Maximam Gravissimamque §13

¹³ With reference to the guaranties sought by Us, they are not as a matter of fact precisely those which We asked for at the beginning of the negotiations and to which the heads of the French Government gave their consent. However, the guaranties actually offered are of such character and are based on such reasons and such explicit declarations that We have thought it possible to accept them in the interests of a more general peace. We have done this, too, because it did not appear possible to obtain better guaranties and because those which we proposed can, all things considered, be accepted as possessing both the legality and the security which Pius X himself would have demanded of such guaranties in the circumstances.
