If you ask people why they go to Mass, you are sure to get a lot of answers. “I go because I want to receive the Eucharist.” “I go to spend time with family.” Others will remark “I want to hear the Word of God.” Someone else will say “I like the preaching,” Ok, maybe I just hope someone would answer that. However, all these answers fall short: Catholic Mass is about perpetuating the Paschal mystery. Mass is a sacrifice, in which we all participate, led by the priest.
