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.

The first reading is a very upbeat announcement of the good times that the Lord will bring about for all nations. This is not just about the freedom of the Jews who have been in captivity, but it is a universal message of good times, with plenty of all the fruits of the earth and no fear of troubles. The destruction of death might be seen by Christians as the announcement of life after death, but when this message was first delivered, probably in the 6 th century BC, it meant no more will enemies kill each other. All these wonderful gifts from God are, however, delivered to all peoples “on this mountain,” a phrase that initially refers to the city of Jerusalem which is centred upon and around a prominent hill in the countryside; though the phrase was used symbolically to refer to all the people of Israel. So we see in this passage the basis for a future view of what God will do for all people on earth, but with the restriction of it being centred on the people of Israel; it is the vision of a prophet who sees the future darkly, reading it from the worldly state of affairs that he interprets from the standpoint of his assured belief that his is also the god of those who share his faith. We know ourselves that many of us Christians are caught in similar limitations in our vision of God’s relationship with the whole world and its people.

In the first reading we have a very good illustration of a successful approach to delivering bad news when you are a prophet and that is your job. The book of Isaiah has been heavily edited, and our reading from chapter 5 is very likely the first public appearance of the prophet. If you want the crowd to listen to you, you don’t want to be known as a prophet of doom. So Isaiah draws a crowd by saying he is going to sing a song, like a street busker setting up his spot. It’s a song, he says, about his friend; it’s told as though it is about a man setting up a new vineyard, but it is really about unrequited love. He did everything one should for the vineyard to be successful, but it just produced (literally) stinking grapes. The friend then questions the crowd: “is there anything more I could have done?” And he tells them he is going to completely wreck the area and make it a wasteland. Then, when the crowd has grown and is listening intently, like a punch-line the prophet announces: “this song is about the Lord and you Israel!” The image of the vineyard became quite popular in the sayings of prophets and even among the people themselves; one of their hymns is the psalm that follows the reading for today.
