Eldership and Shamordino
The Shamordino convent, founded by Elder Ambrose roughly eight miles from Optina, came under Joseph's care as its spiritual director and confessor; he is recorded as visiting twice yearly during the Apostles' and Dormition Fasts.
As an elder he was noted for humility and sparse speech, often citing the counsel of Father Ambrose rather than speaking on his own authority. Sources describe him as devoted to the unceasing prayer of the heart and grounded in the Philokalia and patristic writings.
