The 1st reading shows how Elisha, as the man of God, fully aware of what God can do, insists that twenty barley loaves are enough for a large group of 100.
This reading points toward the Gospel reading, when Jesus fed 5000 men, and others, with 5 loaves of bread. It is one of several signs in teh Gospel according to St. John, and points to how God provides life-giving gifts for His people, which Jesus will explain in detail in the coming weeks in the rest of chapter 6.
Yet the people see Jesus's extraordinary ability and think He should be a king.
Instead, they, and we, are called to see in these signs that God provides for our greatest need, that of salvation, in Christ. We turn to Him. He binds us together in one faith in our God Who saves us fully, and sustains us with His life through the sacraments, as part of one church that is sent to serve the world. As one major take-away from the National Eucharistic Congress, God gives us His life so that we can bring life to the world, that all may see this God at work to fill us abundantly.
On this day when we celebrate our Grandparents and our Elders, we give thanks for how faith is handed on from one generation to the next, and we can draw upon those ageless and timeless principles to sustain us in the life that God has given to the world through His Son Who continues to offer Himself to us in the Eucharist.
