A clear rule for self-control handed down by the Fathers is this: stop eating while still hungry and do not continue until you are satisfied.
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 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 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.
John CassianIt is not our free will but 'it is the Lord who sets the captive free' (Ps. 145:7). It is not our own virtue but 'it is the Lord who lifts up those who were laid low' (Ps. 145:8). It is not application to reading but 'it is the Lord who gives light to the blind' (Ps. 145:8). It is not our cautiousness but 'it is the Lord who protects the stranger' (Ps. 145:9). It is not our endurance but 'it is the Lord who raises or gives support to the fallen' (Ps. 144:14).
