Which verses are used by those who deny the divinity of Christ?

Jesus says, “For My Father is greater than I” (John 14:28), because He was embodied and took the form of a slave.

The apostle Paul says, “who, being in the form of God, did not consider it robbery to be equal with God, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross” (Phil. 2:6–8).

“Most assuredly, I say to you, the Son can do nothing of Himself, but what He sees the Father do; for whatever He does, the Son also does in like manner” (John 5:19). This expression does not imply that the Son depends on the Father because He is inferior to the Father. Rather, it reveals their equality and the harmony of their cooperation together, the unity of their will, and the unity of their authority in all things. They share one essence with the Holy Spirit, with whom they cooperate in action.

The Lord Christ says, “And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent” (John 17:3). This expression does not refute the equality of the Father and the Son, because the phrase, “the only true God” excludes false gods, not the Son.

The Lord Christ refers to Himself as the “Son of Man” (Matt. 8:20; 9:6; 11:19; etc.) because He wants to affirm that He had indeed become human; contrary to those among the Gnostics who claimed that He had no real body, but only appeared to have a body.

The apostle Paul says, “the firstborn over all creation” (Col. 1:15). He did not say, “The firstborn of those who were created.” Rather, “firstborn” refers here to His birth from the Father before all creation.
