... never to hesitate, never to relax,...

Virgin countries and territories opened during
the first year of the 10 Year Crusade

No matter how long the period that separates them from ultimate victory; however arduous the task; however formidable the exertions demanded of them; however dark the days which mankind, perplexed and sorely-tried, must, in its hour of travail, traverse; however severe the tests with which they who are to redeem its fortunes will be confronted; however afflictive the darts which their present enemies, as well as those whom Providence, will, through His mysterious dispensations raise up from within or from without, may rain upon them, however grievous the ordeal of temporary separation from the heart and nerve-center of their Faith which future unforeseeable disturbances may impose upon them, I adjure them, by the precious blood that flowed in such great profusion, by the lives of the unnumbered saints and heroes who were immolated, by the supreme, the glorious sacrifice of the Prophet-Herald of our Faith, by the tribulations which its Founder, Himself, willingly underwent, so that His Cause might live, His Order might redeem a shattered world and its glory might suffuse the entire planet — I adjure them, as this solemn hour draws nigh, to resolve never to flinch, never to hesitate, never to relax, until each and every objective in the Plans to be proclaimed, at a later date, has been fully consummated.
