I have no doubt that Jesus exsisted. That much is evident.
What is in question is his divinity.
Was it established long after his death when the gospels were written?
Well, according to traditional Biblical scholars, the Gospels were written shortly after Jesus' death, the latest being the gospel of John in the 90s A.D.
Was it a rumor that spread across the land of his alleged resurection that in time developed into a religion?
Had it been, it could have been easily squashed.
If it had just been a spiritual resurrection, the enemies of the New Testament church would have put the body of Jesus on a cart, walked it right down the streets of Jerusalem and killed Christianity, not just in the cradle but in the womb. There would have been no New Testament church, if they had the body. - Josh McDowell,
Evidence that Demands a Verdict, also from the "Who is This Jesus? Is He Risen" special.
I would suggest that, even without Jesus' body, had Jesus not resurrected, all the Romans would have had to do was find the disciples and torture them, until they confessed that the whole thing was a fraud. The disciples did NOT come to the tomb to get His body. According to the gospel of Matthew, the guards at the tomb went to the Pharisees for help, because Jesus was gone and they faced the death penalty for letting that seal on the tomb get broken.
All they had to do was make sure that Jesus' body stayed in the tomb until Monday (or whatever the corresponding day was back then); then, both they and the Pharisees' could have simply stated that His body was stolen.
Plus, Paul states that Jesus appears to the disciples and to 500 witnesses, over the span of about six weeks.
Was he in a coma on the cross and did he "miraculously" come out of the coma 3 days later and consequentially was viewed by those who ignorant to comas as rising from the dead?
Here's what Dr. Gary Habermas from the special,
Who Is This Jesus? Is He Risen, and author of the book
The Historical Jesus, had to say on the claim that Jesus may not have actually died on the cross (aka the “Swoon Theory”):
The Swoon Theory is held by virtually no reputable scholars today. Death by crucifixion is essentially death by asphyxiation; you don’t get down off the cross alive. Plus, there’s the nature of the spear, which enters the chest cavity through the rib cage and penetrates the heart. In short, it would have killed Him, if He weren’t already dead.In the Gospels, Joseph of Arimithea asks Pilate for the body of Jesus. When Pilate hears of Jesus’ death, he is surprised that He died so, relatively speaking, quickly (remember that crucifixion was designed to maximize suffering). So, Pilate sent someone to confirm that Jesus was indeed dead, before releasing custody of His body to Joseph. I'd hardly classify Joseph or Pilate as "ignorant".
And, you will recall that, when the women go to the tomb, they go with spices with the intent of finishing the burial process. All the while, they are contemplating how they are going to move the stone, which has since been sealed with a Roman seal and had guards there, due to the Pharisees’ fear that the disciples would steal Jesus’ body and then claim that He’d risen from the grave, as Jesus said He would.
did the writers of the gospel embelish this rising from the dead long after Jesus died of natural causes. Were the goshpels then altered by those who could see the begginings of a new and powerful religion?
The power of Christianity and the foundation of it is the Resurrection. Remember the disciples saw Jesus die firsthand and were scared to death. They didn't believe it, when the women reported that He'd risen. Some disciples didn't believe it, even when the other disciples saw the risen Christ (the most famous of which is Thomas).
that's the problem with finding out facts fromt he past. It's difficult to be accurate unless you were there to wittness it.
That's why the closer ancient manuscripts are to the events they describe, the more likely they are to be authentic. No other ancient documents can match the Gospels in that category.
Was it all really just a political struggle between the house of herod and teh house of David for the crown?
Nope! Jesus made it clear, that He did NOT come to establish an earthly kingdom. Despite that, some of His disciples didn't get it. The mother of two disciples was politicking to get her sons cushy positions in what she perceived to be Jesus' new earthly kingdom. Some believe that the motive behind Judas' betrayal of Jesus was forcing His hand, so that He would start a crusade to crush Rome and set up shop (with Judas having a nice desk job as treasurer; he was, after all, the one who held the bag).
