 The cause for La Pira's beatification commenced in Florence in a diocesan phase that Cardinal Silvano Piovanelli inaugurated on 9 January 1986 and which Cardinal Ennio Antonelli closed two decades later on 4 April 2005.This diocesan process was charged with hearing witness testimonies - which included Hassan II of Morocco - and collecting documents relating to La Pira's life and works.This also included his published and unpublished writings which required theological approval in order to see if there was a potential contravention of doctrine in them.
