Fasts and vigils, the study of Scripture, renouncing possessions and everything worldly are not in themselves perfection, as we have said; theyare its tools. For perfection is not to be found in them; it is acquired through them. It is useless, therefore, to boast of our fasting, vigils, poverty, and reading of Scripture when we have not achieved the love of God and our fellow men. Whoever has achieved love has God within himself and his intellect is always with God.
John Cassian...whoever is guided solely by his own judgment and decision will never climb up to the summit of perfection and will not fail to be the victim of the devil's ruinous power to delude.
John CassianActually, all gifts have been given for reasons of temporal use and need and they will surely pass away at the end of the present dispensation. Love, however, will never be cut off. It works in us and for us, and not simply in this life. For when the burden of physical need has been laid aside in the time to come it will endure, more effectively, more excellently, forever unfailing, clinging to God with more fire and zeal through all the length of incorruption.
John CassianIt is impossible for the mind to remain undisturbed by thoughts, but anyone serious about the matter can certainly permit them entry or drive them away, and although their origin does not lie entirely under our control we can choose to approve of them and to adopt them.
John CassianThe second request of the very pure soul is to see the coming of the Father's kingdom (cf. Mt. 6:10). What this means first of all is that each day Christ should reign among holy men. And this happens when the devil's power has been driven out of our hearts through the expulsion of sinful foulness and when God has begun to reign within us amid the good odors of virtue. With fornication vanquished, chastity rules; with anger overcome, peace is king; with pride under foot, humility is sovereign.
John CassianIt is by means of these that we attain perfect love, through the grace and compassion of our Lord Jesus Christ, to whom be glory through all the ages. Amen.
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
