After 40 years of studies, commissions and contradictions, the Vatican finally approved the spiritual devotion of the faithful at the Marian site at Medjugorje, in Bosnia-Herzegovina, in a document issued on Thursday.

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

Catholic worshipers who claim to have seen and spoken to the Virgin Mary at a Bosnian landmark received mixed messages from the Vatican on Thursday after the Church refused to say whether their visions were real — while still supporting worship at the site.
