Nicene Creed - Nomenclature

Nomenclature

There are several designations for the two forms of the Nicene creed, some with overlapping meanings:

• Nicene Creed or the Creed of Nicaea is used to refer to the original version adopted at the First Council of Nicaea (325), to the revised version adopted by the First Council of Constantinople (381), to the Latin version that includes the phrase "Deum de Deo" and "Filioque", and to the Armenian version, which does not include "and from the Son", but does include "God from God" and many other phrases.
• Niceno-Constantinopolitan Creed can stand for the revised version of Constantinople (381) or the later Latin version or various other versions.
• Icon/Symbol of the Faith is the usual designation for the revised version of Constantinople 381 in the Orthodox churches, where this is the only creed used in the liturgy.
• Profession of Faith of the 318 Fathers refers specifically to the version of Nicea 325 (traditionally, 318 bishops took part at the First Council of Nicea).
• Profession of Faith of the 150 Fathers refers specifically to the version of Constantinople 381 (traditionally, 150 bishops took part at the First Council of Constantinople).

In musical settings, particularly when sung in Latin, this Creed is usually referred to by its first word, Credo.
