In Christianity, we belief that God the father Almighty is God. God the Son Jesus Christ is God and God the Holy Spirit is also God. However, there is one thing they all share in common and that is "GOD". The three persons are the same in all things. They are just different in terms of their relationship with one another. In other words, The father is God. The Son is God and the Holy Spirit is also God. However, the Father is not the Son. The Son is the Holy Spirit and the Holy Spirit is not the father. To sum it up, there are three distinct persons in One God. The LOVE between the Father and the Son is so great that the Holy Spirit proceeds out of such relationship. The Father shares all that He is with the Son and the Son with the Father in Such a way that the Father and the Son "are one". The love is so great that the Holy Spirit "spirates" or proceeds out of such relationship. Remember this happens outside space and time. There is no beginning and there is no end. It was there in the beginning it is now and ever shall be, world without end.
