In all the Lodges under the jurisdiction of the Grand Lodge of the State of Louisiana (and many other Grand Jurisdictions) the VOSL is open at the Seventh Chapter of Amos in the FC Degree.
Why do we do this?
This practice is not universal, but ours has the sanctity of long use and sacredness. Also, since one of the working tools of a FC is the Plumb, it is appropriate to open the Bible at the story about the plumb line of God. What do we really know about this man, the prophet Amos? Do we know why the God called him to deliver His message of judgment to His people of Israel?
