This is a great opportunity to send out the friendly reminder that Bl. John Paul II's canonization is not yet approved. One Catholic media figure used Facebook and Twitter to announce a definite Oct. 20, 2013 date, but there is no documentation about this.
Let's just review what has occurred, with the help of Vatican journalist Andrea Tornielli (emphasis mine):
It all happened in great secrecy, with maximum confidentiality. In January, the postulator of the cause, Mgr. Slawomir Oder, submitted a presumed miraculous healing to the Vatican Congregation for the Saints for a preliminary opinion. As it is known, after the approval of a miracle for the proclamation of a blessed, the canonical procedures include the recognition of a second miracle that must have occurred after the beatification ceremony.
Two doctors of the Vatican council had previously examined this new case, and both gave a favourable opinion. The dossier with the medical records and the testimonies was then officially presented to the Congregation, which immediately included the examination in its agenda. In the past few days it was discussed by a committee of seven doctors, the council (presided over by Dr. Patrick Polisca, Pope John Paul II's cardiologist), Pope Benedict XVI's personal physicians and now Pope Francis's. The medical council also gave a favourable opinion, the first official go-ahead by the Vatican, by defining as inexplicable the healing attributed to the intercession of the blessed Karol Wojtyla.
This is the overcoming of the first fundamental hurdle, given that the alleged miracle must now be approved by theologians and then by the cardinals and bishops of the Congregation, before being subjected to the Pope for the definitive "yes". In any case, the approval of the council is considered the most important step; in fact, neither the theologians nor the cardinals are involved in the clinical evaluations concerning the case.
So, the cause is still underway, but not yet approved, and certainly not on the calendar. Could it be on October 20, 2013? Certainly. But let's not forget that right now it's a could, not a will. In other words, hold off on the plane tickets for now. We might have to wait awhile. In fact, wouldn't it be beautiful if the canonization plans were officially announced at World Youth Day this July?
