8 Let all remember that the flood of evil and disaster that has over-taken the world in past years was due chiefly to the fact that the divine religion of Jesus Christ, that provider of mutual charity among citizens, peoples and nations, did not govern, as it should, private, domestic and public life. If things have gone wrong on account of the desertion from Christ, public and private life must return to Him as soon as possible: if error has clouded the minds of men, they must return to that truth which, revealed from on high, indicates the right way to heaven: if hatred has brought them fatal results, they must return to Christian love which alone can heal their many wounds, and carry them over the crisis so filled with danger.
