People did not bow down before Jesus in His earthly life. In Acts it does not say they bowed down to Him as He ascended back to the Father. It says they worshiped Him. You are now conflating bowing to worshiping and the subject is worship---which you dismiss as a buzzword.
There was a custom in those days of bowing to those in authority and in respect, much as we shake hands. And every knee shall bow before Jesus as Lord. And Lord is God. Even you acknowledge that there is only one Lord.
No. Nathan was following the custom of kneeling before the king as a form of honor and submission. When we kneel before the Great King it is worship for only He is worthy of worship. And who is King of kings and Lord of lords? Rev 17:14 They will make war on the lamb, and the Lamb will conquer them, for he is Lord of lords and King of kings, and those with him are called and chosen and faithful.
The same name is applied to God the Father in 1 Tim 6:12-16 Fight the good fight of the faith. Take hold of the eternal life to which you were called and about which you made the good confession in the presence of many witnesses. I charge you in the presence of God, who gives life to all things, and of Christ Jesus, who in his testimony before Pontius Pilate made the good confession, to keep the commandment unstained and free from reproach until the appearing of our Lord Jesus Christ, which he will display at the proper time -- he who is the blessed and only Sovereign, the King of kings and Lord of lords, who alone has immortality , who dwells in unapproachable light, whom no one has ever seen or can see. To him be honor and eternal dominion. Amen.
The grave error is that you continue to argue a straw man. Trinitarianism states plainly that Jesus is a human. Before the incarnation He is known as the Word, the Son, the Rock, the Pillar of Fire, the cloud, the Angel (messenger) of the Lord and in the incarnation, His name is Jesus. Trinitarianism does not say that God died. It says the man Jesus died. But FYI what is eternal and self existent and spirit, and immortal, cannot die.
That is not a better question. It is a way of not answering the ones that were asked. When you answer them, I will answer the ones you asked.
Here is another question. Be gracious enough to answer it. Does it ever give you pause, that a word like worship is even understood by children with no ambiguity, and yet, here comes a religion that has to make it into a puzzle and find another meaning for it other than its meaning? Have you ever questioned why such a silly thing became of supreme importance in defending that religions teaching on who Jesus is? Why their teaching made it necessary? Put on your thinking cap.
