The late patriarch and founder of the Catholic Apostolic Church of Antioch understood well the importance of the soul in the celebration of the sacraments and the mysteries of the church.  In his book The Sacramentarion, he wrote:

Let all the Archbishops, Bishops, Priests and Deacons and all in the Minor Orders realize the inherit Sanctity of the Soul in the offices they hold and fill.  Let them know that it is a sanctity begotten of realized spiritual grace and power.  Let there be illumination and not the outer sanctity resulting from a false and earthly atmosphere, which has come to surround all the offices we hold and claim. Let there be a new Integrity of Light! — Herman A. Spruit
