Mary, mother of Jesus in the context of "Saint Joseph"

An icon (from Ancient Greek εἰκών (eikṓn) 'image, resemblance') is a religious work of art, most commonly a painting, in the cultures of the Eastern Orthodox, Oriental Orthodox, Catholic, and Lutheran churches. The most common subjects include Jesus, Mary, saints, and angels. Although especially associated with portrait-style images concentrating on one or two main figures, the term also covers most of the religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes, usually from the Bible or the lives of saints.

Icons are most commonly painted on wood panels with egg tempera, but they may also be cast in metal or carved in stone or embroidered on cloth or done in mosaic or fresco work or printed on paper or metal, etc. Comparable images from Western Christianity may be classified as "icons", although "iconic" may also be used to describe the static style of a devotional image. In the Greek language, the term for icon painting uses the same word as for "writing", and Orthodox sources often translate it into English as icon writing.

Theotokos (Koine Greek: Θεοτόκος) is a title of Mary, mother of Jesus, used especially in Eastern Christianity. The usual Latin translations are Dei Genitrix or Deipara (approximately "parent [fem] of God"). Common English translations are "Mother of God" or "God-bearer" – but these both have different literal equivalents in Ancient Greek: Μήτηρ Θεοῦ, and Θεοφόρος respectively.

The title has been in use since the 3rd century, and in the Liturgy of Saint James (4th century). The Council of Ephesus in AD 431 decreed that Mary is the Theotokos because her son Jesus is both God and man: one divine person from two natures (divine and human) intimately and hypostatically united.

Marian devotions are external pious practices directed to the person of Mary, mother of Jesus, by members of certain Christian traditions. They are performed in Catholicism, High Church Lutheranism, Anglo-Catholicism, Eastern Orthodoxy and Oriental Orthodoxy, but other Christian denominations mostly reject them.

Such devotional prayers may be accompanied by specific requests for Mary's intercession with God. There is significant diversity of form and structure in Marian devotions practiced by different groups of Christians. Orthodox Marian devotions are well-defined and closely linked to liturgy, while Roman Catholic practices are wide-ranging—they include multi-day prayers such as novenas, the celebration of canonical coronations granted by the Pope, the veneration of icons in Eastern Christianity, and pious acts which do not involve vocal prayers, such as the wearing of scapulars or maintaining a Mary garden.

Pentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday that takes place on the 49th day (50th day when inclusive counting is used) after Easter. It commemorates the descent of the Holy Spirit upon the Apostles of Jesus, Mary, and other followers of the Christ, while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31). Pentecost marks the "Birthday of the Church".

Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion. Many Christian denominations provide a special liturgy for this holy celebration. Since its date depends on the date of Easter, Pentecost is a "moveable feast". The Monday after Pentecost is a legal holiday in many European, African and Caribbean countries.

Stained glass refers to coloured glass as a material or art and architectural works created from it. Although it is traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture. Modern vernacular usage has often extended the term "stained glass" to include domestic lead light and objets d'art created from glasswork, for example in the famous lamps of Louis Comfort Tiffany.

As a material stained glass is glass that has been coloured by adding metallic salts during its manufacture. It may then be further decorated in various ways. The coloured glass may be crafted into a stained-glass window, say, in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead, called cames or calms, and supported by a rigid frame. Painted details and yellow-coloured silver stain are often used to enhance the design. The term stained glass is also applied to enamelled glass in which the colors have been painted onto the glass and then fused to the glass in a kiln.

Christmas is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A liturgical feast central to Christianity, Christmas preparation begins on the First Sunday of Advent and it is followed by Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night. Christmas Day is a public holiday in many countries, is observed religiously by a majority of Christians, as well as celebrated culturally by many non-Christians, and forms an integral part of the annual holiday season.

The traditional Christmas narrative recounted in the New Testament, known as the Nativity of Jesus, says that Jesus was born in Bethlehem, in accordance with messianic prophecies. When Joseph and Mary arrived in the city, the inn had no room, and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds, who then spread the word.

Mary, the mother of Jesus in Christianity, is known by many different titles (Blessed Mother, Virgin Mary, Mother of God, Our Lady, Holy Virgin, Madonna), epithets (Star of the Sea, Queen of Heaven, Cause of Our Joy), invocations (Panagia, Mother of Mercy, God-bearer Theotokos), and several names associated with places (Our Lady of Loreto, Our Lady of Fátima).

All of these descriptives refer to the same woman named Mary, the mother of Jesus Christ (in the New Testament). They are used differently by Catholics, Eastern Orthodox, Oriental Orthodox, and some Anglicans. (Note: Mary Magdalene, Mary of Clopas, and Mary Salome are different women.)

The perpetual virginity of Mary is a Christian doctrine that Mary, the mother of Jesus, was a virgin "before, during and after" the birth of Christ. In Western Christianity, the Catholic Church adheres to the doctrine, as do many Lutherans, some Anglicans, Reformed, and other Protestants. In Eastern Christianity, the Oriental Orthodox Churches and the Church of the East both adhere to this doctrine as part of their ongoing tradition, and Eastern Orthodox churches recognize Mary as Aeiparthenos, meaning "ever-virgin". It is one of the four Marian dogmas of the Catholic Church. Most modern nonconformist Protestants, such as the Plymouth Brethren, reject the doctrine.

The extant written tradition of the perpetual virginity of Mary first appears in a late 2nd-century text called the Protoevangelium of James. The Second Council of Constantinople in 553 gave her the title "Aeiparthenos", meaning Perpetual Virgin, and at the Lateran Synod of 649 Pope Martin I emphasized the threefold character of the perpetual virginity, before, during, and after the birth of Christ. The Lutheran Smalcald Articles (1537) and the Reformed Second Helvetic Confession (1562) codified the doctrine of perpetual virginity of Mary as well.
