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.
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.
