The Holy Trinity
God is one God in three different person, not three god but one God, coming from one being, God the father is the first person of the holy Trinity, the second person of the trinity is Jesus Christ the son, and the third person is the Holy Ghost. The father as no beginning or end, the son is generated from the father and the Holy ghost proceeds from the father and the son. God the father is called the creator, God the son is called the wisdom of God and the Holy Ghost is called the sanctifier. The dogma of the holy trinity is a mystery of the church that is probably the most left un-understood.
