Information on the Masonic Knights Templar’s I noted when studying Freemasons a few years ago, you are correct Christian fundamentalists oppose these organizations.
An accurate portrayal of true Freemasonry, which is based on Kabbalism ‘assimilated by the Knights Templar’ who occupied the Holy Land during the Crusades..... The Masonic emphasis on Old Testament types and figures is, in fact, derived from Kabbalah, which symbolism is designed to lead men into the ancient mysteries.
‘All Knights Templar are members of the world’s oldest fraternal organization known as ‘The Ancient Free and Accepted Masons’ or more commonly known as ‘masons.’........ However, not all masons are Templars. Templary is but a part of the Masonic structure known as the ‘York Rite of Freemasonry.’”
According to Masons:
The Rank of ‘Knight Commander’ of the Court of Honor is not a Degree, but an Investiture, bestowed upon members deserving recognition for faithful services to the Rite or to mankind. At the biennial session of the Supreme Council, certain Masters of the Royal Secret are chosen to be invested with the Rank and Decoration of Knight Commander of the Court of Honour. The respective Sovereign Grand Inspectors General or Deputies nominate members for this honor, and they must also be unanimously approved by The Supreme Council.
This Investiture is a prerequisite to receiving the Thirty-third Degree.
And there are many Muslim Masons in the World. So?
