Deepertruth: Journey With Mary as we return back to her reported visions at Ohio

Determining the veracity of an apparition falls to the local bishop, and the Vatican's doctrinal congregation established the norms to guide the process.

Granting approval is never brief, with some cases taking hundreds of years. Visionaries and witnesses must be questioned and the fruits of the apparitions, such as conversions, miracles and healings, must be examined.

According to the norms, the local bishop should set up a commission of experts, including theologians, canonists, psychologists and doctors, to help him determine the facts, the mental, moral and spiritual wholesomeness and seriousness of the visionary, and whether the message and testimony are free from theological and doctrinal error.

A bishop can come to one of three conclusions: He can determine the apparition to be true and worthy of belief; he can say it is not true, which leaves open the possibility for an appeal; or he can say that at the moment he doesn't know and needs more help.

The Reported occcurances i Barberton Ohio in the early 1990's is still open and being investigated.  They are yet to be endorced by the Church.
