Information

St. Isidore was the bishop of Seville in Central Spain. He had two brothers that are saints: Leander and Fulgentius, and a sister who is a saint, Florentina. St. Isidore is most noted for his conversion of the Visigoths from Arianism to Catholicism. He wrote the "History of the Goths" and the "Book of Etymologies". St. Isidore died in 636 and was declared Doctor of the Church in 1722.

A Doctor of the Church, (from the Latin docere, to teach), is a saint from whose writings the whole Church is held to have derived great advantage and to whom "eminent learning" and "great sanctity" have been attributed. The honour is always bestowed posthumously.
