All these ideas come together in 1 Peter, which I think is genuine and sums up Jewish Christianity well, and answers the historical vs. mythical Jesus question in 3:18-22:
For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. After being made alive, he went and made proclamation to the imprisoned spirits— to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built. In it only a few people, eight in all, were saved through water, and this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God. It saves you by the resurrection of Jesus Christ, who has gone into heaven and is at God’s right hand—with angels, authorities and powers in submission to him.
The word for "body" in 3:18 above is sarx, which is defined as "flesh, body, human nature, materiality," and Peter contrasts it with spirit:

1 Peter 4:1-7:
Therefore, since Christ suffered in his body, arm yourselves also with the same attitude, because whoever suffers in the body is done with sin. As a result, they do not live the rest of their earthly lives for evil human desires, but rather for the will of God ... But they will have to give account to him who is ready to judge the living and the dead. For this is the reason the gospel was preached even to those who are now dead, so that they might be judged according to human standards in regard to the body, but live according to God in regard to the spirit. The end of all things is near.
1 Peter 5:1
... I appeal as a fellow elder and a witness of Christ’s sufferings who also will share in the glory to be revealed.
1 Peter 1:4-5:
This inheritance is kept in heaven for you, who through faith are shielded by God’s power until the coming of the salvation that is ready to be revealed in the last time.
1 Peter 1:13:
Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming.
This is all in keeping with everything I cited in the posts above. And I think 1 Peter 2:4-7 offers additional evidence that Jesus was a human being:
As you come to him, the living Stone—rejected by humans but chosen by God and precious to him— you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.
Not only is this in keeping with the Dead Sea Scrolls (which are pre-70 CE and also espouse the idea of being a "spiritual house to be a holy priesthood, offering spiritual sacrifices"), it underlines that Jesus was rejected by humans, like in Mk. 8:31 ("He then began to teach them that the Son of Man must suffer many things and
be rejected by the elders, the chief priests and the teachers of the law, and that he must be killed and after three days rise again").
I think this is "it" in a nutshell, from someone who was there, like in 1 John 1:1-3 (who I think was the pillar John):
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched—this we proclaim concerning the Word of life. 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. We proclaim to you what we have seen and heard, so that you also may have fellowship with us.
