Abba Theonas continues to draw Cassian and Germanus into the greater vision of the Christian life - guided not by law but by grace. The measure of holiness for the Christian is always Christ, the sinless one, and so even though our conscience does not rebuke us we know that we are but worthless servants who have only done our duty. We seek the purity of heart and chastity that not only avoids fornication but seeks freedom from all wantonness. In this the fundamental attitude of the Christian must be humility. We must live in a constant state of repentance, penance and prayer; understanding that daily we fall through weakness into the capital sins and that it is only by being lifted up by God's grace and participating in the perfect purity of Christ that we come to share in the holiness of God.
