...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'.
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 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 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 CassianMen seized of the urge to have a knowledge of God and to be pure in mind devote all their gathered energies to this one task. While they still live in the corruption of the flesh they give themselves to that service in which they will persevere when the corruption has been laid aside. And already they come in sight of what the Lord and Savior held out when He said, 'Blessed are the clean of heart, for they will see God' (Mt. 5:8).
John CassianIt is not our free will but 'it is the Lord who sets the captive free' (Ps. 145:7). It is not our own virtue but 'it is the Lord who lifts up those who were laid low' (Ps. 145:8). It is not application to reading but 'it is the Lord who gives light to the blind' (Ps. 145:8). It is not our cautiousness but 'it is the Lord who protects the stranger' (Ps. 145:9). It is not our endurance but 'it is the Lord who raises or gives support to the fallen' (Ps. 144:14).
