in the Divine Liturgy and the Eucharist we listen to the word of God, we then view the One-time sacrifice of the Lord, and then we experience the totality of God’s grace through the eating of His body, then in prayer we experience the soul satisfying relationship with God.
So the mind-body-soul relationship is in the fullness of orthodoxy
Real Christianity as seen in orthodoxy, in the One Holy Catholic church (as well as our sister Eastern Orthodox, Oriental and Assyrian church), is not a religion, but a relationship with God, based on putting one’s faith in Christ's death on Calvary and His resurrection from the dead, His glorification and commemorating what He taught.
Orthodox doctrine comes from Scripture, not Popes or councils. The Roman Catholic Church is an institution created by man for man. That the Pope is styled “Vicar of Christ” is evidence. He and the organization he leads is a substitute for the preaching of the Gospel, and a poor one at that. Lots of ritual and color in RC ceremonies that appeal to the pride of man and to his flesh.
