Quick recap:
1st Reading - More vineyard stories :)
Psalm 80 - The vineyard of the Lord is the house of Israel
Epistle - Phil 4 - motivational letter from Paul
Gospel -Matthew 21 - A landowner leased out his vineyard before leaving on a journey, and the tenants killed his servants and then his son when they came to collect the produce. In the first reading, we hear God's frustration. His chosen people have turned away, repeatedly. In the Gospel, Jesus highlights the continued behavior of the Jews, who ultimately kill the Son of God. This sets the backdrop for the psalm. In the psalm, we hear God's response to the Old Testament, and we add our plea that God protect this vineyard - us! This is nothing new to God - how many times had Israel sinned and repented? Not to mention us and our current society. Over and over, we beg God for mercy. We must have contrite hearts before God, and belief that our prayers will be heard.
