First of all I've said this plenty of times that the Apostle John at 1John 4:9 called the person who became Jesus Christ, the Only Begotten Son of God before he became human. So the person who came to the world of mankind as a human was the Only Begotten Son of God while in heaven with his Father who is God before he came to the world of mankind as Jesus Christ. Jesus was in God's form in heaven before he came to the world of mankind. Stay alert this scripture doesn't say Jesus was God, it says he was in God's form. Philippians 2:5-7
Regardless of what any council or man has said about Jesus’ nature, the only reliable source of religious truth is the Bible. This Word reveals that Jesus is God’s Son and as such he was not and is not God. Jesus himself said: “I am God’s Son.” To Mary the angel Gabriel said: “What is born will be called holy, God’s Son.” Nothing is said of a God-man or a man-God. Nowhere in the Bible is Jesus called a “God-man” or “God incarnate.” Such assumptions are strictly human illusions tainted with paganism. John 10:36; Luke 1:34,35; 2:21
The scriptures show us at Revelation 3:14 that Jesus is referred to as the beginning of the creation by God. I have never believed God to be a part of creation but apart or separate of creation, yet not only is Jesus said to be the beginning of creation at Revelation 3:14 but at Colossians 1:15 he is said to be, "the firstborn of creation." Now why would Jesus be said to be, "the firstborn of creation," when such a phrase when used regarding animals or humans in the scriptures show what is said to be firstborn of, is part of that group. What I mean is when you say something like, "the firstborn of," Egypt, the scriptures are talking about people in that nation called Egypt. When the scriptures say, "the firstborn of," Israel, the scriptures are talking about people in the nation called Israel. So going by how the scriptures use the phrase, "the firstborn of," Jesus is a person who is a part of creation. As I said God isn't a part of creation, but the Only Begotten Son of God is.
