8 Unfortunately, as all know, Our wishes and desires were not followed by the peace and favourable settlement for which We had hoped. On the contrary, to Bishops, priests, and faithful Catholics continued to be penalized and imprisoned, contrary to the spirit in which the modus vivendi had been established. To Our great distress We saw that not merely were all the Bishops not recalled from exile, but that others were expelled without even the semblance of legality. In several dioceses neither churches nor seminaries, Bishops' residences, nor other sacred edifices, were restored; notwithstanding explicit promises, priests and laymen who had steadfastly defended the faith were abandoned to the cruel vengeance of their adversaries. Furthermore, as soon as the suspension of public worship had been revoked, increased violence was noticed in the campaign of the press against the clergy, the Church, and God Himself; and it is well known that the Holy See had to condemn one of these publications, which in its sacrilegious immorality and acknowledged purpose of anti-religious and slanderous propaganda had exceeded all bounds.
