3) Private revelations received by individuals after the time of the Apostles may, in some cases, change the teachings of the Church.
The answer is: False
“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. . . . 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.’” Catechism of the Catholic Church, paragraph 67
