CREED comes from the Latin credo, "I believe." From the earliest days of the Church, creeds have been living confessions of what Christians believe and not simply formal, academic, Church pronouncements. Such confessions of faith appear as early as the New Testament, where, for example, Saint Paul quotes a creed to remind Timothy, "God was manifested in the flesh.. ." (1 Timothy 3:16). The creeds were approved by Church councils, usually to give a concise statement of the truth in the face of the invasion of heresy.
The most important creed in Christendom is the Nicene Creed, the product of two Ecumenical Councils in the fourth century. Fashioned in the midst of a life-and-death controversy, it contains the essence of New Testament teaching about the Holy Trinity, guarding that life-giving truth against those who would change the very nature of God and reduce Jesus Christ to a created being rather than God in the flesh. The creeds give us a sure interpretation of the Scriptures against those who would distort them to support their own religious schemes. Called the "Symbol of Faith" and confessed in many of the services of the Church, the Nicene Creed constantly reminds the Orthodox Christian of what he personally believes, keeping his faith on track.
