An Ecumenical Council is a formal assembly of church leaders and theologians from various Christian denominations. These councils aim to address important theological, doctrinal, and organizational issues within the Christian faith. They play a crucial role in promoting unity and resolving disputes among different branches of Christianity. Historically, significant Ecumenical Councils have taken place, such as the Council of Nicaea in 325 AD, which established foundational Christian doctrines. These gatherings often result in official statements or creeds that guide the beliefs and practices of the participating churches, fostering a sense of shared faith and purpose.
