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 part of a heart-warming poem. It was written about the time that the people were going to be released from captivity by a friendly emperor, Cyrus. It attributes this release to the love of God, who has a special relationship of love for people, a relationship traditionally called a covenant. It is a two-way agreement: God will look after the people, and the people will live in a way pleasing to God. But the agreement is not conditional; it is not like God saying ‘if you keep my commandments I will be your protector and god;’ it is unconditional on God’s side: ‘I will be your God, so you will be my people however you respond to me.’ In the part of the poem we read today, the prophet is announcing to the people, God’s call to them; it is a call to give up any wickedness and turn their lives towards Him. But the prophet is also emphasising that God’s ways are mysterious, for He does not depend on the people behaving well for Him to love them and to be their God; there is no way they can deserve or merit God’s love, it is generous, free and everlasting. The extract is chosen for this contrast between God’s ways and ours, an idea taken up in the Gospel reading for today.

Reading Ezekiel we must remember that the Jews believed that they were the chosen people of the one and only God, Yahweh; they had laws and rules to live by and a covenant which they often thought of as ‘if we keep your laws, God, you will see that we prosper.’ Yet this arrangement didn’t seem to be working out in their history, especially when they were being taken over by a neighbouring empire. So much so that they began to think that they were being punished by God or even would die because of the sins of their ancestors; indeed they attributed all the difficulties and hardships of life to the original disobedience of the first humans ( Genesis 3 ), and they had a saying: “The parents have eaten sour grapes, and the children’s teeth are set on edge.” Ezekiel was trying to replace this idea with the fairness and mercy of God. Not only was God punishing the wrongdoer for his own sins and blessing the good, but saying that there would be forgiveness and blessing if the sinner repented and turned away from sin.
