Trinity Sunday B

Jeff Bagnall • 17 May 2024

Deuteronomy is a book aimed at reviving the enthusiasm of the Jewish people for their religion, and re-kindling their sense of community. Centuries before Deuteronomy was even written the Jewish people had been successfully led out of slavery in Egypt, and eventually entered the land they are in at the time of its writing and which they consider to be a gift to them from God. The author puts into the mouth of Moses a whole series of speeches addressed to the people before they cross the river Jordan to enter this land. In chapter 4, ( verses 32-40 omitting 35-38 ) what is said in the supposed context applies to the people at the time of its composition but also can be adapted to ourselves today: Look what God has done for you, do what God wants of you and all will be well! We still believe in God as a great creator, Who through His Spirit and through His Word makes us what we are, however we would not now think that we alone are God’s people or that He would give us the good things we have by doing awful things to others. Just as creation is an ongoing process so our understanding of God through creation changes and develops through time – we must never think we understand God!

In Paul’s letter to the Romans, (8:14-17) , he writes among other things of the role of the Spirit in our lives. The effect of the movement of the Spirit is what we read of last week on the feast of Pentecost. The whole of the letter is a well structured discourse about life in the Spirit brought through Christ. Each verse leading up to our reading is in the original connected – using 'for', 'therefore', 'indeed', 'but 'or 'however '– and literally our reading starts “Who indeed by the Spirit of God are being led, these are sons of God.” As the Son takes on our humanity, so we, by the influence of the Spirit, share in this kinship, forming a community both of suffering and of glory. Paul’s ideas are a radical development from the much narrower view of God’s activity that he would have had as a Jew. It is he who wrote earlier to the Galatians (3:28) “There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for you are all one in Christ Jesus”. What would he write today about non-believers, adherents of other faiths and different Christian denominations? The mystery of the Trinity is surely partly about community in oneness.

The Gospel from Matthew (28:16-20) is the last paragraph of his gospel. He has found a good way to conclude his work. The disciples see Jesus in Galilee; something that has been planned before when the women at the tomb are told the disciples will see Jesus in Galilee. They recognise Him, but with some hesitancy. What they must do, not just in Galilee but for all nations, is bring people into the community that they have; they will use the Baptismal formula that was in use in Matthew’s own church community; it names together the Trinitarian nature of God, which throughout the Gospel has been seen under the different roles, of Father, Son and Spirit; people will be incorporated in some way into the community of God. It wasn’t really until 400 years later that some understanding of Trinity was officially formulated, but even to this day it is a mystery in which we are involved.

Jeff's jottings: Three in One

The first reading comes from a section of Isaiah which nowadays we associate with Christmas. In Advent (the 4th Sunday of Advent, cycle A) we heard a prophecy of the birth of a young lady’s first child to be called Immanuel (‘God with us’). There are two other children in this section of the book; they have equally meaningful names: Maher Shalal Hash Baz (‘disaster will come upon many’) and She’ar Yashub (‘rescue for some’). All this precedes the section we read today; and after our reading comes the source of the well-known Christmas carol, “Unto us a son is born” (Isaiah 9:6). Our reading refers to Zebulun and Naphtali, which were tribal areas in the break-away northern kingdom. It is in these areas, we read, there have been difficulties but also glorious times (perhaps in the future). Because of the editing of the book of Isaiah over many centuries, it is uncertain what the historical reference is; it could be about 733 BC when the Assyrians invaded that land, but would eventually loose power, or it could be about the 6th century BC exile in Babylon and the eventual return. But for us today, it is clearly linked with the words of the gospel: there may have been darkness but now the light begins to shine!

The Lord speaks to one of His spokesmen (such is a prophet), with a quite progressive message for the chosen people (for us); it announces that though they are chosen yet His purpose is to extend salvation to all peoples everywhere. This first reading is the second prophecy/poem about the Servant of the Lord, found in the part of the book of Isaiah put together during the Exile in Babylon. We have just a few of its verses read to us, but selected to make a very significant point: that the chosen servant is to be a light of the nations, so that salvation may reach to everyone – to the ends of the earth. We see this insight that struggled to develop throughout the history of the Jews before Christ, and still had difficulty being grasped in the early church – and perhaps in our church today. The universal love of God is now generally recognised in the teaching of various Christian denominations; but the practice of this love and of its implications is still a difficulty both for some sections of the church and for us individually. Imagine the situation of the Jews in Exile, hit by this message that God actually loves those enemies of theirs, and that they, being a light to the Gentiles, should show this love to them.
