Nicene Creed
We believe in on God, the Father, the Almighty, maker of heaven and earth, of all that is seen and unseen. We believe in one Lord, Jesus Christ, the only son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, note made, one in being with the Father. Through him all things were made. For us men and our salvation he came down from heaven: by the power of the Holy Spirit he was born of the Virgin Mary, and became man. For our sake he was crucified under Pontius Pilate; he suffered, died, and was buried. On the third day he rose again in fulfillment of the Scriptures; he ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end. We believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son. With the Father and the Son he is worshiped and glorified. He has spoken through the Prophets. We believe in one holy catholic and apostolic Church. We acknowledge one baptism for the forgiveness of sins. We look for the resurrection of the dead, and the life of the world to come. Amen. (325 A.D.)

The very name of the Church is Catholic, that is, universal…It was St. Ignatius (50-107 A.D.) appointed Bishop of Antioch by Saint Peter, who first used the Greek word Katholicos, meaning “universal,” when referring to the Church founded by Christ; this he did to distinguish the True Church, already being preached throughout the world, from heretical churches that had arisen.
