I am quite sure that we differ in our ideas of what religious liberty means. The Catholic Church would give everybody the liberty to be religious. But liberty to propagate any religion at all is another matter. The abuse and misuse of liberty and freedom are dangerous things. A man can be subject to erroneous religions and free from the true religion. Or he can be subject to the true religion and free from erroneous religions. However, you evidently mean freedom to maintain and propagate any religion or all religions. To that thought I would say this. If all in America were Catholics, the Church would rightly forbid the danger to their faith by the introduction of error. But if erroneous religions were already established and their adherents were in good faith, the Church would permit their continued existence and liberty. And such is the case at present. The non-Catholics in America have never been her subjects, and she is not called upon to adopt such general protective measures as would be the case in a completely Catholic nation.
