2 For Ourselves, never since, by the hidden designs of God, We were raised to the Chair have We ceased to do everything in Our power from the very beginning of the war that all the nations of the world might resume cordial relations as soon as possible. To that end We never ceased to pray, to repeat exhortations, to propose ways of arrangement, to try every means, in fact, to open by divine aid, a path to a just, honourable and lasting peace; and at the same time We exercised all Our paternal care to alleviate everywhere that terrible load of sorrow and disaster of every sort by which the immense tragedy was accompanied.
