No he wasn't. He is the Son of God, born without sin.
No different from anyone else: Heb 2:17 "Wherefore in all things it behoved him to be made like unto his brethren,"
He was BORN "God's monogenes Son."
You said he was created God's son, by I asked what criteria constituted Christ being so created, and all you can do is point me to some Übermensch, some superhero, as if Christ was not like his brethren.
No, Jesus came from God. God is his Father.
That much is a lie as you say Jesus had no pre-existence. Alternatively "God" infers "God's plan" in yiour vocabulary.
No it doesn't.
Since I do not believe heaven is God's plan, you're beating on a strawman.
It's what the bible infers you believe:
1 John 1:2 "The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us"
If the "eternal life that was with the Father," i.e. in heaven, and has now appeared to us, was just "God's plan," then essentially, all we ever had was God's created superhero. All eternal life is just "God's plan".
So heaven "I came down from heaven" has no actual reality. "Coming down from heaven" is "fulfulling God's plan." The very concept of heaven & eternal life is reduced to "God's plan."
And besides which, since you reckon the risen Jesus is still "a man," a real man, like us, then heaven doesn't exist at all in biblical terms, because the bible says it is a spiritual abode, not one of flesh, which is the pagan conception. Your heaven seems to be pagan.
