“I believe in one God, the Father almighty, maker of heaven and earth, of all things visible and invisible.” “Our profession of faith begins with God, for God is the First and the Last, the beginning and the end of everything. The Credo begins with God the Father, for the Father is the first divine person of the Most Holy Trinity; our Creed begins with the creation of heaven and earth, for creation is the beginning and the foundation of all God's works” (CCC, 198). These words, which we say every Sunday during Mass, are an expression of our faith. This is the Niceno-Constantinopolitan, or Nicene Creed, formulated at the Councils of Nicea in 325 and Constantinople in 381.

We have today’s saint, St. Leander of Seville, to thank for this addition to the liturgy; he was bishop of Seville in the 6th century. The Visigoths had overrun Spain and were converted through the Arian heresy, which stated that Jesus was the first creation of God, but was not God. The Church was separated between Arian and Catholic bishops and peoples. St. Leander introduced the Creed as a way to help reinforce the orthodox Catholic faith among the people in 589 at the Third Council of Toledo. This brought about the conversion of the Visigoth King of Spain and the reconciliation of the Arian faction to the true faith of the Church. This version of the Creed also introduced the filioque clause, that the Holy Spirit proceeded from the Father and the Son, which spread to the rest of Latin-speaking Catholicism and was accepted throughout the Western Catholic Church by 1000.

It is necessary to know the faith in order to live the faith and to bring others to the truth, who is Jesus Christ. St. Leander, pray for us.
