Trinitarians claim that Jesus became the Son of God by His birth in Bethlehem. If this were true, then consider the following. Matthew 1:18 says that “Mary was found with child of the Holy Ghost.”
So if the Holy Spirit impregnated Mary, and the Holy Spirit was an individual being as the Trinity doctrine claims, then the Holy Spirit must be the father of Christ.
Yet my Bible tells me that God the Father is the father of Christ. So how can this be? Because the Holy Spirit is not another god called “god the spirit” but is the “Spirit OF God” or the “Spirit OF the Father” as the Bible tells us.
The phrase “god the holy spirit” occurs nowhere in Scripture, but originated from the creators of the Trinity doctrine being the Roman Catholic Church in 381 AD, more than 200 years AFTER the Bible was written.
Note below that SOP informs us that Jesus was already the literal SON OF GOD before He came to earth and so He became the Son of God in a NEW SENSE.
“Christ brought men and women power to overcome. He came to this world in human form, to live a man amongst men. He assumed the liabilities of human nature, to be proved and tried. In His humanity He was a partaker of the divine nature. In His INCARNATION He gained in a NEW SENSE THE TITLE OF THE SON OF GOD. Said the angel to Mary, “The power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God” (Luke 1:35). While the Son of a human being, He became the SON OF GOD IN A NEW SENSE. Thus He stood in our world--the SON OF GOD, yet allied by birth to the human race.” — (E.G. White, ST, Aug 2, 1905)
“O what a gift God has made to our world! The Word was made flesh and dwelt among us. GOD SENT HIS OWN SON in the likeness of sinful flesh, liable to physical infirmities, tempted in all points like as we are. HE WAS THE SON OF THE LIVING GOD. His PERSONALITY did NOT begin with His INCARNATION in the flesh.” — (E.G. White, Lt77, Aug 3, 1894)
“The more we think about Christ's becoming a babe here on earth, the more wonderful it appears. How can it be that the helpless babe in Bethlehem's manger is still the DIVINE SON OF GOD?” — (E.G. White, YI, Nov 21, 1895)
“The dedication of the FIRST-BORN had its origin in the earliest times. God had promised to give the FIRST-BORN OF HEAVEN to save the SINNER.” — (E.G. White, DA, p. 51)
