VATICAN CITY (AP) — Pope Francis today cleared Pope John Paul II for sainthood, approving a miracle attributed to his intercession and setting up a remarkable dual canonization along with another beloved pope, John XXIII.

In a major demonstration of his papal authority, Francis decided to make John XXIII a saint even though the Vatican hasn’t confirmed a second miracle attributed to his intercession. The Vatican said Francis had the power to “dispense” with the normal saint-making procedures to canonize him on his own merit, without a miracle.

The ceremonies are expected before the end of the year. The date of Dec. 8 has been floated as one possibility, given it’s the feast of the Immaculate Conception, a major feast day for the church. Polish media continued to report that October was likely, to mark the anniversary of John Paul’s election, but Vatican officials have said that’s too soon to organize such a massive event.
