Deut. 4: 32-34, 39-40 / Ps. 33: 4-6, 9, 18-20, 22 / Rom. 8: 14-17 / Mt. 28: 16-20
Last Sunday we celebrated the sending of the Spirit, who sealed God’s new covenant and made a new creation.
In this new creation, we live in the family of God, who has revealed himself as a Trinity of love. We share his divine nature through his body and blood (see 2 Peter 1: 4).
This is the meaning of the three feasts that crown the Easter season: Pentecost, Trinity Sunday and Corpus Christi.
These feasts should be intimate reminders of how deeply God loves us, how he chose us, from before the foundation of the world, to be his children (see Ephesians 1: 4-5).
Today’s readings illuminate how all of God’s words and works were intended to prepare for the revelation of the Trinity and the blessing of God in Jesus Christ – the blessing we inherited from baptism and which we renew in each Eucharist. .
By the word of God, the heavens and the earth were filled with his goodness, we sing in today’s Psalm. Out of love, God called Abraham and chose his descendants to be his own people, says Moses in today’s first reading (see Deuteronomy 4:20, 37). Through the Israelites he revealed to the nations that he alone is Lord and that there is no other.
In Jesus, the word of God took flesh as the son of Abraham (see Matthew 1: 1). And Jesus reveals today in the Gospel that the only God is Father, Son and Spirit, and that he wishes to make all peoples his own.
As he led Israel out of Egypt, God freed us from slavery, Paul says in today’s epistle. When he adopted Israel (see Romans 9: 4), he gives us the Spirit by which we can know him as “our Father”.
As heirs of God, today we receive commissions from Moses and Jesus. We are to set our hearts on him and observe all that he has commanded. The Eucharist is his pledge – that he will be with us until the end, that he will deliver us from death to live forever in the promised land of his kingdom.
