... 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 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 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...the souls of the dead [are] not deprived of their intellectual faculties but... they also are not lacking in feelings such as hope and sadness, joy and fear. They already have a foretaste of what is in store for them after the general judgment. Nor does it happen, as some unbelievers would hold, that upon leaving this world they are turned to nothing. Actually they live more intensely and they concentrate more on the praises of God.
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 Cassian...we must first scrutinize thoroughly anything appearing in our hearts or any saying suggested to us. Has it come purified from the divine and heavenly fire of the Holy Spirit? Or does it lean toward Jewish superstition? Is its surface piety something which has come down from bloated worldly philosophy? We must examine this most carefully, doing as the apostle bids us: 'Do not believe in every spirit, but make sure to find out if spirits are from God'.
