101 It is for these reasons that We are driven to repudiate such ideologies as deny God and oppress the Church-We repudiate them as Our predecessors did, and as everyone must do who firmly believes in the excellence and importance of religion. These ideologies are often identified with economic, social and political regimes; atheistic communism is a glaring instance of this. Yet is it really so much we who condemn them? One might say that it is rather they and their politicians who are clearly repudiating us, and for doctrinaire reasons subjecting us to violent oppression. Truth to tell, the voice we raise against them is more the complaint of a victim than the sentence of a judge.
