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 about the initial call of Abraham; it is used by the editors of the Book of Genesis as the launch of an extended saga of Abraham and his offspring. He is a semi-nomad who moves around with his large extended family from place to place; in this short account of his vocation, he is summoned by God to leave the past – his ancestors – behind and set off to a place that God will point out to him and will make his own. Responding to this, Abraham will not only be blest himself but will be a source of blessing to those who come across him – indeed to all people. But God is not understood quite the way we might envisage Him today, for he tells Abraham that He will curse those who curse him.

The first reading is chiefly the story of the temptation in the Garden of Eden often referred to as the Fall. It is a story that must have been told in various forms throughout the history of the descendants of Abraham. Other ancient cultures had similar stories, you may have heard of Pandora’s box , an ancient Greek story. These tales are about what it is to be human, about the pitfalls of human curiosity and about the cause of all the different evils in our world. They have all been told and retold time and again to different listeners and adapted appropriately, but all make much the same point. Our version in Genesis delightfully describes the human process of temptation; it starts, with what so often is the case, with a prohibition – “you mustn’t …” It proceeds with slightly changed interpretations of what is forbidden – “was it any of the trees in the garden?” and “You shall not eat nor even touch!” Then the victim of temptation just thinks the command is wrong and selfishly given – “the moment you eat it … you will be like gods!” We can all recognise this process and it should help us combat some of the temptations to selfishness that we have. Some Christians see this as an historical account and as the beginning of sin and death in our world which they call Original Sin. The story in Genesis goes on beyond what we hear today, with a glimmer of hope, saying:
