The Miracle of Garabandal is a future event, revealed by the Blessed Virgin Mary first at Garabandal and then at Medjugorje (3rd secret). According to the visionaries of Garabandal, the Miracle consists of three things: (1) many people all over the world will be miraculously healed by God; (2) many unbelievers will be converted; (3) a Permanent Sign will be left at places of true private revelation throughout the world.
In my eschatology, I’ve concluded that the date for the Miracle is Thursday, 12 May 2016 (a few days before Pentecost).
At Garabandal, the visionary Conchita said that the Miracle will coincide with an event in the Church, one that has happened a few times in the past, but not since Conchita was born (she was born in 1949): “It is a singular event in the Church that happens very rarely, and has never happened in my lifetime…. It will happen on the same day as the Miracle, but not as a consequence of the Miracle, only coincidentally.” [Garabandal magazine, ‘The Warning and the Miracle,’ p. 28.]
Formerly, I said that this event would be the canonization of a Pope, specifically Pope John Paul II. But that cannot be the case, since his canonization and that of Pope John XIII are scheduled to take place in a few days (27 April 2014). A canonization of two Popes is a rare event in the Church, rarer than the canonization of a single Pope. I now think that the rare event which coincides with the Miracle is the canonization of two more Popes: Pope Pius XII and Pope Paul VI.
Venerable Pope Pius XII was ordained a Bishop on 13 May 1917. And on 11 May 1993, Venerable Pope Paul VI was declared Servant of God at the start of his process for beatification. So May 12th (2016) would be a fitting day for their canonizations.
