Christian symbolism is the use of signs and emblems to present religious truths. Words often fail where symbolism succeeds, while taken together they frequently make spiritual things more fully grasped. Numerous signs and symbols, many of them associated with worship, have developed over the two thousand years of Christianity. The most immediately recognizable Christian symbol is the cross, a simple pictorial representation of the wooden structure upon which Jesus was crucified. A number of variations of this symbol can be seen in churches and art, and on jewelry and other objects used in daily life. The most common variations are the Latin cross, the Greek cross, and the crucifix, which is a cross that depicts the body of the suffering Christ.
