The Christian believes in the Trinity: that God is one, yet is three distinct persons—Father, Son, and Holy Spirit. Each person of the Trinity is independent, but never acts independently. Each is a distinct person, but those three persons are one in purpose, in essence, and in nature. The finite mind finds it difficult to comprehend this mystery; it must be accepted by faith: “And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him” (Hebrews 11:6, NIV).
The Apostles’ Creed, a statement of faith accepted by the church down through the ages, begins by mentioning all three persons of the Trinity: “I believe in God the Father Almighty, maker of heaven and earth; and in Jesus Christ His only Son our Lord; who was conceived by the Holy Ghost.”
The Westminster Confession carries an eloquent defense of the Trinity: “There are three persons in the Godhead, the Father, the Son and the Holy Ghost; and these three are one God, the same in substance, equal in power and glory.” (NOTE: The Confession has been reworded in modern language.)
The understanding that God is a Trinity is unique to Christianity. Most non- Christian religions are either animistic or polytheistic; the few that believe in one God have no understanding of His being three persons in one. All major pseudo-Christian cults emphatically reject the belief as well.
