According to the old Testament (original) Christian religion, God is one in his appearance. He is the beginning of everything and the Creator of all living beings. This perception of God was a dogma – the only true and unbreakable position affirmed by the Church. But in 4-5 centuries in Christianity there was a new dogma-Trinity. Its drafters represented God as three hypostases of one essence:

God The Father;
God The Son;
God Is The Holy Spirit.
All entities (Persons) are equal and come from one another. The new addition was actively rejected by representatives of Eastern denominations. In the 7th century, the Western Christian Church officially adopted the filioque Supplement of the Trinity. This was the impetus for the split of the United Church.

Man in the view of religion-the creation of God, and he is not given to know the essence of his Creator. Questions and doubts are taboo for a true Christian believer. Everything that a person should and can know about God is stated in the Bible – the main book of Christians. It is a kind of encyclopedia containing information about the formation of religion, descriptions of historical events before the appearance of Jesus and the key moments of his life.
