"We shall be blessed with clear vision if we keep our eyes fixed on Christ, for he, as Paul teaches, is our head, and there is in him no shadow of evil...As no darkness can be seen by anyone surrounded by light, so no trivialities can capture the attention of anyone who has his eyes on Christ. The man who keeps his eyes upon head and origin of all the universe has them on virtue in all its perfection: he has them on truth, on justice, on immortality and on everything else that is good, for Christ is goodness itself."
