Trinity Sunday B

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 five books of the Bible are called the Pentateuch, which comes from the Greek words for five and for scroll; together these books are called the Law, particularly in the Jewish religion. The last of these five books is called Deuteronomy, which comes from the Greek words for second and for law, because this book is like a summing up of the laws and experiences of the previous books of the Law. It is chiefly a story of the relationship between God and the people; he saves and looks after them time and again in wonderful ways, they repeatedly complain and let Him down – it’s the story of our lives too, perhaps. The verses we have today focus on the manna, which they received as a gift from God when they found themselves in the desert with no knowledge of how to survive there and hence made a complaint against God for leading them there through Moses. Manna was seen as miraculous food that was the gift of life for them from God even though they were not deserving. From this it is clear how this is related to the sacrament of Communion.

Exodus is the second book of the Bible; it is based on and around the story of slaves escaping from their oppression in Egypt and travelling through the hostile desert under the leadership of Moses; and it was in this process that a relationship was built up between them and the one God who would be theirs from then on forever; it was the God with the mysterious name of Yahweh, meaning something like ‘I am who is.’ This basic oral account over time gained a great number of elaborations and additions before it settled into the written form in the Bible that has now been more or less unaltered for about two and a half thousand years. In our extract for today’s first reading we hear of this aloof and even fearful God condescending to meet with Moses the people’s leader on the heights of the sacred Mount Sinai. This God then announces himself (always referred to in this personal way) as kind and forgiving, despite the unfaithfulness of the people whose God He is. Moses is encouraged by this revelation and feels enabled to respond on behalf of the people he leads, with worship and prayer for blessing and forgiveness. It is this threefold pattern in this section of the Exodus story that is seen by Christians to suit this day’s Feast of the Trinity – the threefold pattern of God the aloof, the one who shows Himself and the one who enables an appropriate response.
