those that deal with holy and righteous activity (praxis) unto those that deal with divine vision (theoria), they raise a man up as though by means of steps unto the height of Heaven. For this cause his work is called "The Ladder of Divine Ascent." The day he was made Abbot of Sinai, the Prophet Moses was seen giving commands to those who served at table. Saint John reposed in 603, at eighty years of age. See also the Fourth Sunday of the Fast.
Apolytikion in the Plagal of the Fourth Tone
With the rivers of your tears, you have made the barren desert fertile. Through sighs of sorrow from deep within you, your labors have borne fruit a hundred-fold. By your miracles you have become a light, shining upon the world. O John, our Holy Father, pray to Christ our God, to save our souls.
Kontakion in the First Tone
As ever-blooming fruits, thou dost offer the teachings of thy God-given book, O wise John, thou most blessed, while sweet'ning the hearts of all them that heed it with vigilance; for it is a ladder from the earth unto Heaven that conferreth glory on the souls that ascend it and honour thee faithfully.
