Nicene-Constantinople Symbol of Faith

History and Development

The Nicene-Constantinople Symbol of Faith, also known as the Credo or "I believe," is a strict dogmatic formula of faith introduced at the Second Ecumenical Council in 381. It was approved at the Fourth Ecumenical Council in 451 as a full disclosure of the doctrine of the Trinity.

The development of this symbol of faith began with the First Ecumenical Council of Nicaea in 325, where the Nicene Creed was composed. The Second Ecumenical Council in 381 expanded and supplemented the original creed, creating the Constantinople or the Creed of the Second Ecumenical Council. Although this council did not approve it mandatory, it became a widely accepted formula of faith.

Usage and Significance

The Nicene-Constantinople Symbol of Faith has been used in various Christian denominations since its creation in the 4th century. It is considered the most common Christian way to confess the faith and has been adopted by Eastern Orthodoxy, Catholicism, Jacobite, ancient Eastern national churches, Assyrian, English, Lutheran, and most other Protestant churches.

Purpose and Function

The symbol of faith was created to preserve unity in faith, protect believers from deviations, and bring new believers into faith. During the period of persecution against Christianity, the texts of these symbols were secret, but all Christians had to know the text of the symbol by heart. This was sometimes used to check whether a person was a Christian.

Terminology

The term "Great faith" is used by most historical clergy and capads in reference to this symbol of faith. The Nicene-Constantinople Symbol of Faith is also known as the Credo or "I believe," reflecting its role as a statement of faith.
