Clement of Alexandria : "The opened eyes of the blind" means [Christ] provided clear knowledge of the Father through the Son. — The Stromata Book 1 Theodoret of Cyrus : He calls "blind" here those who are impaired in their intellectual vision; he calls the same people imprisoned by the bonds of sin and held by the darkness of error. After having delivered them from the murk of ignorance and having broken the bonds of sin, he has led them to the light of truth. — COMMENTARY ON Isaiah 12:42.7
