52 In the meantime, though We are quite conscious that it is not necessary for Us to exhort you to greater and more zealous efforts but rather to bestow on you the praise which you so richly deserve, yet the very consciousness of Our Apostolic Office, of the fact that We are the Common Father of all, constrains Us to beseech you to exhibit at all times a very special and tender love toward that large family of spiritual children which is, in a very special way, committed to your immediate supervision. From the reports received from you by Us and by public fame, which is amply confirmed in the press and in many other ways, We know only too well what thanks we should, in union with you, render to the Good God for the great work which, as the occasion permitted, He has done through you and through your predecessors, both for your clergy and for your faithful people, a work which has come to maturity in our own times and which We see being multiplied on all sides in a most fruitful manner.
