Beth Racine had just come out of church after confession in Medjugorje and was leaning against a wall when something caught her eye. A disc covered the sun. She saw swirling colors to the sides — red on one side and white on the other — that made her think of the image of Divine Mercy.

More than 40 million pilgrims from around the world have flocked to the small village named Medjugorje since 1981.

In June 1981, six children aged 10 to 16 claimed that the Virgin Mary appeared to them on a hilltop near the town.

The issue of Marian apparitions in Medjugorje stirs considerable controversy among the faithful and those outside the Church. Some are convinced of the events' authenticity, while others harbor significant doubts.

Pope Francis has approved a Catholic spiritual devotion centred in Medjugorje, a town in Bosnia that has been steeped in controversy over whether the Virgin Mary appears to local people, the Vatican said on Thursday.

The Holy See has authorized the faithful to “prudently adhere” to the presumed messages of the Virgin at Medjugorje. From now on, these messages will be reviewed by a papal delegate before publication.

The Vatican on Thursday gave that “nihil obstat” to Medjugorje. The local bishop issued the decree authorizing devotion there, and it is now possible that a sanctuary could be built, said the head of the doctrine office, Cardinal Víctor Manuel Fernández.

The Vatican issued a long-awaited note on the alleged apparitions at Medjugorje, in Bosnia and Herzegovina. It did not say the apparitions were authentic but acknowledged spiritual fruit.

Pope Francis has expressed some doubts on the messages, commenting in 2013 on the Virgin Mary’s particularly chatty nature at Medjugorje.
