Everything 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[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 CassianNo just man suffices unto himself for the winning of justification. The divine mercy must always hold out a hand to his footsteps as they falter and almost stumble, and this is so because the weakness of his free will may cause him to lose balance, and if he falls he may perish forever.
John Cassian...we should realize that there are three sources for our thoughts - God, the devil, and ourselves.
John Cassian...works of piety and charity... are necessary in this present life for as long as inequality prevails. Their workings here would not be required were it not for the superabundant numbers of the poor, the needy, and the sick... As long as this inequity rages in the world, these good works will be necessary and valuable to anyone practicing them and they shall yield the reward of an everlasting inheritance to the man of good heart and concerned will.
John Cassian...when we abandon visible riches... it is strange goods and not our own that we are leaving. And this is so even if we boast that we acquired them through our own efforts or that they were passed on to us as an inheritance. I say nothing is ours except what is in our hearts, what belongs to our souls, what cannot be taken away by anyone.
