True! It is important to first state that the priests serving in Medjugorje are appointed by the bishop and that they are all under obedience. With that said, the replacement for Bishop Zanic, who was in power at the time the apparitions began, was Bishop Ratko Peric.
Bishop Ratko worked closely with Bishop Zanic for years, and it was no surprise that he held, and still holds, the same negative opinion of Medjugorje. In a conversation that Fr. John Chisholm had with Bishop Ratko Peric, Fr. John asked the bishop if he believed in Lourdes. The bishop slammed his fist on the table and yelled "NO". Fr. John asked the bishop if he believed in Fatima, and received the same answer. With this information, it would seem unlikely that the bishop would believe in Our Lady's apparitions in his own diocese. The Bishop is reported to have never investigated Medjugorje, never spoken with or interviewed the visionaries, and visits Medjugorje only rarely for Confirmations and official functions. But with this said, the important issue is that Bishop Ratko Peric does not have authority over the Churchs decision on Medjugorje. In a recent interview the bishop acknowledged this fact when he said: "while recognizing the Holy Father's right to give a final decision" on the validity of the reported apparitions... This responsibility still rests with the commission of Bishops. The local Bishop's negative comments about Medjugorje were addressed directly in 1998 by the Holy See in a letter to his Excellency Mons. Gilbert Aubry, Bishop of Saint-Denis de la Reunion. The letter states that Bishop Peric's position on Medjugorje is his personal opinion, which he is entitled to as local Bishop, but remains his personal opinion.
