The Solemnity of the Immaculate Conception is the solemnity in the Roman Rite celebrating the dogma that Mary was preserved free from original sin from the first instant of her conception, by a singular grace of God in view of the merits of Jesus Christ. Proclaimed as dogma by Pope Pius IX in *Ineffabilis Deus* (1854), it is observed on December 8 according to the General Roman Calendar and marks the beginning of the intense preparation for Christmas. The solemnity is a Holy Day of Obligation in most dioceses worldwide, including the United States.

According to the *General Roman Calendar* (2002 edition), the Immaculate Conception ranks as a solemnity of the highest degree, taking precedence over any Sunday in Advent. The Mass uses white vestments, with proper texts in the Missale Romanum proclaiming Mary as the new Eve and Ark of the Covenant. The Gloria and Creed are recited, and a Vigil Mass is available on December 7.

The feast, distinct from the virgin birth of Christ, underscores Mary's unique holiness as fitting for the Mother of God, a belief rooted in early Church Fathers and defined in the 19th century.

Liturgical observance

The Mass employs white vestments. The Lectionary prescribes Genesis 3:9–15, 20 (the protoevangelium), Ephesians 1:3–6, 11–12 (predestination in Christ), and Luke 1:26–38 (the Annunciation). Missale Romanum (editio typica tertia ed.). Libreria Editrice Vaticana. 2002.  Lectionary for Mass. I. United States Conference of Catholic Bishops. 2002. 

The Preface of the Immaculate Conception is proper, highlighting God's preventive grace. No special rites are mandated universally, though the Liturgy of the Hours includes the hymn Tota pulchra es. Local dioceses may incorporate consecrations to Mary, but these are devotional.

History

Evidence suggests the feast originated in the Eastern Church by the 7th century under the title “Conception of Saint Anne,” spreading to the West where Franciscan theologians like John Duns Scotus defended the doctrine of preservation from sin. The Catholic Encyclopedia. 7. Robert Appleton Company. 1910. https://www.newadvent.org/cathen/07674d.htm.  In 1476, Pope Sixtus IV approved the feast for the Roman calendar on December 8.

The dogma was solemnly defined by Pius IX on December 8, 1854, in St. Peter’s Basilica, amid growing Marian devotion. The 1969 reform retained December 8 as a solemnity with Vigil."Mysterii Paschalis". Vatican. 1969-02-14. https://www.vatican.va/content/paul-vi/en/motu_proprio/documents/hf_p-vi_motu-proprio_19690214_mysterii-paschalis.html.  This reflects universal Roman Rite observance; Eastern Catholic churches celebrate the Conception of the Theotokos on December 9.

Theological significance

The Immaculate Conception affirms Mary's total sanctity as necessary for her divine motherhood. The Catechism of the Catholic Church teaches: “By the grace of God Mary remained free of every personal sin by her whole life” (CCC 491), preserved from original sin in anticipation of Christ's redemption. Catechism of the Catholic Church (2nd ed.). Libreria Editrice Vaticana. 1997. 

Genesis 3:15 foretells enmity between the woman and the serpent, fulfilled in Mary. Ephesians 1:4–5 speaks of being chosen before the foundation of the world. Pope Pius IX declared in *Ineffabilis Deus* that this grace adorns Mary with “the splendor of entirely unique holiness.”"Ineffabilis Deus". Vatican. 1854-12-08. https://www.vatican.va/content/pius-ix/en/apost_constitutions/documents/hf_p-ix_apc_18541208_ineffabilis-deus.html. 

Veneration and traditions

Liturgical tradition holds that the Immaculate Conception is honored through Mass and recitation of the Hail Mary. According to popular devotion, the Miraculous Medal (associated with the 1830 apparitions to St. Catherine Labouré) promotes the feast, though this is not liturgical.

Processions or novenas occur in Spain, Portugal, and Latin America on December 8, but are local customs. No universal foods are prescribed; blue and white decorations symbolize purity in some regions. The title “Immaculate Conception” is invoked in the Litany of Loreto.
