The Monastic Letters of Saint Athanasius the Great
Translated, with an introduction, by Leslie W. Barnard
Athanasius' contribution to monastic life has been greatly undervalued. In these six letters, he is revealed as a wise spiritual guide and loving pastor, determined that monks receive orthodox teaching to avoid the pitfalls of arianism and encratism, and concerned for the welfare of the pachomian monasteries after the death of abbot Theodore.
