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.

Roman Martyrology

Roman Martyrology - August 17

The Octave of St. Lawrence, martyr. — At Cracow, in Poland, St. Hyacinth, confessor, of the Order of Preachers, who slept in the Lord on the 16th of this month. — At Carthage, in Africa, the holy martyrs Liberatus, abbot, Boniface, deacon, Servus and Kusticus, subdeacons, Rogatus and Septimus, monks, and Maximus, a young child. In the persecution of the Vandals, under king Hunneric, they were subjected to various unheard-of torments for the confession of the Catholic faith and the defense of one baptism. Finally, being nailed to the wood wherewith they were to be burned, as the fire was always put out miraculously whenever kindled, they wrere struck with iron bars by order of the tyrant until their brains were dashed out. Thus they terminated the glorious series of their combats, and were crowned by our Lord. — At Caesarea, in Cappadocia, the birthday of St. Mamas, martyr, who, from childhood to old age, endured a long martyrdom, and at length ended it happily in the reign of Aurelian, under the governor Alexander. He has been highly praised by the holy fathers Basil and Gregory Nazianzen. — In Achaia, St. Myron, priest and martyr, who was beheaded at Cyzicum, after undergoing many torments, in the time of the emperor Decius and the governor Antipater. — At Nicomedia, the holy martyrs Straton, Philip and Eutychian, who were condemned to the beasts, but being uninjured by them, ended their martyrdom by fire. — At Teramo, St. Anastasius, bishop and confessor. — At Ptolemais, in Palestine, the holy martyrs Paul, and his sister Juliana, who suffered under Valerian.

Highlighted saint

St. Hyacinth

Confessor and preacher formed in the school of St. Dominic.

St. Hyacinth, a son of St. Dominic, carried Dominican preaching into the lands of the north and east, and is remembered in the Martyrology at Cracow in Poland.

His feast teaches apostolic movement governed by doctrine, prayer, and religious obedience. The preacher does not carry himself; he carries the faith received from Christ and His Church.

Virtue to practice

Apostolic perseverance.

Error to resist

The mission that prizes movement and influence more than received doctrine.

For the pilgrim in exile

Ask St. Hyacinth for Dominican steadiness. The faithful in exile need preaching that travels far without leaving truth behind.

Imitate today

  • Carry doctrine with humility.
  • Pray for Catholic preaching in hard places.
  • Let zeal be governed by obedience.

From Matins

The preacher who carried the rule into exile and mission.

Matins - Second Nocturn - St. Hyacinth, Confessor

Roman Breviary, Proper lessons for St. Hyacinth

Preaching and innocent life.

Doctrine taught

  • The Breviary presents St. Hyacinth as a Polish canon received by St. Dominic into the Order of Preachers and formed in exact observance of the rule.
  • His apostolate joined preaching, prayer, penance, chastity, humility, and missionary foundation, showing that reform of souls begins with the preacher's own conversion.
  • His reverent reception of the Sacraments at death and his final entrusting of his soul to God teach perseverance under the Church's prayer until the end.

For the pilgrim in exile

Let St. Hyacinth steady apostolic zeal. A soul sent into confused lands must carry doctrine, prayer, penance, and sacramental reverence together, or the mission loses its Catholic form.

Sources

  • The Roman Breviary, translated by John, Marquess of Bute, 1908, vol. III, Summer, Second Nocturn for St. Hyacinth, lessons iv-vi.
  • Bute 1908 is used here as an accessible pre-Pius X Breviary witness and is cited distinctly from the 1936-1937 Benziger / Burns Oates edition.

Breviary Witness

A preacher sent with Dominican steadiness.

Matins - St. Hyacinth

Breviary witness

  • The Breviary honors St. Hyacinth as a confessor of the Order of Preachers, a son of St. Dominic remembered for apostolic labor and religious fidelity.
  • His witness teaches that preaching must carry doctrine, prayer, and obedience together, especially when the road is long and the mission field wide.

For the pilgrim in exile

Pray for preaching that is mobile without becoming rootless. Catholic mission travels safely only when it remains obedient to received truth.

Meditation

The Church Made Public

Pentecost teaches that the Holy Ghost does not create private religious enthusiasm detached from doctrine, worship, and authority. He gathers, sends, teaches, and strengthens the visible Church. The remnant must therefore seek fire without disorder and zeal without novelty.

Prayer

The day should become prayer.

O Lord, make doctrine fruitful in habit. Let truth become patience, courage, purity, recollection, penance, charity, and perseverance.

Thought for the pilgrim

Virtue grows by repeated acts under grace.

Practice

The day should become obedience.

Choose one virtue for the day and practice it deliberately before evening.
