Sts. Marcellinus and Peter

Sts. Marcellinus and Peter were Roman clergy secretly executed during Diocletian’s persecution and honored among the martyrs named in the Roman Canon.

The story

Marcellinus and Peter were members of the Roman clergy during the persecution associated with Emperor Diocletian. Ancient sources identify Marcellinus as a priest and Peter as an exorcist, which was then a recognized minor order of the Church. Little is securely known about their earlier lives or ministries. Their deaths are generally dated around 304, when Christians in Rome faced imprisonment, confiscation, torture, and execution for refusing sacrifice to the Roman gods.

The most important early testimony comes from Pope St. Damasus I, who governed the Church from 366 to 384. In an inscription placed at their tomb, Damasus said that, when he was a boy, he had heard the account from the executioner himself. According to this testimony, Marcellinus and Peter were taken to an isolated place and ordered to clear the ground and dig their own graves. They were then beheaded in secrecy so that other Christians would not know where they had died.

Their burial place nevertheless became known. A later account names a devout woman called Lucilla as the person who recovered their bodies, but this detail belongs to a tradition whose historical certainty is limited. The martyrs were buried on the Via Labicana at the cemetery known as ad duas lauros, near modern Tor Pignattara. Their commemoration on June 2 is recorded in the fourth-century Roman calendar known as the Depositio Martyrum, demonstrating the antiquity of their cult.

Emperor Constantine later built a basilica near their burial place, and his mother, St. Helena, was buried in a mausoleum beside it. Pope Damasus honored the martyrs with his inscription, preserving the memory of their hidden execution. Their names were eventually included in the Roman Canon, now also called Eucharistic Prayer I, alongside other early martyrs of Rome. The General Roman Calendar keeps their optional memorial on June 2. Although many personal details have been lost, their names remain spoken at the altar as witnesses who preferred death to denying Christ.

What Marcellinus teaches

Sts. Marcellinus and Peter teach that no act of fidelity is hidden from God, even when earthly authorities try to erase it. Their honorable burial also recalls the Christian duty to respect the bodies of the dead. See CCC 2300 and Revelation 2:10.
