It is hard to get a verse in the bible explaining the trinity because it is a human construct to define the relationship of the three persons of God.
Over the past six months we have looked at what each part of the trinity has done through the Christmas, Easter and Pentecost services.
The Gospel reading is a very concise explanation of how these three persons work together. The Spirit gives to us what it receives from Jesus and Jesus gives to the Holy Spirit what was given to him by God.
Seeing the Trinity in the first reading is hard. Who is the “I”? Is it Jesus or the Holy Spirit? Is wisdom meant to be the Holy Spirit? Which makes the person referred to as “I” Jesus. It is a risky act to find the trinity in the Hebrew Scriptures, because they were not talking of God in three persons.
The letter from Paul gives us the trinity as it relates to our lives. We have peace through Jesus and love through the Holy Spirit. This gives us hope through God.
Yet another tricky thought is that we talk of God in two ways. We talk of the Trinity being one God, but when we talk of the father, we commonly call that part of the Trinity God. So there is one God the Trinity and then there is God as the Father.
There are a number of problems for theologians in understanding the trinity. We can focus more on their oneness, minimalizing the uniqueness, or, vice versa, we focus on their uniqueness, minimalizing the oneness. There is also the issue of giving stronger emphasis on one part of the Trinity and scale down the other two.
To explain the trinity to children and the ordinary believer, the trinity has been compared to apples, a person, a shamrock, water or any other three part relationship.
For me it is God around us, God with us, God in us.
The fact is that it is about a relationship between the three persons, and how they work together to bring wholeness. Without a relationship their actions are mute. The ability for either to do what they do they need to be in relationship.
That goes for us too. If we want to do anything for God we must first be in relationship with God, and not just one part, but in the Holy Trinitarian relationship.
