On Friday, May 5, 2023, at the Vatican’s Dicastery for the Causes of Saints, the ceremony for the opening of the boxes of the Acts of the diocesan process of the Cause of beatification and canonization of Marta Obregón, by way of martyrdom, took place. It was a simple but solemn, moving and emotional ceremony. This step marks the resumption of the in-depth research carried out in this second phase.
