Have you ever wondered about the origin of different signs and symbols we use? I'm not one to take another's pet traditions as truth, so I like to research things from both the Christian and non-Christian point of view. For instance, the peace symbol.
I've always been told that the inverted cross was a satanic symbol. And yet, I'm seeing more and more Christian young people sporting it. So, today, I decided to do a little search. I found several different explanations available. So, after reading several of them, I decided to take a look at the oldest available mention.
The oldest use of the "Peace" symbol dates back to the early Christian era. It did indeed mean peace, but it didn't stop there. You see, Nero, used it to symbolize world peace without Christianity. Tradition states that Peter was crucified upside down. Although we don't know this for certain, we do know that even today, the upside down cross is used to symbolize opposition to Christ, Who, as we know, was crucified on a Roman cross. The circle is used in Satanic religions to mean that something is complete. Nero used this symbol to show his intentions to eradicate Christianity and, therefore, to bring world peace.
That said, we need to remember, that most Christians today are not aware of the history of the peace symbol. They wear it as a statement of true peace, the peace that only God can bring to a troubled soul. It is not for us to correct every well-meaning person that walks into our churches. I personally, will never wear a peace symbol, but I will not dictate the lives of others.
I simply thought it was interesting to see the uses of the peace symbol throughout history. Do your own search and see what you come up with. Don't take the word of tradition. God's Word says to "study to show thyself approved..." If its not black-and-white in Scripture (you know, "Thou shalt not...") be careful that your not following the traditions of men. Never take a stand until you know why you're standing and can back it up.
