Wherefore a monk's whole attention should thus be fixed on one point, and the rise and circle of all his thoughts be vigorously restricted to it; viz., to the recollection of God, as when a man, who is anxious to raise on high a vault of a round arch, must constantly draw a line round from its exact centre, and in accordance with the sure standard it gives discover by the laws of building all the evenness and roundness required.
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 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).
John Cassian...we know that God arranges the opportunities for salvation in different ways. Our situation is that we respond eagerly or in a laggardly manner to these opportunities made available by God to us. God made the call come out of your homeland; Abraham by coming out was exercising obedience. There was the instruction come into the land; it was done, and that was the work of obedience. But the addition which I shall show you has to do with the grace of God, who gave a command - and a promise.
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 CassianPerfection... is clearly not achieved simply by being naked, by the lack of wealth or by the rejection of honors, unless there is also that love whose ingredients the apostle described (cf. I Cor. 13) and which is to be found solely in purity of heart. Not to be jealous, not to be puffed up, not to act heedlessly, not to seek what does not belong to one, not to rejoice over some injustice, not to plan evil - what is this and its like if not the continuous offering to God of the heart that is perfect and truly pure, a heart kept free of all disturbance?
