We believe in one (composite) God. The word in Hebrew used for one is the word 'echad.' That verse is Deuteronomy 6-4 which states, “The Lord our God, the Lord is one.” When using the word ‘echad’ it allows the one to be composite. If the writer had wanted the one to be singular he would have used the word 'yaclid' which means singular one. An example would be a pair of shoes. There are two shoes. The word ‘echad’ would be used. If there were one shoe the word ‘yaclid’ would have been used. Our composite God has three distinct persons.
They have a hierarchy in that God the Father is first, God the Son is second and the Holy Spirit is third. We believe in the Father, the Almighty, Maker of heaven and earth of all that is seen and unseen.
In the first chapter of the Book of Colossians the Apostle Paul writes, ”He (Jesus) is the image of the invisible God the first born overall creation. For by him all things were created: things in heaven and on earth, visible, whether thrones or powers or rulers or authorities: all things were created for him and by him.” We believe in Jesus Christ who is the only begotten Son of the Father. Before I go to my next statement I would like to discuss the word firstborn in the next statement. The words firstborn can have several meanings from the original Greek text, of which the New Testament was written. There are two separate words in Greek for the English word firstborn. If a child was born as what we would consider normal childbirth the Greek word 'protokisis' is used. Another Greek word used for translation into English as firstborn is the Greek word 'protokos.' This means begotten and has nothing to do with childbirth. You can see the extreme difference in these two Greek words. In the Old Testament the firstborn had the dignity and superiority over other siblings. The firstborn had a favored hierarchy of inheritance. The word used in Colossians is the Greek word protokos.
We believe in the Holy Spirit the third person of the Trinity. After Christ ascended into heaven the Holy Spirit came to be our comforter.
