Stars, Moon and Cross
Long before words were used to communicate, humans used pictures. Long before religions became organized institutions, humans used particular symbols to represent their religion. These symbols are often found in the rituals of the particular religions.
The three most widely recognized world religion symbols are the Star of David, the Star and Crescent Moon and the Cross.
The Star of David is the symbol of Judaism. The star is has six points created by two triangles. Anthropologic researchers believed that the triangles were used to symbolize male (pointing up) and female (pointing down), thereby denoting unity, balance or harmony.
In Judaism, the Star is referred to as Magen David, which means, literally, Shield of David. Interestingly, in ancient times, the Menorah was symbolic of Judaism, not the Star, which was believed to be a symbol used by Kabbalists. It was also known as the Seal of Solomon. Modern Jewish scholars write that the six-pointed star is the reminder of God's rule over all. The six points represent the four cardinal directions (north, south, east, west) as well as up and down.
While there is no reference to the Star in the Talmud, some scholars believe the use of the Star came about in the first century when warriors made shields using two inverted triangles.
Islam has no official symbols. However, the Star and Crescent Moon are recognized today as the symbol of Islam, mainly due to the use of the symbol on national flags. Variations of this symbol, which is reported by scholars to be an ancient polytheistic sign, can be found in artifacts from ancient times throughout the Eastern Mediterranean and Central Asia. Historians trace the emblem to its use by the Ottomans who spread Islam during their time.
While the Star and Crescent Moon are found on the flags of various Islamic dynasties, the colors vary. The green Star and Crescent is symbolic, according to researchers, of life and vegetation, which recalls the belief that the inhabitants of Paradise will wear clothes of the finest green silk.
The Cross is the symbol of Christian faiths. Christians are followers of Jesus, who they believe was the promised messiah of ancient (Old Testament) writings. Jesus, a Jew, was killed by the Romans who were afraid that he was raising the population against them with his radical teachings of love and brotherhood. The common form of execution at that time was for criminals to be nailed to a cross until dead. Other symbols of Christianity are the Fish (Jesus was a "fisher of men"), the Butterfly (Resurrection and new life) and the Dove (Peace and the Holy Spirit).
