St. Sixtus II

Sixtus II (also spelled Xystus) served as Bishop of Rome for just under a year, from August 31, 257, until his death on August 6, 258. Very little is known of his early life or where he came from before his election, and even the exact circumstances of his appointment are sparsely documented. He appears to have been a Greek speaker or at least comfortable in Greek, which may explain the unusual policy he adopted early in his papacy regarding the treatment of the lapsed — Christians who had renounced their faith under persecution but now sought reconciliation with the Church.

His short pontificate was dominated by the crisis surrounding the apostates who had compromised their faith during the Decian persecution (250–251). A synod of African bishops had recently ruled that lapsi who had sacrificed to pagan gods could be restored to communion only after doing public penance, while those who had merely purchased certificates of sacrifice without actually performing the rites could be readmitted more easily. Sixtus II opposed this distinction, holding that no such leniency should be shown toward those who had actually performed the sacrifices, and he insisted on treating both categories alike — a stance that put him at odds with the influential Carthaginian bishop Cyprian and with Bishop Dionysius of Alexandria. He carried the day among Roman clergy, and his policy shaped the Roman response to the lapsed for some time afterward.

The persecution of Emperor Valerian, which began in 257 and intensified in 258, soon overshadowed these internal debates. Valerian's edicts required Christian clergy to perform pagan sacrifices under penalty of exile or death, and specifically targeted the Church's leadership and finances. Sixtus II, along with four of his seven deacons, was arrested on August 6, 258, while seated in a chair — the very seat of apostolic authority — celebrating the Eucharist in the cemetery of Praetextatus on the Appian Way. According to the account of the deacon Lawrence (who himself was martyred four days later), Sixtus reportedly comforted Lawrence by saying they would soon be together again.

Sixtus was beheaded on the spot, along with his four deacons — Januarius, Vincentius, Magnus, and Stephen — and several other members of the faithful present at the liturgy. He was buried in the nearby cemetery of Callixtus, in the papal crypt near his predecessor Cornelius. The Church remembers him as one of the earliest popes to be venerated specifically as a martyr, and his name was inserted into the Roman Canon of the Mass (the Eucharistic Prayer I), where it remains to this day — one of the very few saints besides the Blessed Virgin Mary and St. Joseph so commemorated in that ancient prayer.

Although details of his earlier career remain obscure, Sixtus II's legacy is secure. He is honored as a defender of orthodox discipline, a confessor of the faith under imperial persecution, and a pope who died at the altar he was serving. His commemoration in the Canon of the Mass and his traditional patronage of archbishops reflect the high regard the Church has long held for a pontiff whose brief tenure ended in bloodshed but whose witness endured.

The traditional claim that Sixtus II was the first pope martyred within the Vatican itself is difficult to verify with certainty; the location of his execution, the cemetery of Praetextatus, lay just outside the Aurelian Walls rather than within Vatican territory, and earlier popes may have suffered in or near the Vatican. The exact basis for the tradition is unclear, but his status as a papal martyr is firmly established in the historical record of the Roman Church.
