On January 18, 1987, a press release dated January 9, signed by Cardinal Franjo Kuharic, president of the Yugoslavian Conference of Bishops and by Bishop Zanic of Mostar, made the front page of "Glas Koncila" with the announcement of the formation of a new Commission of inquiry on Medjugorje [it then appeared in “L'Osservatore Romano” on February 14, 1987 -- dk]. Here is the text:
In accordance with the canonical regulations which treat the matters of discernment of alleged apparitions and private revelations, the Diocesan Commission formed for that purpose by the Bishop of Mostar, the local Ordinary, investigated the events of Medjugorje.
During the inquiry these events under investigation have appeared to go much beyond the limits of the diocese. Therefore, on the basis of the said regulations, it became fitting to continue the work at the level of the Bishops' Conference, and thus to form a new Commission for that purpose.
The Congregation for the Doctrine of the Faith has been informed about it. It has expressed its recognition of the Diocesan Commission's work done under the responsibility of the local Ordinary, and it urged that that work be continued at the level of the National Conference of Bishops.
Thus the Bishops Conference of Yugoslavia will form a Commission to continue the investigation of Medjugorje's events. While waiting for the results of the Commission's work and the Church's verdict, let the Pastors and the faithful honor the practice of the usual prudence in such circumstances. For that reason, it is not permitted to organize either pilgrimages or other religious manifestations based on an alleged supernatural character attributed to Medjugorje's events. Marian devotion, legitimate and recommended by the Church, must be in accordance with the directives of the Magisterium, and especially the apostolic encyclical Marialis Cultus February 2, 1974 (cf. AAS, 66, 1974, p. 113-168).
