The Council of Nicaea was a significant gathering of Christian bishops convened in 325 AD by the Roman Emperor Constantine. Its primary purpose was to address the growing divisions within Christianity, particularly the controversy surrounding the nature of Jesus Christ and his relationship to God the Father. The council produced the Nicene Creed, a statement of faith that affirmed the belief in the Trinity. The council also established key decisions regarding the date of Easter and addressed various church practices. It marked a pivotal moment in the development of early Christianity, helping to unify beliefs and practices across the growing Christian community.
