43 And now We seem to have touched upon thosematters which Catholics ought chiefly nowadays to follow, or mainly to avoid. Itrests with you, venerable brothers, to take measures that Our voice may reacheverywhere, and that one and all may understand how urgent it is to reduce topractice the teachings set forth in this Our letter. The observance of theseduties cannot be troublesome or onerous, for the yoke of Jesus Christ is sweet,and His burden is light. If anything, however, appear too difficult ofaccomplishment, you will afford aid by the authority of your example, so thateach one of the faithful may make more strenuous endeavor, and display a soulunconquered by difficulties. Bring it home to their minds, as We have Ourselvesoftentimes conveyed the warning, that matters of the highest moment and worthyof all honor are at stake, for the safeguarding of which every most toilsomeeffort should be readily endured; and that a sublime reward is in store for thelabors of a Christian life. On the other hand, to refrain from doing battle forJesus Christ amounts to fighting against Him; He Himself assures us "Hewill deny before His Father in heaven those who shall have refused to confessHim on earth."(44) As for Ourselves and you all, never assuredly, so longas life lasts, shall We allow Our authority, Our counsels, and Our solicitude tobe in any wise lacking in the conflict. Nor is it to be doubted but thatespecial aid of the great God will be vouchsafed, so long as the struggleendures, to the flock alike and to the pastors. Sustained by this confidence, as a pledge ofheavenly gifts, and of Our loving kindness in the Lord to you, venerablebrothers, to your clergy and to all your people, We accord the apostolicbenediction.
