The Catholic Church

The Catholic Church confesses the Christian doctrine of one God in three Persons (Father, Son, Holy Spirit), articulated principally in the Nicene Creed (325 AD, revised 381 AD). The Nicene Creed is recited at every Sunday Mass; the shorter Apostles' Creed is used at the baptismal rite. The Trinitarian formula (Father, Son, Holy Spirit) marks the sign of the cross, the baptismal formula, and the principal blessings.

Christ is true God and true man, the second person of the Trinity become incarnate. The doctrine of the hypostatic union (one person, two natures) was defined at the Council of Chalcedon (451 AD). Catholic teaching on Christ's death, resurrection, ascension, and return at the end of time is articulated in the Creed and across the liturgical year.

Catholic teaching holds Scripture and Sacred Tradition as the two-fold transmission of the deposit of faith, both interpreted authoritatively by the Magisterium (the teaching office of the Church). The Catholic biblical canon includes the deuterocanonical books (Tobit, Judith, 1-2 Maccabees, Wisdom, Sirach, Baruch, plus additions to Esther and Daniel) not in most Protestant Bibles. The principal English-language Catholic Bibles in the US are the NABRE (used in the Mass), the Revised Standard Version Catholic Edition (RSV-CE), and the Douay-Rheims (traditionalist communities).

Catholic teaching distinguishes seven sacraments: Baptism, Confirmation, Eucharist, Penance / Reconciliation, Anointing of the Sick, Holy Orders, and Matrimony. The sacraments are understood to confer grace ex opere operato (by the working of the rite itself, where the recipient does not place an obstacle), distinguishing Catholic sacramental theology from the symbolic / memorialist readings of some Protestant traditions.

Catholic teaching holds that at the Mass's consecration, the bread and wine become the body and blood of Christ, the doctrine of transubstantiation, defined at the Council of Trent (1545-1563). The Eucharistic real presence is the center of Catholic devotional life; Eucharistic adoration (the host displayed for prayer outside the Mass) is a distinctive Catholic practice. The Mass is offered both as the unbloody re-presentation of Christ's sacrifice and as the meal of the Church.

Catholic teaching distinguishes the worship (latria) reserved to God from the veneration (dulia) given to saints and the special veneration (hyperdulia) given to Mary the Mother of God. The four Marian dogmas are Mother of God / Theotokos (defined 431), Perpetual Virginity (held from the early Church; defined formally at the Lateran Synod of 649), Immaculate Conception (defined 1854), and Assumption (defined 1950). Prayer to Mary and the saints is asking for their intercession, not worship; the Catholic understanding distinguishes asking the saints for prayer from praying to them as gods.

The Catholic Mass is the central liturgical act of Catholic life. The Sunday obligation (the duty to attend Mass on Sundays and Holy Days of Obligation) is part of Catholic practice. The Mass's structure: the Introductory Rites (gathering, penitential act, Gloria), the Liturgy of the Word (Old Testament reading, responsorial psalm, New Testament epistle, Gospel, homily, Creed, prayers of the faithful), the Liturgy of the Eucharist (preparation of gifts, Eucharistic Prayer with the consecration, the Lord's Prayer, the sign of peace, Communion), and the Concluding Rites (final blessing, dismissal). The Mass takes 50-75 minutes in most US parishes.

A typical Catholic life passage: infant Baptism (usually within months of birth), First Reconciliation and First Communion (typically age 7-8), Confirmation (typically 8th grade or high school in most US dioceses; immediately after baptism in Eastern Catholic practice), Matrimony or Holy Orders (vocational), and Anointing of the Sick (at serious illness or near death). The sacraments are celebrated within the parish; the parish priest is the principal sacramental minister.

Catholic life follows the liturgical year: Advent (four weeks before Christmas), Christmas Season (Christmas Day through the Baptism of the Lord), Ordinary Time (the longest stretch, in green vestments), Lent (40 days before Easter, in violet), the Easter Triduum (Holy Thursday, Good Friday, Easter Vigil), Easter Season (50 days), and back to Ordinary Time. Major feasts (Solemnities) are observed with substantial liturgical weight. The liturgical year structures Catholic devotional and parish life.

Daily Catholic prayer includes morning and evening prayer (often from the Liturgy of the Hours, the Church's official prayer cycle), grace at meals, and the rosary (twenty decades typically prayed across a week). Many Catholics participate in daily Mass at least occasionally; some attend daily. Weekly confession was the historical Catholic practice; monthly or seasonal confession is more typical in modern US Catholic life. Prayer to saints, especially patron saints and Mary, is integrated throughout.

Catholic devotional life is layered alongside the liturgical: the rosary, novenas (nine-day prayer cycles), the Divine Mercy chaplet, the Sacred Heart devotion, the Stations of the Cross (especially in Lent), Eucharistic adoration, the wearing of scapulars and medals, pilgrimages, processions. Different Catholic communities emphasize different devotions; Hispanic Catholic, Italian Catholic, Polish Catholic, Filipino Catholic, and Irish Catholic devotional traditions each carry distinctive emphasis.

Lay Catholic life includes participation in lay associations and movements: the Knights of Columbus, the Legion of Mary, the Catholic Worker movement, Opus Dei, the Cursillo Movement, the Charismatic Renewal, the Neocatechumenal Way, Catholic Worker movement, parish ministries (lectors, Eucharistic ministers, CCD catechists), and Catholic schools and universities. The lay vocation is theologically substantial in Catholic teaching (the universal call to holiness, the lay apostolate); lay involvement in the Church's life is the principal way most Catholics live the tradition.

A movement within US Catholic life favoring the pre-Vatican II liturgy (the Tridentine Latin Mass, formalized after the Council of Trent) and pre-Conciliar devotional practices. The Society of Saint Pius X (SSPX) is in irregular communion with Rome over disputes following Vatican II; the Priestly Fraternity of Saint Peter (FSSP), the Institute of Christ the King Sovereign Priest (ICKSP), and other Ecclesia Dei communities celebrate the Latin Mass in regular communion. Pope Francis's 2021 motu proprio Traditionis Custodes restricted the Latin Mass's celebration in some places; the question is contested. Traditionalist Catholics in regular communion are a small but growing US Catholic subset.

The principal lived form of US Catholicism since Vatican II (1962-1965). The Mass is celebrated in English (or another vernacular) facing the people; lay participation is substantial; the role of the laity has expanded; ecumenical engagement with other Christian traditions is part of normal parish life. The Catechism of the Catholic Church (1992, revised 1997) is the principal magisterial summary; the New American Bible Revised Edition (NABRE) is the principal liturgical Bible. Most US Catholics worship in this register.

Twenty-two Eastern Catholic Churches in communion with Rome maintain their own liturgical rites (distinct from the Roman Rite) while accepting papal primacy and the principal Catholic teachings. The largest in the US are the Maronite Catholic Church (Lebanese tradition), the Melkite Greek Catholic Church, the Ukrainian Greek Catholic Church, the Ruthenian Catholic Church, the Chaldean Catholic Church (Iraqi tradition), the Syro-Malabar Church (Indian tradition), and the Armenian Catholic Church. Eastern Catholic married priests are normal; Eastern Catholic liturgical year differs from Roman Rite in some details; Eastern Catholic devotional life retains distinctive traditions from the parent ancient Christian communities.

Approximately 40% of US Catholics identify as Hispanic / Latino, with substantial Mexican-American, Puerto Rican, Cuban-American, Dominican-American, Central American, and Colombian-American communities. Hispanic Catholic devotional life carries distinctive traditions: the quinceañera, Las Posadas (the nine-day pre-Christmas processions), Día de los Muertos (the observance of the dead alongside All Saints / All Souls), the substantial devotion to Our Lady of Guadalupe and the regional Marian patronesses, the Misa de Gallo / Simbang Gabi traditions in Filipino and Hispanic Catholic communities. The Hispanic Catholic presence is the largest growing segment of US Catholic life.

Italian, Polish, Irish, German, Hungarian, Lithuanian, Croatian, and other European-heritage Catholic communities maintain distinctive devotional and cultural traditions within US Catholicism. Italian Catholic feast-day processions, Polish Catholic Easter food blessing (swieconka), Irish Catholic devotion to St. Patrick and the family rosary, and the regional parish patron saints in immigrant neighborhoods carry the local Catholic memory.

Filipino Catholic (~3.7 million in the US), Vietnamese Catholic (~600K), Korean Catholic, Indian Catholic (across Latin Rite and Syro-Malabar), and Chinese Catholic communities each carry distinctive traditions. Filipino Catholic Simbang Gabi (the nine-day novena Masses before Christmas), Vietnamese Catholic devotion to Our Lady of La Vang, and other regional patron-saint devotions are substantial within US Catholicism.

The Tridentine Latin Mass's celebration in modern US Catholic life is one of the principal internal disputes. Traditionalists hold the pre-Conciliar Mass as the principal Catholic liturgy, restored under Pope Benedict XVI's 2007 Summorum Pontificum, restricted again under Pope Francis's 2021 Traditionis Custodes. The question is contested within the Catholic episcopate and within US parishes. Decision 10 applies: the site notes the dispute and the magisterial documents without taking a position on which celebration is the right one.

Catholic teaching holds that ordination to the priesthood and episcopate is reserved to men. Pope John Paul II's 1994 Apostolic Letter Ordinatio Sacerdotalis stated that the Church has no authority to ordain women. The teaching is contested from outside the Catholic Church (most Mainline Protestant traditions ordain women); the question is closed within Catholic teaching though publicly discussed. Women serve in many lay ministries, in the consecrated religious life, and as lay theologians and administrators; the female diaconate is under historical and theological discussion.

Catholic teaching distinguishes between the moral judgment of homosexual acts (held in Catholic teaching as objectively contrary to natural law) and the pastoral care of homosexual persons (called to chastity, welcomed in the Church, treated with respect). The pastoral application varies sharply between US dioceses, parishes, and Catholic communities; Pope Francis's pontificate has emphasized accompaniment and respect, while teaching has not changed. The question is one of the principal contemporary US Catholic pastoral discussions.

Catholic teaching (Humanae Vitae, 1968) holds artificial contraception as contrary to the proper end of conjugal acts. The teaching is widely not followed in practice by US Catholic married couples; survey data consistently shows the gap between magisterial teaching and lived practice. The teaching also shapes Catholic positions on abortion (categorically opposed, considered the principal life issue), IVF (contested in Catholic teaching), and embryonic stem cell research.

The Catholic teaching that Scripture and Sacred Tradition are co-equal sources of revelation, interpreted authoritatively by the Magisterium, is the principal Reformation-era dispute with Protestant Christianity. Most Protestant traditions hold sola scriptura (scripture alone as the principal authority); the Catholic understanding differs sharply. The deuterocanonical books in the Catholic canon are accepted in part because of their inclusion in the Septuagint and in tradition; Protestant traditions reject them on the basis of their absence from the Hebrew canon.

Catholic teaching holds that the Pope is the visible head of the Church on earth, the successor of Peter, and (under specific conditions) infallible in matters of faith and morals. Papal authority is contested from outside the Catholic Church by Orthodox Christianity (which accepts the Pope as bishop of Rome but not as universal head) and by Protestantism (which rejects papal primacy entirely). The 1870 First Vatican Council's definition of papal infallibility is the principal modern articulation of the teaching.
