The Trinity is a church dogma of the early church that attempted to express the fullness of God. It was seen as an active dance of the dynamic force of God. It was limited, not by God but by the early Christians' ability to understand the Cosmos and the world itself. It was a human doctrine limited by their circumstances and culture. It was tribal which reflected the tribal nature of the time. It is a doctrine that in its time was progressive as it broke the boundaries of tribalism and was inclusive of people from all races who embraced one God as understood through Father, Son and Holy Spirit.
We live in a new age with more knowledge. We know the Universe is huge. We know that God created the universe that is ever expanding. The suns in the universe are so numerous that if each sun was represented by a grain of sand were put into a hopper train car, the number of cars filled with sand would be and endless string of cars filled full of sand on track going 24 hours a day, seven days a week for more than 40 days. This would be for suns alone, the planets that go around each of the suns would magnify this amount many-fold. There is lots of life in the universe! On earth, we need to see that we are all connected through God to every living thing. We are all related. We must put away tribalism and respect each other, embrace each other as God is in all and all. We are one before God, all equal in God's eyes. Fear is something that we must, if we claim Christianity put aside. We are all God's people of the Planet Earth which we celebrate today.
