I admit I was mistaken in saying that priests could only be very evil or saints. A priest can attain many different levels of goodness. I see now that a priest can also be lukewarm, sinning often, but then confessing. My main point was that because the priest says Mass often, and saying Mass while in mortal sin is one of the greatest sins because it is torturing Our Lord, once a priest falls into sin he will become more and more evil every time he says Mass until he is completely evil. Thank you for correcting me.
