I think the question is for synodality. If so, it is a theological term meaning relative to the synod. It means meeting of bishops, council. By extension church meeting, ecumenism . According to Pope Francis it is "an ecumenical challenge", for "the commitment to build a synodal Church, -a mission to which we are all called, each in the role entrusted to him by the Lord, is gaimed on ecumenical implications" ( Taken from the Address on the occasion of the 50th Anniversary of the Founding of the Synod of Bishops, 17 October 2015 ).
