Templar Studies : The Beauceant

As exoteric heraldic display goes, the Beauceant is an extremely simple Blazon. Since there are no charges on the field anywhere, the heraldic description would be something to the effect of: "Party per fess, agent & sable."

IMHO - however, the Beauceant is deceptive in it's simplicity. Quite without the use of charges and/or embellishments it's message is both powerful and profound. In its juxtaposition of black and white, one is reminded of the Kabbalistic "Pillars of the Temple"...Boaz (Black) and Jachin (White)...within whose sway "Might and Mercy" reside.

For me, this interpretation of the banner makes sense. In a book I recently read, the author indicates that the Templars used the following "Challenge" before engaging the enemy in battle: "In the Name of the Lord Almighty I call upon you to relinquish your weapons and receive the Mercy of Christ the King."

... Note the wording on the bolded sections (i.e. the "Might" of God, and the Mercy of Christ).
If it is indeed true that this Challenge was used, then I find this to be (at the very least) an interesting coincidence...
