I think that the Church’s teaching on Medjugorje is very clear. The bishops of the countries of the former Yugoslavia took a clear position in 1991. This is still valid and has been confirmed by the Vatican twice. There are three important points in this statement. First, that it is not confirmed that the events are of supernatural origin. That means it is neither confirmed nor denied. The Church left it open.
The second point is that as the so-called apparition question and message question has not been decided it is not permissible to make official pilgrimages to Medjugorje. So, for example, I cannot organize a formal diocesan pilgrimage to Medjugorje as we can to Rome or Fatima or Lourdes.
The third point, however, is that the people who choose to go to Medjugorje on their own are entitled to spiritual care. So, we priests or bishops are invited to provide spiritual company to pilgrims. That’s what my predecessors in Vienna did from the very beginning regarding Medjugorje, and that’s what I continue to do. I think these three points are sufficient for a good understanding of how to approach Medjugorje. The most important for me are the overwhelming good spiritual fruits of Medjugorje (Read FULL interview at OSV)
