In this week’s Gospel, Jesus tells us that the greatest commandment is to love God “with all your heart, with all your soul, and with all your mind.” Then the second greatest is to “love your neighbor as yourself” (see Mt 22:34-40). One of the insights of John Paul II’s Theology of the Body is that this call to love is revealed in our bodies. “This is the body,” says John Paul II, “a witness … to love” (TOB 14:4). It’s a witness to the love God has for us, the love we are to have for God, and the love we are to have for others. How so? It’s the body that reveals the call to become “one flesh.” The holy communion of man and woman is a “great mystery” that reveals how God loves us in the holy communion of the Eucharist (see Eph 5:31-32). God wants to marry us, become “one” with us in the flesh. “This is my body given for you…” says Jesus to his Bride in the Mass. In receiving Christ’s body in so intimate a way, we have all we need when Mass is ended to “go in peace to love and serve the Lord and one another.” We have God’s body in our body, the source of all love. Astounding.
