Today's gospel reading recounts the first mission of the Church: the sending out of the seventy to the villages of Palestine (Luke 10:1-12, 17-20). We are the inheritors of that mission, into all the world.
Pope Benedict XVI Message for the World Mission Day 2006
"Charity: soul of the mission"
"Unless the mission is oriented by charity, that is, unless it springs from a profound act of divine love, it risks being reduced to mere philanthropic and social activity.
In fact, God's love for every person constitutes the heart of the experience and proclamation of the Gospel, and those who welcome it in turn become its witnesses. God's love, which gives life to the world, is the love that was given to us in Jesus, the Word of salvation, perfect icon of the Heavenly Father's mercy.
The saving message can be summed up well, therefore, in the words of John the Evangelist: "In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him" (I Jn 4: 9).
It was after his Resurrection that Jesus gave the Apostles the mandate to proclaim the news of this love, and the Apostles, inwardly transformed by the power of the Holy Spirit on the day of Pentecost, began to bear witness to the Lord who had died and was risen. Ever since, the Church has continued this same mission, which is an indispensable and ongoing commitment for all believers."
