Jesus, Cornerstone of Our Faith

God has showered humanity with gifts and blessings, but humanity continues to abuse those gifts. We have been entrusted with a creation to care for, and in our shortsightedness we abuse and pollute the earth, even bringing about the extinction of entire species. We have been given the ability to create so many wonderful things, and even this gift we abuse as we gather and keep as much as we can for ourselves.

This is nothing new. Even in the days of Isaiah it was clear the people turned away from God’s gifts. God expected righteousness and justice. Instead the people responded with bloodshed and suffering, turning away from God.

Even if you can think of all the ways you have not turned from God and all the ways you have been faithful, it does no good. As Paul reminds us in the reading from Philippians, “Yet whatever gains I had, these I have come to regard as loss because of Christ” (Phil. 3:7). Even all of Paul’s good and faithful acts add up to nothing. For Paul, and for us, all that matters is Jesus.

As Christ himself reminds us, he is our rock, our cornerstone. Jesus is the foundation for our faith and the foundation for our lives. Even as we turn from Jesus, even as we reject Jesus, he returns to us with love and forgiveness. This is the grace of God, the love of God coming into our world and into our lives. To our joy we discover the open arms of Jesus on the cross, bringing life into this world even where there is death; bringing hope where there is despair; and bringing resurrection to all creation.

Gospel: Matthew 21:33-46

Jesus tells a parable to the religious leaders who are plotting his death, revealing that their plans will, ironically, bring about the fulfillment of scripture.
[Jesus said:] 33 “Listen to another parable. There was a landowner who planted a vineyard, put a fence around it, dug a winepress in it, and built a watchtower. Then he leased it to tenants and went away. 34 When the harvest time had come, he sent his slaves to the tenants to collect his produce. 35 But the tenants seized his slaves and beat one, killed another, and stoned another. 36 Again he sent other slaves, more than the first, and they treated them in the same way. 37 Then he sent his son to them, saying, ‘They will respect my son.’ 38 But when the tenants saw the son, they said to themselves, ‘This is the heir; come, let us kill him and get his inheritance.’ 39 So they seized him, threw him out of the vineyard, and killed him. 40 Now when the owner of the vineyard comes, what will he do to those tenants?” 41 They said to him, “He will put those wretches to a miserable death and lease the vineyard to other tenants who will give him the produce at the harvest time.”
  42 Jesus said to them, “Have you never read in the scriptures:
 ‘The stone that the builders rejected
  has become the cornerstone;
 this was the Lord’s doing,
  and it is amazing in our eyes’?
43 “Therefore I tell you, the kingdom of God will be taken away from you and given to a people that produces its fruits. 44 The one who falls on this stone will be broken to pieces, and it will crush anyone on whom it falls.”
  45 When the chief priests and the Pharisees heard his parables, they realized that he was speaking about them. 46 They wanted to arrest him, but they feared the crowds, because they regarded him as a prophet.
