The Fifth Ecumenical Council, also known as the Second Council of Constantinople, took place in 553 AD. It was convened by Emperor Justinian I to address various theological disputes, particularly those related to the nature of Christ and the teachings of certain theologians. The council aimed to promote unity within the Christian Church and clarify doctrinal issues. During the council, the bishops condemned the writings of three theologians, known as the Three Chapters, which were seen as heretical. This decision was significant in shaping the relationship between the Eastern Orthodox Church and the Western Church, influencing future theological discussions and ecclesiastical politics.
