St. Lawrence is thought to have been born on 26 December AD 225 in Valencia, or less probably, in Huesca, the town from which his parents came in the later region of Aragon that was then part of the Roman province of Hispania Tarraconensis. The martyrs St. Orentius (Modern Spanish: San Orencio) and St. Patientia (Modern Spanish: Santa Paciencia) are traditionally held to have been his parents.
He encountered the future Pope St. Sixtus II, who was of Greek origin and one of the most famous and highly esteemed teachers, in Caesaraugusta (today Zaragoza). Eventually, both left Spain for Rome. When Sixtus became the Pope in 257, he ordained St. Lawrence as a deacon, and though Lawrence was still young appointed him first among the seven deacons who served in the patriarchal church. He is therefore called “archdeacon of Rome”, a position of great trust that included the care of the treasury and riches of the Church and the distribution of alms to the indigent.
St. Cyprian, Bishop of Carthage, notes that Roman authorities had established a norm according to which all Christians who had been denounced must be executed and their goods confiscated by the Imperial treasury. At the beginning of August 258, the Emperor Valerian issued an edict that all bishops, priests, and deacons should immediately be put to death. Pope St. Sixtus II was captured on 6 August 258, at the cemetery of St. Callixtus while celebrating the liturgy and executed forthwith.
After the death of Sixtus, the prefect of Rome demanded that St. Lawrence turn over the riches of the Church. St. Ambrose is the earliest source for the narrative that St. Lawrence asked for three days to gather the wealth. He worked swiftly to distribute as much Church property to the indigent as possible, so as to prevent its being seized by the prefect. On the third day, at the head of a small delegation, he presented himself to the prefect, and when ordered to deliver the treasures of the Church he presented the indigent, the crippled, the blind, and the suffering, and declared that these were the true treasures of the Church. One account records him declaring to the prefect, “The Church is truly rich, far richer than your emperor.” This act of defiance led directly to his martyrdom and can be compared to the parallel Roman tale of the jewels of Cornelia.
On 10 August, St. Lawrence, the last of the seven deacons, and therefore, the ranking Church official, suffered a martyr’s death.
