... a Christian is quite certain to fall into the same sins which he condemns in another with merciless and inhuman severity, for 'a stern king will fall into misfortunes,' and 'one who stops his ears so as not to hear the weak, shall himself cry, and there shall be none to hear him' (Prov. 13:17; 21:13).
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 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 CassianAll of our holy fathers knew this and all with one accord teach that perfection in holiness can be achieved only through humility.
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 CassianIt is a bigger miracle to be patient and refrain from anger than it is to control the demons which fly through the air.
John CassianWhen the soul is solidly rooted in... peacefulness, when it is freed of the bonds of every carnal urge, when the unshaking thrust of the heart is toward the one supreme Good, then the words of the apostle will be fulfilled. 'Pray without ceasing,' he said (I Thes. 5:17). 'In every place lift up pure hands, with no anger and no rivalry' (I Tim 2:8). Sensibility is, so to speak, absorbed by this purity. It is reshaped in the likeness of the spiritual and the angelic so that all its dealings, all its activity will be prayer, utterly pure, utterly without tarnish.
