There are a few different styles of the cross. The Greek cross has four equal arms, while the Latin cross has a longer base. Other crosses include St. Anthony's cross, which resembles a capital "T," and St. Andrew's cross, which looks like an "X." In modern Christianity, the Latin cross is mainly used.
To Christians, the cross is a symbol of Jesus' conquering of death and his resurrection as portrayed in the New Testament of the Bible. Jesus was condemned to death on the cross, which was a common execution of the time. However, Jesus rose from the dead, and his suffering and selfless sacrifice redeemed the world of its sins.Learn more about Symbolism
