The supposed “dual nature” of Christ is never stated in the Bible and contradicts the Bible and the laws of nature that God set up. Nothing can be 100% of two different things. Jesus cannot be 100% God and 100% man, and that is not a “mystery” but it's a contradiction and a talk of nonsense. A fatal flaw in the “dual nature” theory is that both natures in Jesus would have had to have known about each other. The Jesus God nature would have known about his human nature, and (according to what the Trinitarians teach) his human nature knew he was God, which explains why Trinitarians say Jesus taught that he was God. The book of Hebrews is wrong when it says Jesus was “made like his brothers in every respect” if Jesus knew he was God (Hebrews 2:17). Jesus was not made like other humans in every way if Jesus was 100% God and 100% human at the same time. In fact, he would have been very different from other humans in many respects.
For example, in his God nature he would not have been tempted by anything (James 1:13), and his human part would not have been tempted either since his human nature had access to that same knowledge and assurance. It is written he was tempted in every way like we all are (Hebrews 4:15). Furthermore, God does not have the problems, uncertainty, and anxieties that humans do, and Jesus would not have had those either if he knew he was God. Also, Luke 2:52 says Jesus grew in wisdom, but his human part would have had access to his God part, which would have given him infinite and inherent wisdom. Hebrews says Jesus “learned obedience” by the things that he suffered, but again, the human part of Jesus would have accessed the God part of him and he would not have needed to learn anything.
Kenotic Trinitarians claim that Jesus put off or limited His God nature, but that theology only developed to try to reconcile some of the verses about what Christ experienced on the earth. The idea that God can limit what He knows or experiences as God is not taught or explained in Scripture, and Kenotic Trinitarianism has been rejected by orthodox Trinitarians for exactly that reason. The very simple way to explain the “difficult verses” that Kenotic Trinitarians are trying to explain about Christ’s human experiences is to realize that Jesus was a fully human being, and not both God and man at the same time. Some assert we have to take the Trinity “by faith” but that is not biblical either.
