Christians believe in God the Trinity — Father, Son and Holy Spirit. The Trinity is not three gods, but one God in three Hypostases, in three personal beings. What mathematics and logic consider an absurdity constitutes the cornerstone of our faith, namely that 1=3 and 3=1. Christians participate in the trinitarian Godhead not through logic but through repentance, that is, through a complete change and renewal of the mind, heart and feelings (the Greek word for ‘repentance’ — metanoia — literally means ‘change of mind’). To touch upon the mystery of the Holy Trinity is impossible unless the mind changes from a rational way of thinking and becomes illumined by divine grace.

The doctrine of the Trinity is not an invention of theologians, not a teaching which gradually developed within the Church, but divinely revealed truth. At the Baptism of Jesus Christ, God reveals Himself in all clarity to the world as Unity in three Persons: ‘Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heaven was opened, and the Holy Spirit descended upon him in bodily form, as a dove, and a voice came from heaven: Thou art my beloved Son; with thee I am well pleased’ (Luke 3:21-22). The voice of the Father is heard from the heavens, the Son stands in the waters of the Jordan, and the Spirit descends upon Him.
Jesus Christ repeatedly speaks of His unity with the Father, and of His being sent into the world by the Father. He also promises to send His disciples the Spirit, the Comforter, Who proceeds from the Father (John 14:16-17; 15:26). Sending His disciples out into the world to preach, He says to them: ‘Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit’ (Matt.28:19), which becomes the baptismal formula of the early Christian Church. The apostles themselves refer to the three Persons: ‘There are three witnesses in the heavens; Father, Son and Holy Spirit, and these three agree’ (1 John 5:7).
At the Incarnation of the Word God revealed Himself to the world as One in three Persons. The Jews, who had preserved their sacred faith in the one God, would have been unable to grasp the idea of a Divine Trinity as this would unmistakably have been taken to mean polytheism. At a time when polytheistic religion ruled the world, the mystery of the Trinity was hidden from human gaze. It was hidden as if it were in the very depths, in the very heart of the dogma of the divine unity.
HOW TO EXPLAIN THE MYSTERY OF THE HOLY TRINITY?
One of the simplest ways of explaining the mystery of the Trinity is that reportedly given by St Spyridon of Trimithund at the Council of Nicaea (AD 325). According to tradition, when asked how it is that Three can simultaneously be One, St Spyridon responded by taking up a brick and squeezing it. From the soft clay in his hands a flame showed up while simultaneously water flowed downwards. ‘As there is fire and water in this brick’, said St Spyridon, ‘in the same way there are three Persons in the one Godhead’.
Another version of the same story (or it may be a different story) is found in the Acts of the Council of Nicaea. One philosopher argued long and hard with the Fathers of the Council, trying to prove logically that the Son cannot be consubstantial with the Father. Exhausted by long debates and eager to leave, the Fathers were suddenly confronted by a simple elderly shepherd (identified as St Spyridon), who announced that he was prepared to argue with the philosopher and disprove his arguments. Turning to the philosopher, the shepherd looked at him severely, and said: ‘Listen, O philosopher, God is one, the Creator of heaven and earth, Who has created all things through the power of the Son and the operation of the Holy Spirit. This Son of God became incarnate, lived among people, died for us and rose again. Do not labour in vain to seek evidence for that which is comprehended by faith alone, but answer me: do you believe in the Son of God?’ Struck by these words, the philosopher could only say, ‘I do’. The shepherd said: ‘If you believe, then let us go to the church and there I will bring you into communion with this true faith’. The philosopher immediately stood up and went with the shepherd. On his way out, he said to those present: ‘When people tried to convince me with words, I countered words with words; but when a divine power came forth from the mouth of this old man, then words were no match for this power, as man cannot contend against God’.
We have already faced a very similar dilemma when discussing the doctrine of God: human words cannot convey the divine reality. God’s enlightenment and His grace are needed, for us to comprehend trinitarian theology. No terminology or formulation is adequate to communicate the mystery of the Trinity. Yet the Christian faith is above all trinitarian, and it is crucially important for every Christian to partake fully in this mystery. For an Orthodox Christian, the Trinity is not an abstract theological concept: it is a reality which is to be lived through. The Trinity is Someone to Whom we pray, but it is also Community, the Communion of three in one, the Family in Whose image we build up our own human community
