13 All these things, Venerable Brethren, which Our affection for the Scottish people has suggested to Us, we commend to your thoughtfulness and charity. Continue to exercise that zeal of which you have given Us such abundant proof, so that everything may be effected which may conduce to the realization of what we have in view. The matter in hand is extremely difficult, and one the accomplishment of which, as We have repeatedly stated, surpasses all human efforts; but it is most holy and desirable, and in perfect harmony with the counsels of Divine Goodness. Wherefore, We are not so much deterred by the difficulties, as We are encouraged by the conviction that the Divine help will not fail, if you devote yourselves to the fulfilment of these Our wishes and behests.
