The fiery scholar who translated the Bible into Latin (the Vulgate), making Scripture accessible to the Western Church for over a millennium. After his baptism and Roman education, he retreated to the Syrian desert near Antioch for years of austere penance and Hebrew study before settling in Bethlehem, where he famously wrote that ignorance of Scripture is ignorance of Christ.
560 — 636 · Feast day: April 4
Born in Cartagena around 560 and educated by his brother St. Leander, Isidore succeeded Leander as Archbishop of Seville around 600 and led the Spanish Church for more than three decades. His Etymologiae — a twenty-volume encyclopedia drawing on hundreds of classical sources — became the standard reference work of the Middle Ages and preserved texts that would otherwise have been lost entirely.
c. 225 AD — 258 AD · Feast day: August 10
Lawrence served as Archdeacon of Rome under Pope Sixtus II, overseeing the Church's treasury and care of the poor. When the Roman prefect demanded he surrender the Church's wealth, he assembled the sick, the crippled, and the destitute and declared, 'These are the treasures of the Church.' Condemned to be roasted alive on a gridiron in 258 AD, he reportedly told his executioners, 'Turn me over — I am done on this side.'
