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.

The first reading repeats the introduction from last week so as to make sense, for there follows a continuation of the previous words spoken to the crowd by Peter. The people have been moved by the accusation of putting Jesus to death, and they want to know what they can do. Peter calls upon them to be baptised. As John the Baptist seems to have preached to his listeners, Peter begins with the need for repentance and the need for baptism. You could feel sorry for the past but this repentance means ‘change your attitude to life.’ Baptism is a washing symbolic of starting with a clean sheet; here it is for starting a new life caught up in the life of the risen Christ. In his life our past is transformed; those baptised will have the forgiveness of past sins. The words translated ‘forgiveness of’ could equally well be translated as ‘release from,’ meaning a freedom from the debilitating affects of past sins. Those baptised will share in the Spirit of Christ, the Holy Spirit of God. God wants people of all kinds to come into this communion with Him.

In Luke’s Acts of the Apostles, today’s first reading is the first sermon from Peter after the resurrection. The literary style is not that of a Galilean Jew, but the content is believable as a very early expression of the initial preaching about Jesus. In this first century account of the beginnings of Christianity, Peter is a key figure in the growth of the early church, together with Paul, the missionary to the Gentiles. It is significant that it is a Jewish audience in Jerusalem that Peter is addressing. Jesus is referred to as the Nazarean and there is uncertainty whether this means a man from Nazareth or one specially dedicated to God, as for example, Samson in the Old Testament, called a Nazirite. The understanding of Christian beliefs develops over time, so Peter speaks about God working through Jesus where we might be clear that Jesus is Himself God; but he does see Jesus as the fulfilment of the hopes of the Old Testament and quotes Psalm 16 verses 8 to 11, which was a song originally about someone faithful to the Lord, maybe king David, being looked after by Him; (it is used for the responsorial psalm this day). In the sermon Peter accuses the Jews of engineering the death of Jesus in an anti-Semitic way; this attitude was decried by the Church most noticeably in the 20th century in the Second Vatican Council initiated by Pope Saint John XXIII, with the words: “Furthermore, in her rejection of every persecution against any person, the Church, mindful of the patrimony she shares with the Jews and moved not by political reasons but by the Gospel’s spiritual love, decries hatred, persecutions, displays of anti-Semitism, directed against Jews at any time and by anyone.” (The Church and non-Christian religions, Nostra Aetate, Oct. 1962). But for us the positive message from Peter’s sermon is that the Spirit of God is now poured out into creation because of the resurrection of Jesus destroying the deadliness of death and the power of evil in our lives. The second reading is part of an address to early Christians, probably Gentile converts. It is about what it means to be a Christian, noting that it is brought about by Christ – the writer uses the word ‘ransomed’, but no words can really capture the mystery of it. The mystery is that the final age has been initiated thanks to the work of God in Christ, through His life and death. The imagery of the sacrificial lamb which is used is derived from the bloody sacrifices of the Jewish Temple which at the time of this letter had been destroyed. And those addressed are living like people in exile and are urged to conduct themselves reverently in this situation; this reflects how the Jews were when they were in exile in Babylon, they had to work at it to keep themselves true to their calling. So, though we are elevated in our being through the work of God in Christ, we are for the time being in this world and must live here in a way becoming of our status.
