this the message , the unifying vision , that which the friar has dreamed ... seeing himself in personal combat with the devil , sighting himself as a high priestbeing transubstantiated into the son made present through his consecrated hands ... celebrating the holy mass but in like manner celebrating as he tortures , as he pierces and presses , twists and hacks , savages his way through that which is the blockage , the barrier , the refuge of the devil , namely , the body itself .
