Ascetic Life
Joseph was a strict ascetic of the Raithu desert, the monastic region on the western shore of the Sinai peninsula. Orthodox tradition relates that he attained such a high degree of perfection in the spiritual life that a light shone upon him while he prayed.
The synaxarion relates that he foretold the time of his death to his disciple Gelasius and then died in peace. His repose is recorded as having preceded the massacre of the Sinai Fathers.
