Shortly the day will come on which will be commemorated the 150th anniversary of the pious departure to Heaven of St John Mary Vianney, the Curé d‘Ars. This Saint was a wonderful model here on earth of a true Pastor at the service of Christ‘s flock.
Since his example is used to encourage the faithful, and especially priests, to imitate his virtues, the Supreme Pontiff Benedict XVI has established that for this occasion a special Year for Priests will be celebrated, from 19 June 2009 to 19 June 2010, in which all priests may be increasingly strengthened in fidelity to Christ with devout meditation, spiritual exercises and other appropriate actions.
This holy period will begin with the Solemnity of the Sacred Heart of Jesus, a day of priestly sanctification on which the Supreme Pontiff will celebrate Vespers in the presence of the holy relics of St John Mary Vianney, brought to Rome by the Bishop of Belley-Ars, France.
