Page 782. B. It is absurd that there should be a law in cities that it is not lawful to divulge sacred mysteries to the uninitiated, but that one may speak of the true rites and ceremonies which lead to piety and holiness to ears full of folly. All men must not partake of all things, nor of all discourses, above all, of such as are sacred; for those that desire to be admitted to a participation in such things, ought to have many qualifications beforehand. In the first place, what is the greatest and most important, they ought to have deep feelings of piety towards the only true and living God, and correct notions of holiness, avoiding all inextricable errors which perplex so many about images and statues, and in fact about any erections whatever, and about unlawful ceremonies, or illicit mysteries.
