Athanasius.
Athanasius.
§ 84. Origen’s successor in the Alexandrian church was Athanasius, bishop of Alexandria, whom Epiphanius calls “the father of the upright faith”; Nazianzen, “the light of the Church”; Theodoret, “the bulwark of the truth” (Hist. eccles., bk. 1, c. 8). Emperor Leo classifies him “among the divinely eloquent men who were bright lights in the Church after the apostles and who brightened the firmament of the Church like stars with their deeds and writings” (Constit. 88). In Synopsis, vol. 2, p. 63, Athanasius mentions the same books that we, too, list in the canon and calls the rest 
[“not canonical”]. He says, “There are twenty-two canonical books in the Old Testament, equal to the number of Hebrew letters.” He does not include the Book of Esther; later, however, he adds that it belongs to some other canonical volume, perhaps to Ezra, by whom Isidore and others say that book was written.
