Christian Councils are gatherings of church leaders and theologians aimed at addressing important issues within the Christian faith. These councils often discuss doctrinal disputes, church practices, and matters of governance. Notable examples include the Council of Nicaea in 325 AD, which established foundational Christian beliefs, including the nature of Jesus Christ. The decisions made during these councils can lead to the formulation of creeds, which are formal statements of faith. Councils also play a crucial role in resolving conflicts and promoting unity among different Christian denominations, helping to shape the development of Christianity throughout history.
