The Catholic Church, its authority and mission.
I am to know what God has revealed by the testimony, teaching, and authority of the Catholic Church.
Jesus Christ gave the Catholic Church divine authority to teach when he said, "Go therefore, make disciples of all the nations".
The chief things which God has revealed are contained in the Apostles' Creed.
I believe in God, the Father almighty, Creator of heaven and earth; and in Jesus Christ, his only Son, our Lord; who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died and was buried. He descended into hell; the third day he rose again from the dead; he ascended into heaven; and sits at the right hand of God the Father almighty; from thence he shall come to judge the living and the dead. I believe in the Holy Spirit; the holy Catholic Church; the communion of saints; the forgiveness of sins; the resurrection of the body; and life everlasting. Amen.
The Apostles' Creed is divided into twelve parts or articles.
The ninth article of the Creed is, "the Holy Catholic Church, the communion of saints".
The Catholic Church is the union of all the faithful under one Head.
The Head of the Catholic Church is Jesus Christ our Lord.
The Church has a visible Head on earth - the Bishop of Rome, who is the Vicar of Christ.
