The Diocese of San Diego has two patron saints, San Diego and Our Lady of Refuge.
San Diego De Alcalá
The City of San Diego is named after St. Didacus, a 15th-century Franciscan brother from Alcalá, Spain, who worked in the infirmary of his convent and ministered to the poor. (“Didacus” is the Latinized form of “Diego.”)
When San Diego became its own diocese on July 11, 1936, it adopted as its principal patron the namesake of its most prominent church, Mission San Diego de Alcalá.
St. Didacus is traditionally depicted holding a soup pot – a symbol of his service to the poor – and the cross and three nails, which represent his devotion to the passion of Christ. The diocese’s crest highlights these elements.
The Feast of San Diego is celebrated on Nov. 7.
Our Lady of Refuge
The status of Our Lady of Refuge as a patron saint dates back to a time when all of Alta and Baja California comprised a single diocese. Under the title of Our Lady of Refuge, the Blessed Mother was proclaimed Patroness of Both Californias by the region’s first bishop on Jan. 4, 1843.
As the massive diocese divided into the many California dioceses we know today, each with its own patron saint, Our Lady of Refuge retained her role as co-patroness.
