St. Mark the Ascetic: He who neglects action and depends on theoretcial knowledge . . .

Icon of St. Mark the Ascetic“He who neglects action and depends on theoretical knowledge holds a staff of reed instead of a double-edged sword; and when he confronts his enemies in time of war, ‘it will go into his hand, and pierce it’ (2 Kgs. 18:21), injecting its natural poison.”
