...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.
John Cassian[God] arranged that the boy Samuel should be chosen but instead of teaching him directly He had him turn once or twice to an old man. This youngster, to whom He had granted a direct encounter with Himself, had nevertheless to go for instruction to someone who had offended God, and all because that person was an old man. He decided that Samuel was most worthy of a high calling and yet He made him submit to the guidance of an old man so that once summoned to a divine ministry he might learn humility and might himself become for all the young a model of deference.
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 CassianGod is not only to be known in His blessed and incomprehensible being, for this is something which is reserved for His saints in the age to come. He is also known from the grandeur and beauty of His creatures, from His providence which governs the world day by day, from His righteousness and from wonders which He shows to His saints in each generation.
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
