Use a search engine and type in “Knights of Columbus.” You will find everything you need to know about the history and mission of the KofC. It is a fraternal order and the “secrecy” was to encourage Catholic men to be a member of their own society. These secret societies were prevalent in the late 1800s, when the KofC was founded, as I explained. The 4 Degees in order are: Charity, Unity, Fraternity, and Patriotism. The Supreme Council is the National Organization, which runs everything. They are the ones who decreed doing away with the feathered hats and going with the berets. Saying they are “Gatekeepers of the Cabal” is laughable.
The name “Christopher” does mean “God Bearer” in Greek, from the story of St. Christopher carrying the Christ Child across a dangerous stream. Again, this info can be found via search engine.
