[2] As early as the fourteenth century, opposition to this centralization of papal authority had developed, with Bishop Guillaume Durand proposing at the Council of Vienne that local hierarchies and regional synods be strengthened.
[2] This opposition to centralization was tested when a group of cardinals, allied with secular rulers, called a council to resolve the Great Schism of the Western Church (1378 – 1417), in which several rivals had claimed to be pope.
"[2] Bishops who objected to this recent consolidation of papal authority proposed at the Second Vatican Council to use the traditional collegial model to limit the centralizing tendencies of the Roman Curia; unlike conciliarists, who had maintained that an ecumenical council was superior to the Pope, advocates of collegiality proposed bishops only act “with and under the Peter [i.e. the Pope]” (cum et sub Petro).
[14] In September 2017, Pope Francis issued the motu proprio, Magnum principium, in which he amended the 1983 Code of Canon Law to increase the responsibility of national conferences of Bishops for liturgical translations.
The change has been described “as one of Pope Francis’s strongest moves yet in terms of fostering greater collegiality in the Catholic Church.”[15] In September 2018, by the apostolic constitution Episcopalis communio,[16][17] Pope Francis introduced a more direct process whereby a final synodal document becomes a part of the Church's magisterium simply by receiving papal approval.
