He was upset that Paul wanted to do away with circumcision and kosher.
He was upset that these new congregations were not Jewish...... Cephas thought that this was for the Jews, imo.
He didn't disagree fundamentally with Paul about the crucifixion. It's not said that he did.
Cephas didn't have to agree with any of Paul's ideas........ neither of them was there, and Paul never met with Jesus after that time like Cephas did.
All Paul had was belief.
James is recorded as Jesus's brother; he 'took the reins' after Jesus's death. To reject the death on the cross is all speculation that is not supported by the New Testament, imo
So -- unless there's anything new ...?
There's always something new if the info hasn't been studied in deep depth. I learned something new during this last week after decades of study.
The person who knows it all usually does not, imo.
Cephas, Andrew, John, James, Levi and all the Disciples........ were brothers to Jesus.
Who James was is still unclear to me. All the disciples were brother to Jesus.
Mark {3:32} And the multitude sat about him, and they said unto him, Behold, thy mother and thy brethren without seek for thee. {3:33} And he answered them, saying, Who is my mother, or my brethren? {3:34} And he looked round about on them which sat about him, and said, Behold my mother and my brethren! {3:35} For whosoever shall do the will of God, the same is my brother, and my sister, and mother.
