The cross is a religious symbol with a Christian character consisting of two intersecting lines, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology. The cross has been widely officially taken as an official symbol of the Christian religion exclusively from an early period in that religion's history to present.
