Q. 1. What is the meaning of the word "Locutions?"
A. 1. A locution is a form of private revelation, similar to an apparition, but rather than being seen a locution is heard or received internally. As with all claims of private revelation it is important to be certain that a locution is authentic before any recognition or significance is determined.
The Catechism of the Catholic Church explains,
"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" (Catechism of the Catholic Church # 67)."
Wikipedia explains it as follows:
"An interior locution is a mystical concept used by various religions, including the Roman Catholic Church. In an interior locution, a person reportedly receives a set of (usually auditory) ideas, thoughts, or imaginations from an outside spiritual source. Interior locutions are most often reported during prayers. An interior locution is a form of private revelation, but is distinct from an apparition or religious vision because no supernatural entity is reported as present during the interior locution."
"In interior locutions, some people report quickly receiving large amounts of information. The determination of whether the locution was actually from another source or the person's mind itself is often the subject of controversy."
"In two examples, the Vatican biographies of both Saint Teresa of Avila and Mother Teresa of Calcutta refer to their interior locutions, although Mother Teresa often preferred to remain private about them. Some visions of Jesus and Mary are classified as visions by the Vatican rather than locutions, e.g. those of Faustina Kowalska or Margaret Mary Alacoque."
"Interior locutions sometimes lead to major new religious movements. For example, the interior locutions reported by the Roman Catholic priest Father Stefano Gobbi on May 8th 1972 at the shrine of Our Lady of Fatima led to the formation of the Marian Movement of Priests in October 1972 or the messages received through inner word by Jakob Lorber and Gottfried Mayerhofer, which formed the so-called New Revelation of Jesus Christ and led to a worldwide movement counting thousands of adherents who are not organized in an institutionalized religious form."
