Ecumenical Councils are gatherings of church leaders from various Christian denominations aimed at addressing critical theological and doctrinal issues. These councils play a significant role in shaping the beliefs and practices of the Christian faith, often resulting in important creeds and declarations that guide the church's teachings. Throughout history, notable Ecumenical Councils, such as the First Council of Nicaea in 325 AD, have sought to unify the church and resolve disputes. They serve as a platform for dialogue and collaboration among different branches of Christianity, promoting unity and understanding within the faith community.
