...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 CassianWe are often indifferent to our brethren who are distressed or upset, on the grounds that they are in this state through no fault of ours. The Doctor of souls, however, wishing to root out the soul's excuses from the heart, tells us to leave our gift and to be reconciled not only if we happen to be upset by our brother, but also if he is upset by us, whether justly or unjustly; only when we have healed the breach through our apology should we offer our gift.
John CassianThe thief who received the kingdom of heaven, though not as the reward of virtue, is a true witness to the fact that salvation is ours through the grace and mercy of God.
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 CassianNo structure of virtue can possibly be raised in our soul unless, first, the foundations of true humility are laid in our heart.
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?
