The diocesan process for the cause for canonisation of French YCW founder-chaplain, Fr Georges Guérin, concluded at a ceremony in Paris on 16 May 2025.
Vicar-general Mgr Michel Guéguen presided at the event which took place at the office of the Workers’ Catholic Action (ACO) movement.
Born on 24 October, 1891 in Grandménil, commune of Écrouves (Meurthe-et-Moselle), Fr Guérin died on March 15, 1972 in Paris.
An apprentice metal tester then an office worker, he was ordained a priest of the diocese of Paris in 1925 and was appointed vicar at St Vincent de Paul parish in Clichy, an inner suburb.
Appointed as chaplain to the new movement in 1927, he remained in this post until 1950.
Georges Guérin is now recognised as a “servant of God.”
The process now moves to Rome, where another investigation will rule on the heroic nature of his virtues and eventual recognition as “venerable.”
