[1] The 2016 Jubilee was first announced by Pope Francis during a homily at Mass on 13 March 2015, at which he said that the church must always keep its doors open so no one is excluded from God's mercy.

[1] The bull is the fundamental document for the Holy Year that outlines the overall spirit and intentions for the Jubilee, as well as the spiritual fruits that are hoped for.

[2] It then quotes from Dei verbum, the dogmatic constitution on divine revelation issued by the Second Vatican Council: "To see Jesus is to see His Father (John 14:9)".

On December 8, 2015, the Pope formally inaugurated the Jubilee with the opening of the Holy Door at St. Peter's Basilica in Rome.

Pope Francis later opened the Holy Door at Basilica di Santa Maria Maggiore and at the Caritas center near Rome's central train station.
