Saint Isidore of Seville

Saint’s Life Story

Saintly Siblings

Isidore was born around 560 in Cartagena, Spain to his pious parents, Severianus and Theodora. He had a younger brother, Saint Fulgentius, an older brother Saint Leander, and a sister Saint Florentina.   Isidore was educated under the supervision of his older brother Leander. 

Bishop of Seville

Isidore succeeded him as Bishop of Seville around 600. Isidore became noted as one of the most learned men of his times, continuing Leander’s work of converting the Arian Visigoths. He presided over several important councils, including that of Seville in 619 and Toledo in 633. 


Isidore was greatly interested in education and he founded schools in each diocese similar to our present-day seminaries. He broadened the curriculum to include liberal arts, medicine, and law as well as the conventional subjects. Isidore compiled the Etymologies, an encyclopedia of the knowledge of his times. He was a voluminous writer. Isidore wrote treatises on theology, astronomy, and geography, histories (where his history of the Goths is the principal information about them), and biographies.

His Death

Isidore was known for his austerities and his charities and is considered the last of the ancient Christian philosophers.  Isidore was well versed in the Latin, Greek, and Hebrew languages. He governed his church about 37 years, continuing his assiduous labors up to an advanced old age. On April 4, 636, Isidore died in Seville, Spain. Isidore was declared a Doctor of the Church by Pope Benedict XIV in 1722.

The strength of temptation usually lies in the fact that its object is something flattering to our pride, soothing to our sloth, or in some way attractive to the baser passions. Saint Isidore teaches us to listen neither to the promptings of nature nor the plausible advice of friends, when they contradict the voice of God.

What do you do when friend’s advice contradicts the voice of God? My recommendation is to hand yourself over to prayer.

Saint Isidore, you used your education and knowledge to great effect to evangelize people. Help all who seek your intercession to unite their learning with zeal for the good of the Church and the many peoples it serves.

Saint Isidore of Seville, pray for us. Amen.
