Imagine you are Jesus at the Last Supper. You are about to die. What will keep your followers together when you are gone? What will keep your words alive among them? What will keep their hearts on fire?
The Mass. The celebration of the Eucharist. That is what Jesus relied upon. The church calls Eucharist "the source and summit of Christian life." At the Last Supper, Jesus took a loaf of bread, gave thanks, and gave it to His disciples saying, "This is my body, which is given for you. Do this in remembrance of me."
This is a sacramental remembrance: a remembrance that makes present what we remember.
In the Mass, Jesus is present and acting. That is where we encounter Him - not alone, but in company with others: in a communal meal where we listen to His words together, respond to them together, and experience His presence among us and within us.
All we have to do is pay attention at Mass, understand what we are paying attention to, and enter into it.
Take action: Next time you go to Mass, arrive a few moments earlier than usual so that you can prepare to enter more fully into the celebration. Take a few quiet moments to recall that Jesus is present and active in the Mass. How does this make you feel? How do your feelings impact your desire to participate more fully in the activity of the Mass? What choice will you make to enter more fully into the Mass?
