Sacred Calendar

The Roman year ordered for memory, penance, feasts, saints, and the daily pilgrimage of the faithful.

Calendar standard

Pre-1955 Roman usage

The calendar follows the universal Roman year under the rubrics of Pope St. Pius X, with the Roman Martyrology preserved as a distinct daily witness.

The day is presented for prayer, recollection, study, and perseverance in the City.

Daily observance

Roman Martyrology

Roman Martyrology - December 29

At Canterbury, in England, the birthday of St. Thomas, bishop and martyr, who, for the defence of justice and ecclesiastical immunities, was struck with the sword in his own basilica by a faction of impious men, and thus went to Christ. — At Jerusalem, holy David, king and prophet. — At Aries, the birthday of St. Trophimus, mentioned by St. Paul in his epistle to Timothy. Being consecrated bishop by that apostle, he was the first sent to preach the gospel of Christ in that city. From his preaching as from a fountain, according to the expression of pope St. Zosimus, all Gaul received the waters of salvation. — At Rome, the holy martyrs Callistus, Felix and Boniface. — In Africa, the holy martyrs Dominic, Victor, Primian, Lybosus, Saturninus, Crescentius, Secundus and Honoratus. — At Vienne, in France, St. Crescens, disciple of the blessed apostle Paul, and first bishop of that city. — At Constantinople, St. Marcellus, abbot. — In Normandy, St. Ebrnlphus, abbot and confessor, in the time of king Childebert.

Highlighted saint

St. Thomas of Canterbury

Bishop and martyr slain in his own basilica.

The Martyrology honors St. Thomas, bishop and martyr of Canterbury, who for the defence of justice and ecclesiastical immunities was struck with the sword in his own basilica by impious men.

His feast teaches that the liberties of the Church are not privileges of pride, but protections for divine worship, sacred office, and the salvation of souls.

St. Thomas did not die for a private quarrel. He died because civil power wanted sacred authority to bend beneath it. The Church may suffer from bad churchmen, but her divine rights do not become property of the state.

Virtue to practice

Courage for ecclesiastical liberty.

Error to resist

The Erastian habit that treats the Church as subject to the convenience of the state.

For the pilgrim in exile

Ask St. Thomas of Canterbury for courage where sacred things are pressured by power. The altar does not belong to the state, and conscience must not be trained to think it does.

Imitate today

  • Defend the Church's freedom from unjust power.
  • Pray for bishops under political pressure.
  • Choose justice over safety.

Meditation

The Coming of the King

The mystery of the coming of Christ teaches the pilgrim to wait without surrender, to recognize divine humility, and to adore the King where He truly appears. Sacred time trains hope, but hope must remain disciplined by doctrine and worship.

Prayer

The day should become prayer.

O Lord, do not permit me to admire truth without submitting to it. Give me the courage to obey what Thou hast already made known.

Thought for the pilgrim

Truth becomes fruitful when it is obeyed.

Practice

The day should become obedience.

Choose one known duty and obey it without delay or complaint.
