The Apostles’ Doctrine believes in the only one GOD the Creator of Heaven & Earth and all Mankind. It is manifested to mankind as FATHER (Creator), SON (Saviour), and HOLY SPIRIT (in dwelling spirit) – Rom.8:11.
The Bible is the inspired Word of God, giving a true history of creation in the past to the prophecy of the ages to come regarding Heaven, Earth, and the destiny of humanity for future. We believe there is no salvation outside the Bible – the Word of God (The Saviour).
God is a Spirit , the Eternal One, the Creator of all things; and, of course, of all men, thus making Him their Father through creation. John 4:24 HE is the FIRST and the LAST and beside Him there is no God. Isaiah 44:6 There was no god formed before Him, neither shall there be after Him. Isaiah 43:10
Jesus is the SON of God according to the flesh (Rom 1:3), The very God Himself according to the Spirit (Matt. 1:23). Jesus is the Christ (Matt. 16:16), The Creator of all things (Col. 1:16,17); God with us (Matt. 1:23); God made flesh (John 1:1-14); God manifested in the flesh (1 Tim. 3:16); He which was, which is and which is to come, THE ALMIGHTY (Rev. 1:8; Isa. 9:6). To this, Jesus Himself testified when He said: "He that hath seen me hath seen the father" (John 14:7-11); and "I and my Father are one" (John 10:30). Since it took shedding of blood for the remission of sins of the world (Heb 9:22), God as the Father, being a SPIRIT, had no blood to shed; so He prepared a body of flesh and blood (Heb. 10:5), that He might fulfill the prophecy of Isa. 43:11; "Beside ME there is no SAVIOR"; and caused the angels to sing, "For there is born this day in the city of David, a SAVIOUR, which is CHRIST, THE LORD" (Luke 2) THE HOLY SPIRIT.
The Holy Spirit is not the third person in the Godhead, but rather the manifestation of the Spirit of God (the Creator), and of the resurrected Christ, coming to dwell in the hearts and lives of all men who will be obedient to the gospel, as the Comforter, Sustainer, and Keeper (John 14:16-26; Rom. 8:11). So there are not three GODS, but three MANIFESTATIONS of the ONE God.
