Freemasonry consist of a course of moral and philosophical instruction illustrated by symbols and taught by allegory. The men of this lodge are actively engaged in the betterment of one another, for, this is what Freemasons do. Eureka Lodge #20 is one chapter of a fraternity that spans all of time and space -that is, around the entire world and throughout most of history.

The History of Freemasonry

first degree trestle boardThe origins of Freemasonry are not quite known to anybody alive. The truth gets lost somewhere in between the details of the historical and legendary stories of the craft. It's legends take us back to the building of King Solomon's temple in Jerusalem circa 1000 BC; history teaches that the first lodges emerged from the stone masons' guilds of the middle ages in Europe; there are stone engravings of the square, compasses, level, plumb, and trowel (the working tools of Freemasonry) excavated from Egyptian archaeological sites that date back to 3000 B.C.

Freemasonry is a dynamic institution, and now our online presence will more fully reflect that.

They have demanded that I should say that something; and, though unaffectedly reluctant to do it, my obligation as a Mason bars against me all the avenues of escape, and compels disinclination to yiels to the imperative mandate of duty.

It would need no argument to show that to the Masonic Order itself, as to any other order or association, however unpretending and unimportant, intestine dissentions, struggles for the possession of power, jealousies and heart-burnings must necessarily be harmful, retard its growth and progress, repel those who, if it were at peace with itself, would seek to approach its doors; and at first diminish and ultimately destroy its capacity for usefulness.
