"When you see the ordained priest at the altar raising the sacred host toward heaven, do not believe that this man is the true (principal) priest, but, raising your thoughts above what strikes the senses, consider the hand of Jesus Christ invisibly extended." -St. John Chrysostom
The priest whom we see with our eyes of flesh cannot penetrate all the depths of this mystery, but above him there is the intellect and will of Christ, the principal Priest. If the minister is not always what he should be, the principal Priest is infinitely holy; if the minister, even though very good, may be slightly distracted or occupied with the exterior ceremonies of the sacrifice, without penetrating their inmost meaning, there is above him One who is not distracted and who offers to God with full knowledge reparatory adoration of infinite value, supplication and thanksgiving of limitless power.
