I'll add a little...The pyramid and eye is definitely NOT related to Masons at all...The Masons are a "secret" society, similar to a fraternity in many ways, with lots of rituals and ceremonies. While members are not required to be Christians, they are require to believe in some form of higher power, and it is generally considered a Christian organization. There are different levels, and one of the highest levels makes one a Shriner. Shriners, as you may know, are the guys who wear the funny little hats and ride in the tiny cars in parades. This isn't their main purpose. They raise money for children's burn centers and other charitable organizations. The organization does a lot of good, but depending upon where you live, may have a poor reputation due to a lack of knowledge regarding what they actually do. (I'm not a mason, I'm just a girl in college FYI) The main symbol that I know is the square and compass...Masons are generally referred to as being a part of the Society of Freemasons.
