In this episode, Fr. Matthew returns to the Life of Moses by St Gregory of Nyssa, and examines a key passage in which the Saint compares the ascent of spiritual life to Moses's ascent of Mt. Sinai. What does it mean to ascend into "darkness," to converse with God "where the understanding does not reach"? And how does Moses's example reveal the way in which all the Fathers and Saints draw the whole Christian family into deeper communion with God?
