CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 67–71

67 Throughout the ages, there have been so-called "private" revelations, some of which have been recognized by the authority of the Church. They do not belong, however, to the deposit of faith. It is not their role to improve or complete Christ's definitive Revelation, but to help live more fully by it in a certain period of history. Guided by the Magisterium of the Church, the sensus fidelium knows how to discern and welcome in these revelations whatever constitutes an authentic call of Christ or his saints to the Church.

Christian faith cannot accept "revelations" that claim to surpass or correct the Revelation of which Christ is the fulfillment, as is the case in certain non-Christian religions and also in certain recent sects which base themselves on such "revelations".

68 By love, God has revealed himself and given himself to man. He has thus provided the definitive, superabundant answer to the questions that man asks himself about the meaning and purpose of his life.
69 God has revealed himself to man by gradually communicating his own mystery in deeds and in words.
70 Beyond the witness to himself that God gives in created things, he manifested himself to our first parents, spoke to them and, after the fall, promised them salvation (cf. Gen 3:15) and offered them his covenant.
71 God made an everlasting covenant with Noah and with all living beings (cf. Gen 9:16). It will remain in force as long as the world lasts.
