The Most Holy Trinity - Year C

Jeff Bagnall • 3 June 2025

The first reading is from the book of Proverbs ( 8:22-31), which is classed as wisdom literature. The section we have for today is a poem spoken by wisdom herself, Sophia in the Greek. The whole passage is chiefly about the presence of wisdom while God was creating. Among the nations surrounding the chosen people there were other collections of what may be called wisdom writing. Here she is an aspect of God before, during and even after the process of creation. In Christian circles this developed and Wisdom came to be identified eventually as one of the three that comprise God – the doctrine of the Trinity; but this took time and is still a mystery. Despite all this theology and doctrine we see in it, the reading is a quite delightful poem.

The second reading is from Paul’s letter to the Romans ( 5:1-5), the most structured of all his writings. He had had difficulties of various kinds in his life as a Christian, and here he tries to express what he has learnt from this. It is a suitable reading for Trinity Sunday because he explains something of the relationship of God to us Christians. It is through the presence of God in Christ with us in our humanity that we who are enabled to believe, realise our right relationship with God (which is what the word ‘justification’ means in Paul). He wants to ‘boast’ of this, but maybe being proud would be a more appropriate way of saying it. When a believer has hardship one is strengthened and builds up a great hope – if for nothing else, for a share in the glory of God; and this strength is the very Spirit of God within us bringing us a deep peace through it all. Thus our life is involved in the very threeness of God, through Christ and the Spirit.

The third reading is from John’s gospel ( 16:12-15) which is clear from its style. The words attributed to Jesus express both the unity of Father, Son and Spirit, and also the promise that the understanding of the significance of this threeness will develop through time. It can develop for us as individuals in different ways or areas of our lives; for some it might be in an intellectual way with the use of words and thoughts, but for others in a devotional way as they grow loving Jesus or experiencing His Spirit, and for some it might work out in their practical living like Jesus, living for others and with the energy of God’s Spirit. For the Church as a whole it developed the Creed with its faith in the Trinity, but this doctrine, will always be a mystery, although what is important is not so much any grasp of the meaning, as living out the practical implications of being spirited.

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.

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.
