Question: What is the history of the Credo?
Answer: The Credo or "creed" was last to be added to the Mass. It exists in three forms: Apostles, Nicene, and Athanasian. The history of its evolution is quite complex. The version that is commonly used today is the Nicene Creed. It was approved for use by the Council of Nicea in 325. From there, it was introduced to Spain by the Council of Toledo in 589, the eucharistic liturgy in Constantinople in the 6th century, and the Gallican rite in France by Charlemagne's liturgical advisor. In 1014, German Emperor Henry II insisted Pope Benedict VIII to introduce it to the Roman rite. Finally, in the 11th century, the Credo was included in the Mass Ordinary.
