'As is the case with the most skilled physicians, who not only heal present ills but also confront future ones with shrewd expertise and forestall them with prescriptions and salutary potions, so also these true physicians of souls destroy, with a spiritual conference as with some heavenly medicine, maladies of the heart just as they are about to emerge, not allowing them to grow in the minds of young men but disclosing to them both the causes of the passions that threaten them and the means of acquiring health.'
John Cassian in Rebecca Konyndyk DeYoung, Glittering Vices: A New Look at the Seven Deadly Sins and their Remedies, p.40.
