Crucifix in the context of "Bernward Column"

Crucifixion is a method of capital punishment in which the condemned is tied or nailed to a large wooden cross, beam or stake and left to hang until eventual death, which could take minutes to days. It was first used as a punishment by the Achaemenids, Carthaginians, and Romans, among others. Crucifixion has been used in some countries as recently as the 21st century.

The crucifixion of Jesus is central to Christianity and the cross (in Roman Catholicism usually depicted with Jesus nailed to it) is Christianity's preeminent religious symbol. His death is the most prominent example of crucifixion in history, which in turn has led many cultures in the modern world to associate the execution method closely with Jesus and with Christian spirituality. Other figures in Christianity are traditionally believed to have undergone crucifixion as well, including Saint Peter, who Church tradition says was crucified upside-down, and Saint Andrew, who Church tradition says was crucified on an X-shaped cross. Today, limited numbers of Christians voluntarily undergo non-lethal crucifixions as a devotional practice.

A sacramental (Latin pl. sacramentalia) is a sacred sign, a ritual act or a ceremony, which, in a certain imitation of the sacraments, has a spiritual effect and is obtained through the intercession of the Church. Sacramentals surround the sacraments like a wreath and extend them into the everyday life of Christians. Sacramentals are recognised by the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox Churches, the Church of the East, the Lutheran churches, the Old Catholic Church, the Anglican churches, and Independent Catholic churches.

In the Bible, prayer cloths and holy oil are mentioned in reference to praying for healing. Holy water is a sacramental that the faithful use to recall their baptism; other common sacramentals include blessed candles (given to the faithful on Candlemas), blessed palms (blessed on the beginning of the procession on Palm Sunday), blessed ashes (bestowed on Ash Wednesday), a cross necklace (often taken to be blessed by a pastor before daily use), a headcovering (worn by women, especially during prayer and worship), blessed salt, and holy cards, as well as Christian art, especially a crucifix. Apart from those worn daily, such as a cross necklace or devotional scapular, sacramentals such as a family Bible, are often kept on home altars in Christian households. Ichthys emblems are sacramentals applied to vehicles to signify that the owner is a Christian and to offer protection while driving. When blessed in a betrothal ceremony, engagement rings become a sacramental.

The Christian cross, seen as symbolizing the crucifixion of Jesus, is a symbol of Christianity. It is related to the crucifix, a cross that includes a corpus (a representation of Jesus's body, usually three-dimensional) and to the more general family of cross symbols. The term cross is now detached from its original specifically Christian meaning, in modern English and many other Western languages.

The basic forms of the cross are the Latin cross with unequal arms and the Greek cross with equal arms; there are numerous variants, partly with confessional significance - such as the tau cross, the double-barred cross, triple-barred cross, and cross-and-crosslets - and many heraldic variants, such as the cross potent, cross pattée, and cross moline, cross fleury.

A cross necklace is any necklace featuring a Christian cross or crucifix as its pendant.

Crosses are often worn as an indication of commitment to the Christian faith, and are sometimes received as gifts for rites such as baptism and confirmation. Communicants of the Oriental Orthodox and Eastern Orthodox churches are expected to wear their baptismal cross necklaces at all times.

A home altar or family altar is a shrine kept in the home of some Western Christian families used for Christian prayer and family worship. Home altars often contain a cross or crucifix, an image of Jesus Christ, a copy of the Bible (especially a Family Bible), a breviary and/or other prayer book, a daily devotional, and prayer beads, among other religious articles specific to the individual's Christian denomination, for example, the images of the saints for Catholics, the Small Catechism for Lutherans, and the Anglican prayer beads for Anglicans.

The Christian cross, with or without a figure of Christ included, is the main religious symbol of Christianity. A cross with a figure of Christ affixed to it is termed a crucifix and the figure is often referred to as the corpus (Latin for "body").

The term Greek cross designates a cross with arms of equal length, as in a plus sign, while the Latin cross designates a cross with an elongated descending arm. Numerous other variants have been developed during the medieval period.
