No 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 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.
John CassianNo other virtue makes man more equal to the angels, than the imitation of their way of life.
John CassianWhen we say 'hallowed be Your name' to God what we are really saying is 'Father, make us such as deserve knowledge and understanding of how holy You are, or at least let Your holiness shine forth in the spiritual lives we lead.' And this surely happens as men see our good works and glorify our Father in heaven.
John Cassian... 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).
