The Jubilee for the 50th anniversary of the International Diaconate Centre (IDC) was held in Rome and Assisi from 21 to 25 October, 2015. In all, 574 people, deacons, wives, priests and bishops from 35 countries around the world gathered for this celebration. Most of them stayed at Fraterna Domus on the outskirts of Rome.

There were various celebrations, reflections, prayers, testimonies and pilgrimages during the Jubilee. It is worth mentioning the Eucharists held at Fraterna Domus, in the Basilica of San Lorenzo and the Basilica di San Francesco in Assisi; and Cardinal Stella, prefect of the Congregation for the clergy in the Holy See, presided at the Eucharist celebrated at the beginning of the Jubilee. Due to the cancellation of the audience with Pope Francis, he sent a message of greeting, with the Apostolic Blessing, to the Jubilee participants
