49 Let this be well borne in mind by all who are in the habit of publishing their opinions, and above all by journalists. In the endeavour to secure interests of the highest order there is no room for intestine strife or party rivalries; since all should aim with one mind and purpose to make safe that which is the common object of all - the maintenance of religion and of the State. If, therefore, they have hitherto been dissensions, let them henceforth be gladly buried in oblivion. If rash or injurious acts have been committed, whoever may have been at fault, let mutual charity make amends, and let the past be redeemed by a special submission of all to the apostolic see. In this way Catholics will attain two most excellent results: they will become helpers to the Church in preserving and propagating Christian wisdom, and they will confer the greatest benefit on civil society, the safety of which is exceedingly imperiled by evil teachings and bad passions.
