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 CassianLet everybody know this. He shall be assigned to the place and to the service to which he gave and devoted himself in this life and he can be sure that in eternity he will have as his lot the service and the companionship which he preferred in this life. This is what the Lord means when He says, 'If anyone is my servant let him follow Me and where I am he will be there as my servant' (Jn. 12:26).
John CassianWe must, with God's help, eradicate the deadly poison of the demon of anger from the depths of our souls. So long as he dwells in our hearts and blinds the eyes of the heart with his somber disorders, we can neither discriminate what is for our good, nor achieve spiritual knowledge, nor fulfill our good intentions, nor participate in true life; and our intellect will remain impervious to the contemplation of the true, divine light; for it is written, 'Man's anger does not bring about the righteousness of God' (Jms. 1:20).
John CassianTrue spiritual knowledge has sometimes flourished most grandly in some who were without eloquence and almost illiterate. And this is very clearly shown by the case of the Apostles and many holy men, who did not spread themselves out with an empty show of leaves, but were bowed down by the weight of the true fruits of spiritual knowledge: of whom it is written in Acts: 'But when they saw the boldness of Peter and John, and perceived that they were ignorant and unlearned men, they were astonished' (Acts 4:13).
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.
