We profess the Catholic Faith in communion with the Supreme Pontiff and our local ordinary. A classic expression of our belief can be found 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; on the third day he rose again from the dead; he ascended into heaven, and is seated at the right hand of God the Father almighty; from there he will 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.
For a deeper understanding, one useful resource (in Q&A format) is the Compendium of the Catechism of the Catholic Church. Responses to common queries regarding Catholic belief can be found at Catholic Answers.
