Such we have in Moses and the prophets, and above all in Christ.

Now, all those things are to be believed which are written in the word of God, or handed down by tradition, which the Church by her teaching has proposed for belief.
"No one can be justified without this faith, nor shall any one, unless he persevere therein to the end, attain everlasting life.

Hence God, through his only-begotten Son, has established the Church as the guardian and teacher of his revealed word.

For only to the Catholic Church do all those signs belong which make evident the credibility of the Christian faith.

Nay, more, the very Church herself, in view of her wonderful propagation, her eminent holiness, her exhaustless fruitfulness in all that is good, her Catholic unity, her unshaken stability, offers a great and evident claim to belief, and an undeniable proof of her divine mission.
