Since the trinity doctrine claims Jesus is also the one God, an Adventist author from the 1800's wrote, “To believe that doctrine, when reading the scripture we must believe that God sent Himself into the world, died to reconcile the world to Himself, raised Himself from the dead, ascended to Himself in heaven, pleads before Himself in heaven to reconcile the world to Himself, and is the only mediator between man and Himself… We must believe also that in the garden God prayed to Himself, if it were possible, to let the cup pass from Himself, and a thousand other such absurdities.” — (J. Loughborough)
Some of those other absurdities it teaches is that Jesus is the immortal God but died, is the invisible God but was seen, is the omnipotent God but was strengthened by an angel, is the omniscient God but did not know the day of his return, is as great as His Father but His Father is greater than He, is equal with the Father and yet He is the Father, is the Son but the same age as the Father, is the Son who has a Father and the God who has no Father, is the begotten Son and the unbegotten God, is very God and very man, came out from Himself, prayed to Himself, gave power to Himself, thanked Himself, bore witness of Himself, went back to Himself, sits at the right hand of Himself, is His own Father and His own Son, left Heaven and yet was there all the time. There are many things which are hard to understand in the Bible but you can be sure that God never expects us to believe impossibilities.
Over and over again you hear it said that the Gospel is so simple a child can understand it. And I agree. But how can that be the case with the teaching of the trinity? Not only do children not understand it, but our best theologians cannot even explain it. However, the thought that God sent His Son to this earth to die for you and me is easy to comprehend when we believe the simple Bible statement that Jesus is truly the Son of God! Not one of three mysterious beings making up “one God.”
How can you possibly believe that Jesus is NOT the begotten Son of the eternal Father and then share John 3:16 with others in the hope of inviting them to take part in eternal salvation. Doesn't John 3:16 become a lie the moment you deny He is a Son? A metaphor did not send a metaphor to save us. A Father sent us His Son to save us.
John 3:16 “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
2 John 1:3 “Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love.”
