Men seized of the urge to have a knowledge of God and to be pure in mind devote all their gathered energies to this one task. While they still live in the corruption of the flesh they give themselves to that service in which they will persevere when the corruption has been laid aside. And already they come in sight of what the Lord and Savior held out when He said, 'Blessed are the clean of heart, for they will see God' (Mt. 5:8).
John Cassian...unless the grace of God comes to the help of our frailty, to protect and defend it, no man can withstand the insidious onslaughts of the enemy nor can he damp down or hold in check the fevers which burn in our flesh with nature's fire.
John CassianIf you want to correct your brother when he is doing wrong? you must keep yourself calm; otherwise you yourself may catch the sickness you are seeking to cure and you may find that the words of the Gospel now apply to you? 'Why do you look at the speck of dust in your brother's eye, and not notice the rafter in your own eye?'
John CassianIf you wish to attain to true knowledge of the Scriptures, hasten to acquire first an unshakeable humility of heart. That alone will lead you, not to the knowledge that puffs up, but to that which enlightens, by the perfecting of love.
John CassianEverything we do, our every objective, must be undertaken for the sake of... purity of heart... we must practice the reading of the Scripture, together with all the other virtuous activities... to hold our hearts free of the harm of every dangerous passion and in order to rise step by step to the high point of love.
John Cassian... when death has been brought upon a saint, we ought not to think that an evil has happened to him but a thing indifferent; which is an evil to a wicked man, while to the good it is rest and freedom from evils. 'For death is rest to a man whose way is hidden' (Job 3:23 LXX). And so a good man does not suffer any loss from it.
John Cassian...just as the edifice of all the virtues strives upward toward perfect prayer so will all these virtues be neither sturdy nor enduring unless they are drawn firmly together by the crown of prayer. This endless, unstirring calm of prayer... can neither be achieved nor consummated without these virtues. And likewise virtues are the prerequisite foundation of prayer and cannot be effected without it.
