Christ The Cause of Division

Many of the people therefore, when they heard this saying, said, Of a truth this is the Prophet. Others said, This is the Christ. But some said, Shall Christ come out of Galilee? Hath not the scripture said, That Christ cometh of the seed of David, and out of the town of Bethlehem, where David was? So there was a division among the people because of him. (John 7:40-43)

Even the Apostle Paul was not immune to strife. He and Barnabas locked horns one day, and (so far as we can know) never worked together again.
