11 It will not be useless for you to turn your mind and soul also to those things which do not glow with the light of glory. But it is Our intention at present, while you are about to celebrate the auspicious and illustrious deeds of your reowned fatherland with many solemnities, to exhort you with fatherly concern to recall those distinguished deeds which so many of the sowers of evangelical truth among you have accomplished; then you also will feel yourselves drawn again and again to the zeal of this apostolate of your ancestors .
