What is the Official Status of Medjugorje (as of this post)
The Church's current position is that of the 1991 Zadar Declaration in which it was stated (my note in red, bracketed):
On the bas[is] of studies made so far, it cannot be affirmed Non constat de supernaturalitate (not established as supernatural). that these matters concern supernatural apparitions or revelations.
There are three possible decisions the Church can make. This is not a wholly negative judgment, nor is it a positive judgment. It leaves open the possibility for further study.
The 1991 Zadar Declaration has been cited numerous times in Vatican documents with regards to the current status, such as on those pertaining to pilgrimages and Medjugorje. It was also referred to in 2006 by Vinko Cardinal Puljic of the now Bosnia-Herzegovina Bishops Conference (BiH) upon announcing a new commission was apparently being established.
In that 2006 comment by Cardinal Puljic, he says the new commission will study the original decision of the 1991 Commission, as well as the issue of pilgrimages.
