The following exerpts are from a longer article about the apparitions regarding Our Lady of Good Success in Quito, Equador in the early 17th century. Although approved by the Church, the revelations have been hidden until now. Our Lady said that this devotion would become known at a time when the Catholic Church would be in a period of grave crisis when seemingly all would be lost.
“Question: I have never heard of the prophecies of Our Lady of Good Success. Is this a new apparition? Has it been approved by the Church?
Answer: This is not a new apparition. It took place in the early 17th century. The revelations of Our Lady of Good Success and devotion to Her miraculous Statue have been approved by the Catholic Church since the beginning. It was the 9th Bishop of Quito, Salvador de Ribera, who attested in official documents to the miraculous completion of the Statue by St. Francis of Assisi and the three Archangels – St. Michael, St. Gabriel and St. Raphael – and presided over the anointing of the solemn consecration of the Statue in the Church of the Royal Convent of the Immaculate Conception on February 2, 1611. The devotion and apparitions were also authorized and promoted by the next Bishop of Quito, Pedro de Oviedo, who governed the Diocese from 1630 to 1646. Thus this devotion has enjoyed the support and approval of the Church since its very beginning.”
“Question: How is the devotion spreading today?
Answer: Today the fame of this apparition is extending far beyond Quito. Our Lady of Good Success told Mother Mariana that She wanted to be known and loved throughout the world, and that the devotion would begin to spread only in the 20th century. This is, in fact, what has happened. She reserved this devotion for these times because the Church would be so embattled and suffering that only the divine power and love of the Blessed Virgin would sustain the faithful.”
