Ubi Arcano Dei Consilio §65

⁶⁵ The Church does not desire, neither ought she to desire, to mix up without a just cause in the direction of purely civil affairs. On the other hand, she cannot permit or tolerate that the state use the pretext of certain laws of unjust regulations to do injury to the rights of an order superior to that of the state, to interfere with the constitution given the Church by Christ, or to violate the rights of God Himself over civil society.
