If Jesus was a real person, there is most assuredly a difference between what he actually said versus what was written that he said.
The idea of a innocent man persecuted and murdered by religious zealots is still is a lesson that needs to be learned by every generation.
The problem, is more often than not, "the religious" that are usually at fault.
The story of Jesus is filled with many truths and a many falsehoods.
Matthew 1:5+6 (KJV)
5 These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
6 But go rather to the lost sheep of the house of Israel.
Mark 16:15+19 (KJV)
15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
19 So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.
After his resurrection, his ministry changed from Israel to the world.
This leaves the question... then, are the Gospels addressed to Israel
or the church?
