As JW's we swallowed such concoctions for years - without a single Scripture provided as proof!
w71 12/15 p. 759 - "Apparently, the apostle Peter was the chairman of the governing body on the festival day of Pentecost of 33 C.E., and the disciple James, the half brother of Jesus Christ, was the chairman at a later date, according to the account in Acts of Apostles. From this, and from what historical evidence there is available, the chairmanship of the governing body rotated."
Can someone point me to the to the account in Acts of Apostles - I'm having trouble finding it! 🤣
