The Holy Mass and the Devil

Each Mass is the same sacrifice as that which Jesus Christ offered to His heavenly Father on Mount Calvary for the overthrow of Satan's power over mankind.  Hence, each Mass shakes the foundations of the devil's empire in this world; it causes him to tremble and take flight, giving him unspeakably great pain. - Fr. Michael Muller, C.SS.R.
