As we begin the great liturgy of the Paschal Mystery, we hear a lot of detailed instructions from our God. God commands the Israelites to celebrate the Passover meal in a very specific way. St. Paul teaches us what was handed on to him -- namely, how Jesus Christ celebrated the Last Supper and commanded us to "do this in memory" of him. In the Gospel, St. John relates what happened during that meal, when Jesus washed the feet of his disciples and said to them, "What I have done for you, you must do for one another." We would all do well to hearken to the words of the Blessed Virgin Mary, who spoke before Jesus' first miracle at the Wedding at Cana: "Do whatever he tells you."
