Giacomo Radini-Tedeschi, the new Bishop of Bergamo, appointed Roncalli as his secretary. Roncalli worked for Radini-Tedeschi until the bishop's death on 22 August 1914, two days after the death of Pope Pius X. Radini-Tedeschi's last words to Roncalli were "Angelo, pray for peace". The death of Radini-Tedeschi had a deep effect on Roncalli. During this period Roncalli was also a lecturer in the diocesan seminary in Bergamo. During World War I, Roncalli was drafted into the Royal Italian Army as a sergeant, serving in the medical corps as a stretcher-bearer and as a chaplain. After being discharged from the army in early 1919, he was named spiritual director of the seminary. On 7 May 1921, Roncalli was appointed a Domestic Prelate of His Holiness, which gave him the title of Monsignor. On 6 November, he travelled to Rome where he was scheduled to meet the Pope. After their meeting, Pope Benedict XV appointed him as the Italian president of the Society for the Propagation of the Faith. Roncalli would recall Benedict XV as being the most sympathetic of the popes he had met.

On 3 March, Pius XI also appointed him titular archbishop of Areopolis, Jordan. Roncalli was initially reluctant about a mission to Bulgaria, but he soon relented. His nomination as apostolic visitor was made official on 19 March. Roncalli was consecrated a bishop by Giovanni Tacci Porcelli in the church of San Carlo al Corso in Rome. On 30 November 1934, he was appointed Apostolic Delegate to Turkey and Greece and titular archbishop of Mesembria, Bulgaria. He became known in Turkey's predominantly Muslim society as "the Turcophile Pope". Roncalli took up this post in 1935 and used his office to help the Jewish underground in saving thousands of refugees in Europe, leading some to consider him to be a Righteous Gentile (see Pope John XXIII and Judaism). In October 1935, he led Bulgarian pilgrims to Rome and introduced them to Pope Pius XI on 14 October. In February 1939, he received news from his sisters that his mother was dying. On 10 February 1939, Pope Pius XI died. Roncalli was unable to see his mother for the end as the death of a pontiff meant
