9) God is eternal, but Jesus had a beginning
"God was not born; He is eternal. In contrast to the eternal God, Christ is “begotten,” that is, born. Jesus Christ had a beginning. Jesus is never called “God the Son” in the Bible, but he is called the “Son of God” more than 50 times, and a “son” has a beginning. The very fact that Jesus is the “Son of God” shows he had a beginning. Trinitarian doctrine denies this and invents the phrase “eternally begotten.” But “eternally begotten” is not in the Bible; it was invented to help explain the Trinity but is actually a nonsensical phrase; the words are placed together but they cancel each other out. “Eternal” means without beginning or end, whereas something that is “begotten,” by definition, has a beginning.
We cannot approach the Bible with wisdom and “reason together” with God (Isa. 1:18) if we must invent and use non-biblical phrases to support our theology. Also, additional evidence that Jesus had a beginning is provided in verses such as Matthew 1:18, which speaks of the “beginning” of Jesus Christ (see commentary on Matt. 1:18), and Colossians 1:15 (covered above), which says that Jesus is part of God’s creation. The Bible calls Jesus the “Son” of God for the simple reason that he had a beginning. Jesus had been part of God’s plan since the foundation of the world, but he began his actual life when God “fathered” him and Mary conceived him in her womb."
