Hieromonk Seraphim Rose 1934-1982
On grace, for example, the Egyptian Father St. Paisius the Great failed to recognize his own disciple after he returned from a brief trip to Alexandria. It turned out that the disciple had met a heretic and had agreed with him that “perhaps” some Orthodox dogma was not true after all, and grace left him, and this was literally seen by his elder, so real is grace, and so carefully must it be kept. (Letters From Father Seraphim, p. 24. Letter August 16/29, 1971)
