Freemasonry has been criticized in the past for an almost obsessive use of the term "light." Some have claimed that this "light" we proclaim is a reference to salvation instead of to knowledge or truth. "Many anti-Masons believe that the term 'light' refers to an alleged salvation available through Freemasonry. As any dictionary indicates, there are many definitions of light. The term does not always refer to Jesus Christ or Salvation. The definition is determined by the person using the term, not by the interpreter. The motto of the Baltimore Sun is 'Light for All.' Would anyone argue that the Baltimore Sun is teaching salvation in its pages? No. It uses light in the sense of knowledge or information, just as do Masons. The motto of Yale University is 'LUX' a Latin word for 'light.' The list could go on."
I find this little interesting insight in The Idaho Freemason, (Januuary, 2008): 3, 10. It is taken from the EMESSAY NOTES, Dec. 2007, original source is Dr. Gary Leazer's book Fundamentalism and Freemasonry.
