In 2015, Pope Francis called an Extraordinary Jubilee Year of Mercy. Typically, in the past, pilgrims were required to travel to Rome and pass through the four major basilicas, but for the first time in the Judea-Christian tradition, the pope allowed there to be holy doors throughout every diocese in the world. Even extending the concept as far as enabling jail cell doors to be utilized as thresholds for prisoners and for infirmary doors to used for those who were sick.
In addition to the Roman Holy Doors, the PrayerARK was offered up throughout the US, Portugal, Spain, France, and Italy.
