Conciliarism is a term used to refer to the system of governance that assigns the highest authority in the church to an ecumenical council, rather than the Pope. However, there are several other words or phrases that can be used as synonyms for conciliarism. These include collegiality, synodality, councilorism, and councilarianism. All of these words share the same basic meaning of emphasizing the importance of councils or committees rather than a single authority figure in a religious hierarchy. They suggest a more democratic and representative approach to decision-making, which is essential for any institution that seeks to create a fair, just, and equitable system.
