read the NT - James the Just was the leader of the Apostles after the crucification = Peter and John were, basically, head councilors - and Paul referred to the three, derisively as "The so-called Pillars of the Church."
But there's a problem, see, James was the BLOOD brother of Jesus - and we must shove him aside, along with other BLOOD relatives who were appointed, one after the other, to take James' position after he was thrown from the parapet of the Temple by Temple Priests and stoned to death n the courtyard - in 62AD. that would show a Blood line succession - and that would negate the power take over by the Roman Gov't that became the Roman Catholic Church over 300 years after Jesus...Shhhh
