In February 1925, the Cardinal Secretary of State Pietro Gasparri summoned him to the Vatican and informed him of Pope Pius XI's decision to appoint him as the Apostolic Visitor to Bulgaria (1925–35). On 3 March, Pius XI also named him for consecration as titular archbishop of Areopolis, Jordan. Roncalli was initially reluctant about a mission to Bulgaria, but he would soon relent. His nomination as apostolic visitor was made official on 19 March. Roncalli was consecrated by Giovanni Tacci Porcelli in the church of San Carlo alla Corso in Rome. After he was consecrated, he introduced his family to Pope Pius XI. He chose as his episcopal motto Obedientia et Pax ("Obedience and Peace"), which became his guiding motto. While he was in Bulgaria, an earthquake struck in a town not too far from where he was. Unaffected, he wrote to his sisters Ancilla and Maria and told them both that he was fine.
When was he the Apostolic Visitor to Bulgaria?
****
