Pope Francis’s three-week Synod on the Family began on Sunday. Most of the 279 ‘Synod Fathers’ are senior bishops, many of them cardinals. They have no authority to change any aspect of Catholic teaching or pastoral practice. They are discussing the ‘hot button’ issues of communion for the divorced and remarried and the spiritual care of gay Catholics — but, once the meeting is over, power will rest entirely in the hands of the Pope.
