My friends knob has an apparition of the virgin mary on it, would the vatican be interested?
If he will investigate about that apparition, will vaste a lot of time and possibly also money. The faith is the Way given by God; there may be apparitions, but be aware that it is really difficult to ascertain their source. You could read the “Ascent of Mt. Carmel” by St. John of the Cross; he reports valuable teachings about how to handle apparitions and mystcal christian life. A suggestion; just ignore that apparition. Try to have a better Christian life, and all will go OK. If it’s a true apparition, will also have its effects. Otherwise, he will not waste time and efforts. PS. He can contact his confessor or his bishop. But later has to obey them.
