Which council is known for its decisions impacting the governance of the Church?

The Council of Laodicea is recognized for its significant contributions to the governance of the Church, particularly in the 4th century. While it addressed various issues, it focused on ecclesiastical order and the regulation of church practices, including the role of bishops, the proper conduct of clergy, and the establishment of specific church canons. This council played a crucial role in shaping the administrative framework of the early Church and set precedents for governance that influenced subsequent councils and ecclesiastical structure.

The relevance of this council in terms of governance is tied to its canons, which provided guidelines on the operations of the local churches and the authority of church leaders. This was part of the early effort to unify and standardize practices across the Christian community, contributing to a more organized and hierarchical structure within the Church.

Other councils, such as Nicaea, Jerusalem, and Trent, addressed various theological issues and doctrinal definitions but are more prominently associated with defining beliefs and practices rather than specifically focusing on the governance and administrative aspects of the Church in the way the Council of Laodicea did.
