Cassian begins with a rather dense discussion of the nature of the desires of the flesh and the spirit. While rather challenging to follow, the payoff in regards to clarity is great. The struggles between the flesh and the spirit create a kind of equilibrium for the will that prevent us from falling into excess. The desires of the flesh are limited by spiritual fervor and the ascetic disciplines and the desires of the spirit are balanced by the limits of human nature. We are prevented from simply doing "what we want to do" and the internal struggle that is an ever present reality leads us to discretion and obedience. Discussion ensued about how we often seek to anesthetize ourselves to this struggle and inner dis-ease and characterize it as frustrating or something to be limited. Rather it has been given to us by God as something which is beneficial and keeps us on the path of humble self discipline and reliance on the grace of God.
Conferences of St. John Cassian: Conference Three on Renunciation -Part V and Conference Four on Desires of Flesh and Spirit
We continued to discuss the final portions of Conference Three where Cassian seeks to capture the relationship between grace and free will. Synergy best expresses this relationship: God does not force His grace upon us but guides and strengthens us when we submit to his will. We cooperate. God works with us. We work with Him. God wants free-will partners. He created us to be His sons and daughters not His blind slaves. Once we come to know Him, however, we do become His servants, but we do it willingly, out of love. God offers us the gift of eternal life, but it is up to us either to accept or reject it. When God's hand of grace is grasped by our hand of faith, the result is salvation, wholeness, union with God. God has chosen to work through us, the members of His body.
Cassian moves on to discuss this in relation to the struggle between Flesh and Spirit in Conference Four.
