It is common today for commentators to point out that the three major world faiths are very similar in that they all share a belief in one God: Allah for the Muslim, Yahweh for the Jew and 'Abba' God the Father for Christians. While it is true that Christians believe in one God, Christian faith departs radically from Islam and Judaism in its belief that in the one God there are three Persons: God the Father, God the Son and God the Holy Spirit. Furthermore — and this is an even more scandalous idea as far as the other two faiths are concerned - we believe that Jesus of Nazareth, the Second Person of the Trinity, God the Son, entered time and space and lived as one of us.

Belief in the Trinity is a central mystery of Christian faith. We are baptized 'in the name of the Father and of the Son and of the Holy Spirit' (Matt. 28:19), and we are invited to develop a relationship with each Person of the Blessed Trinity. Jesus' life, work, ministry, preaching and teaching all testify to this fundamental truth of Christian revelation.

In fact, the doctrine of the Most Holy Trinity could be described as the central mystery of the Christian faith and life, and it is this mystery that we are celebrating and rejoicing in today, Trinity Sunday.

For many Christians, the 'mystery' of the Trinity remains just that: a mystery. But the word in this sense is not used to mean a conundrum, puzzle or riddle that is impossible to solve, but a holy and sacred truth which we will only be able to penetrate more deeply if we ask the Holy Spirit to shed his light and truth into our minds and spirits. Instead of saying, 'I can't get my head around the Trinity', we need to say, 1 need God's help to get my head into the Trinity.' In other words, we need to pray, 'Lord, teach me, show me, guide me, lead me into the beauty, glory and majesty of the mystery of your Blessed Trinity.'

Try praying the following prayer today.

'0 my God, Trinity whom I adore, help me to forget myself entirely so as to establish myself in you, immovable and peaceful as if my soul were already in eternity’ (Blessed Elizabeth of the Trinity)
