42 What a proud vaunt it will be for the American people, by nature inclined to grandiose undertakings and to liberality, if they untie the knotty and difficult social question by following the sure paths illuminated by the light of the Gospel and thus lay the basis of a happier age! If this is to come to pass power must not be dissipated through disunion but rather strengthened through harmony. To this salutary union of thought and policy, whence flow mighty deeds, in all charity We invite them, too, whom Mother Church laments as separated brethren. Many of these, when Our glorious predecessor reposed in the sleep of the just and when We, shortly after his death, through the mysterious disposition of Divine Mercy ascended the throne of St. Peter; many of these - and this did not escape Our attention - expressed by word of mouth and by letter sentiments full of homage and noble respect. This attitude - We openly confess - has encouraged a hope which time does not take from Us, which a sanguine mind cherishes and which remains a consolation to Us in hard and troublous times.
