Roman Martyrology

Roman Martyrology - May 12

At Rome, on the Ardeatine road, the holy martyrs Nereus and Achilleus, brothers, who first underwent a long exile for Christ in the island of Pontia with Flavia Domitilla, whose chamberlains they were. Afterwards they endured a most severe scourging. Finally, as the ex-consul Minutius Rufus endeavored by using the rack and fire to force them to offer sacrifices, they said, that having been baptized by the blessed Apostle Peter, they could by no means sacrifice to idols. They were beheaded, and their sacred relics, with those of Flavia Domitilla, were, by order of pope Clement VIII., solemnly transferred the day before this, from the sacristy of St. Adrian to their ancient church now repaired, in which they were formerly preserved. — In the same place, on the Aurelian road, the holy martyr Pancratius, who, at fourteen years of age, endured martyrdom by decapitation under Diocletian. — Also, at Rome, St. Denis, uncle of the same blessed Pancratius. — In Sicily, St. Philip Argyrio, who was sent to that island by the Roman Pontiff, and converted to Christ a great portion of it. His sanctity is particularly manifested by the deliverance of possessed persons. — At Salamis, in Cyprus, St. Epiphanius, a bishop of great erudition and profound knowledge of the holy Scriptures. He was also admirable for the sanctity of his life, his zeal for the Catholic faith, his charity to the poor, and the gift of miracles. — At Constantinople, St. Germanus, a bishop distinguished by virtues and learning, who with great courage reprehended Leo the Isaurian for promulgating an edict against holy images. — At Treves, St. Modoaldus, bishop. — At Calzada, St. Dominic, confessor.

Highlighted saint

Ss. Nereus, Achilleus, Domitilla, and Pancras

Roman martyrs who refused idols and bore exile, youth, and blood.

Ss. Nereus and Achilleus, brothers and chamberlains of Flavia Domitilla, first endured exile for Christ, then scourging, and finally beheading after refusing to sacrifice to idols.

St. Pancras, only fourteen years old, endured martyrdom by decapitation under Diocletian, showing that youth does not lessen the call to confess Christ.

Virtue to practice

Youthful and steadfast martyr courage.

Error to resist

The compromise that says age, office, or weariness excuses public betrayal.

For the pilgrim in exile

Ask these Roman martyrs for clean refusal. The soul baptized into Christ cannot bow to idols, even when the world calls refusal unreasonable.

Imitate today

  • Refuse the idols nearest your life.
  • Teach the young courage and purity.
  • Persevere when exile becomes wearisome.

Breviary Witness

The Roman martyrs who would not sacrifice to idols.

Matins - Ss. Nereus, Achilleus, Domitilla, and Pancras, Martyrs

Breviary witness

  • The Breviary honors these Roman martyrs: Nereus and Achilleus after exile and scourging, Domitilla in faithful confession, and Pancras in youthful martyrdom.
  • Their witness teaches that baptism forbids idolatry, and that age, rank, exile, and suffering do not excuse betrayal.

For the pilgrim in exile

Refuse the idols of the age plainly. The martyrs teach that clean refusal can be more eloquent than many words.

Gospel of the day

Be glad in that day and rejoice.

Ss. Nereus, Achilleus, Domitilla, and Pancras, Martyrs - Luke 6:17-23

Be glad in that day and rejoice; for behold, your reward is great in heaven.

What Our Lord teaches

  • The martyrs prefer heavenly reward to safety bought by idolatry.
  • These Roman witnesses teach that baptism requires clean refusal when the world demands sacrifice to false gods.

Virtue to practice

Refuse idols with simplicity, whether in youth, exile, service, or suffering.

Error to resist

The compromise that excuses public betrayal because the cost of refusal is high.

For the pilgrim in exile

Ask the Roman martyrs for a clean no. A baptized soul cannot make peace with idols and remain whole.

  • Traditional Roman Gospel from the common of martyrs.

Meditation

Victory Seen in Christ

The day lifts the pilgrim above mere survival. The Church suffers, but she suffers under the Lord who is risen, ascended, glorified, and victorious in His saints. Triumph is not a mood. It is the promised end toward which perseverance is ordered.

Prayer

The day should become prayer.

O Lord, pardon my faults, raise my heart from discouragement, and teach me to begin again under Thy mercy.

Thought for the pilgrim

The pilgrim is formed by returning to God again and again.

Practice

The day should become obedience.

Make a brief examination of conscience before sleep and end the day with an act of contrition.
