Some common Christian symbols include the cross, a lamb, a fish and a dove. Although many of the symbols represent general identification as Christian, some symbols are specialized to represent different aspects of religious belief or different branches of Christianity.
The cross is the most popular of Christian symbols since it represents the crucifixion of Jesus. There are variations of the cross which are used by different branches of the Christian church or by different cultures. For example, the Slavonic cross is commonly used in Slavic countries that are predominantly Catholic. In other Catholic-dominated countries, a crucifix depicting Jesus on the cross is more common.
Other symbols, such as a lamb or dove, represent Jesus and the Holy Spirit, respectively. The fish is one of the oldest symbols of Christianity. It stands for the Greek word for fish, "ichthys," which was spelled "IXOYE" and was an acronym for "Jesus Christ, Son of God Savior."
