47 "In omnibus teipsum praebe exemplum bonorum operum. In all things give an example of good works; that is, of active and exemplary life, animated by a true spirit of charity and guided by the maxims of evangelical prudence-of a life of sacrifice and toil, consecrated to the welfare of your neighbors, not with earthly views or for a perishable reward, but with a supernatural object. Give an example by that language at once simple, noble and lofty, by that sound and blameless discourse which confounds all human opposition, calms the long standing hatred the world has sworn against you, and wins for you the respect and even esteem of the enemies of religion. Every one devoted to the service of the sanctuary has been at all times obliged to show himself a living model and perfect exemplar of all the virtues; but this obligation becomes all the more instant when, as a consequence of social upheavals, we are treading a difficult and uncertain path where we may at every step discover ambushes and pretexts of attack. . . .
