We are required to know and to believe:

• • That there is one supreme, eternal, infinite God, the Creator of heaven and earth.
  
  
• • That the good will be rewarded by him for ever in heaven, and that the wicked who die unrepentant will be punished forever in hell.
  
  
• • That in the Holy Trinity there are three Persons, coeternal, coequal: God the Father, God the Son, and God the Holy Spirit.
  
  
• • That the Second Person of the Holy Trinity became man and died on the cross to save us.
  
  
• • The tenets of the Apostles' Creed.
  
  
• • In the Commandments of God and of the Church.
  
  
• • That the seven sacraments were instituted by Christ to give us grace; especially, that Baptism is necessary and that the Eucharist is a pledge of  our  future glory.
             
• • That Sacred Tradition and Sacred Scripture, which together form one sacred deposit of the Word of God, are entrusted to the Church.
  
  
• • Whatever God teaches us by his Church, who in her teaching cannot deceive us or be deceived.
  
  
• " ‘The Roman Pontiff, head of the college of bishops, enjoys [this] infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful, he proclaims by a definitive act a doctrine pertaining to faith or morals. . . . The infallibility promised to the Church is also present in the body of bishops when, together with Peter's successor, they exercise the supreme ‘Magiste­rium,' above all in an Ecumenical Council. When the Church through its supreme Magisterium proposes a doctrine ‘for belief as being divinely revealed' and as the teaching of Christ, the definitions ‘must be adhered to with the obedience of faith.'"15
