What does the design made of a carpenter's square and a compass with a letter "G" represent?

The design made of a carpenter's square and a compass with the letter "G" is recognized as a prominent symbol of Freemasonry, commonly referred to as the Masonic Emblem. The carpenter's square represents morality and the compass symbolizes the boundaries of behavior, together guiding members in their ethical conduct and personal actions. The letter "G" typically stands for "God" or "Geometry," emphasizing the importance of a higher power and the significance of geometry in the Masonic tradition. This emblem serves as a reminder of the principles and moral standards that Freemasons strive to uphold in their lives and interactions with others.

In contrast, the other options represent distinct organizations with their own symbols and meanings, such as the Royal Order of the Moose and the Knights of Columbus, which have different iconography and are focused on different missions. Martin's Cross is not related to Freemasonry and has its own cultural and historical significance. Understanding these distinctions is key to recognizing the unique nature of the Masonic Emblem.
