By Fr. Nnamdi Moneme, OMV, Catholic Exchange - The Eucharist demands change from us constantly because it is no ordinary or earthly food. When we eat earthly food, we receive strength to do what we want to do. But when we receive heavenly food, the food that God gives to us and food that we know about only because God chooses to reveal it to us, God strengthens us do what He wants us to do.
