Did Jehovah destroy Jesus's pre-human spiritual body?
God the Son, the Word, was not destroyed. Jesus was a divine person who assumed a human nature. He was God-man.
The divine Person of Jesus was still fully God, who chose a veiled glory.
Christ possessed equality with God prior to His incarnation, and then for a time veiled that glory, being always God in all of the co-equal attributes, but in the incarnation never using His Godly powers to better Himself. He was fully God, fully man, God taking on the likeness of sinful flesh (Rom 8:3), not a man adding Godliness. (Strong and Vine’s, 42)
As Jesus could not have two bodies at the same time, his "spiritual body" could not continue to exist while he was "human."
Totally false. He was, and is, God-man. Fully God, fully man. The mystery of the union is just that, and accepted as mystery by the church.
Maybe you're arguing against the Watchtower in this thread? Are you taking the Christians' side, or the WBTS?
It is said that Jesus came to earth as a human, but if his spirtual body was destroyed, what was left to "come" to earch?
Jesus didn't come to earth as a human. The Word, God the Son, came to earth and assumed a human nature and became Jesus at conception.
Jesus the God-man as God-man didn't exist until Mary conceived him.
