Saint's Keep

Glossary

Converts drown in vocabulary. These are working definitions — what a term means, what it does not, and how you actually meet it in Catholic life. 45 entries and growing.

Devotion

  • Chaplet

    A set of prayers counted on beads, distinct from the full Rosary—e.g. the Divine Mercy Chaplet or chaplets to particular saints.

  • Consecration

    The act of setting a person or thing apart for God—supremely the Eucharistic consecration; also personal dedication to Christ or Our Lady.

  • Eucharistic Adoration

    Prayer before the Blessed Sacrament—reserved in the tabernacle or exposed in a monstrance—adoring Christ truly present.

  • Eucharistic devotion

    Prayer and rites centered on the Blessed Sacrament—adoration, Benediction, processions, and hymns of the Real Presence.

  • Marian

    Of or directed to the Blessed Virgin Mary—her feasts, antiphons, hymns, and the Church's filial devotion to the Mother of God.

  • Novena

    A nine-day pattern of prayer for a particular intention, modeled on the apostles' prayer between Ascension and Pentecost.

  • Relic

    The bodily remains of a saint, or an object closely connected with a saint or with Our Lord, honored by the Church with due veneration.

  • Sacramental

    A sacred sign instituted by the Church—holy water, medals, scapulars, blessings—that disposes the soul for grace; not one of the seven Sacraments.

  • Scapular

    A sacramental of two small cloth panels worn over the shoulders, signifying consecration and enrollment in a religious family or devotion.

Doctrine

  • Acedia

    Spiritual listlessness or disgust with the good of prayer — not mere laziness; classically linked to the noonday demon of Psalm 90/91.

  • Indulgence

    A remission before God of temporal punishment due to sins already forgiven, granted by the Church from the treasury of merits.

  • Latria, Dulia, and Hyperdulia

    Classical terms: latria is worship of God alone; dulia is veneration of saints; hyperdulia is the unique veneration due to Mary.

  • Plenary vs. Partial Indulgence

    A plenary indulgence remits all temporal punishment; a partial remits part. Both require the Church's grant and the proper dispositions.

  • Private Revelation

    Revelations given to individuals after the close of public revelation—never equal to Scripture or dogma, even when Church-approved.

  • Sacrament vs. Sacramental

    Sacraments are seven signs instituted by Christ that confer grace; sacramentals are Church-instituted signs that dispose the soul for grace.

  • Veneration vs. Worship

    Worship (latria) is due to God alone; veneration (dulia) honors saints and angels. Confusing them is the charge—and the Catholic answer is distinction.

Hierarchy

  • Doctor of the Church

    A saint whose teaching the Church has formally recognized as outstanding in doctrine and holiness of life.

  • Magisterium

    The Church's teaching authority, exercised by the Pope and bishops in communion with him, guarding and handing on the deposit of faith.

History

  • Apparition

    A reported supernatural appearance of Christ, Our Lady, or a saint. Even when approved, it belongs to private revelation.

Canon Law

  • Imprimatur

    An official declaration by a bishop that a book is free of doctrinal or moral error and may be printed—literally, "let it be printed."

  • Nihil Obstat

    A censor's judgment that a manuscript contains nothing opposed to Catholic faith or morals—literally, "nothing stands in the way."

Liturgy

  • Advent

    The four-week season preparing for Christmas—watching for Christ's coming in history, in grace, and at the end of time.

  • Antiphon

    A short scriptural or liturgical text sung or said before and after a psalm, canticle, or as a refrain in the Mass and Office.

  • Benediction of the Blessed Sacrament

    A rite of Eucharistic devotion: the Host exposed, hymns sung, and the priest blessing the people with the Blessed Sacrament.

  • Christmas

    The feast of the Nativity and its season—God born in the flesh, prolonged through the octave and Christmastide.

  • Compline

    Night Prayer—the final hour of the Divine Office before sleep, classically including the Nunc Dimittis and a Marian antiphon.

  • Divine Office

    The Church's daily liturgy of psalms, hymns, and readings sanctifying the hours—also called the Liturgy of the Hours.

  • Easter

    The feast of the Resurrection and its fifty-day season—Christ risen, through the octave to Pentecost.

  • Ferial

    A weekday in the liturgical calendar that is not a feast—kept with ferial (weekday) Mass texts rather than a saint's proper.

  • Graduale Romanum

    The official book of Mass chants for the Roman Rite — graduals, tracts, alleluias, and related propers as used in the Gregorian tradition.

  • Lauds

    Morning Prayer of the Divine Office—psalms of praise at daybreak, classically including the Benedictus.

  • Lent

    The forty-day penitential season before Easter—fasting, prayer, and almsgiving in preparation for the Passion and Resurrection.

  • Liturgy of the Hours

    The postconciliar name for the Divine Office—the Church's official daily prayer of psalms and readings across the hours.

  • Mass

    The liturgical book containing the texts of the Mass—the priest's altar missal, or a hand missal for the faithful to follow.

  • Mode (Gregorian)

  • Octave

    An eight-day liturgical celebration of a great feast, prolonging its joy and mystery through the following week.

  • Ordinary Time

    The green seasons of the liturgical year outside Advent, Christmas, Lent, and Easter—ordered growth in the mystery of Christ.

  • Passiontide

    The final stretch of Lent focused on the Passion—traditionally the two weeks before Easter, culminating in Holy Week.

  • Pentecost

    The feast of the Holy Spirit's descent—and the close of Eastertide—fifty days after the Resurrection.

  • Propers

    The variable prayers and chants of the Mass or Office assigned to a given day—introit, collect, readings, and the like.

  • Requiem

    A Mass offered for the dead—praying that God grant them rest, mercy, and the light of His face.

  • Tract

    A Gregorian chant sung after the Gradual in penitential Masses when the Alleluia is omitted — often long and meditative (e.g. Qui habitat).

  • Vespers
