22 And this work of the Church in every branch of culture is of immense benefit to families and nations which without Christ are lost, as St. Hilary points out correctly: "What can be more fraught with danger for the world than the rejection of Christ?" Nor does it interfere in the least with the regulations of the State, because the Church in her motherly prudence is not unwilling that her schools and institutions for the education of the laity be in keeping with the legitimate dispositions of civil authority; she is in every way ready to cooperate with this authority and to make provision for a mutual understanding, should difficulties arise.
