If no priest showed up to ay Mass I would be very disappointed because I could not receive the Eucharist and come closer to God. What would we be doing? We would probably jut be sitting there looking at each other. If no priest showed up I wonder where they are, maybe t6hey are sick or the schedule mis mixed up, or they forgot.
Maybe there are not enough priests to cover mass all of the time. We need to pray for men so they will jear God calling them to become a priest. I have never really thought about a priest not showing up for Mass. I always just know they will be there.
