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.

From the last verse of the first reading (Isaiah 35:1-6a,10) it seems clear that this passage is referring to the return from exile in Babylon. We have to realise the symbolic significance of the desert; we still use the word today in our language and culture for a situation or a time of apparent hopelessness – when our world seems ‘barren’ (a similar word to desert). In the history of the Jews it begins with their escape from Egypt and their difficulties for a whole generation (as the story implies) of wandering in the desert – where God through Moses has led them. The period of exile in Babylon was a similar set-back for them as a nation but with a feeling of abandonment by God. So when the return to their own land is described it is envisioned as the blossoming of the desert. After the centuries of the editing of this book of Isaiah, we can only assume that our passage originated as a word of hope (perhaps when Cyrus of Persia conquered Babylon, with his policy of repatriation). The figurative blossoming of the desert is followed with the hope of miraculous cure for disadvantaged individuals. But then, as now for us, it is a poem of the wonderful and good things that God does and will do – an appropriate reading in preparation for celebrating the birth of Christ and all that means for us.

Back in the 8 th century BC this first reading is for Isaiah a vision and a hope based on his understanding of God and His relationship with this world. It is expressed by the prophet as best as he can as being like a dream for an ideal king, a descendant of David (son of Jesse), with wonderful gifts of spirit, like wisdom, empathy, understanding and respect for God. But also a dream of an unimaginable peace, even in nature and between humans and animals – in our eyes an impossible world. In addition, again “on that day” it is written, this peace will extend even to the Gentiles – more easily imaginable to most of us here and now, within our understanding of God’s universal love.
