From the period when the intimations were first published in the Protestant Vindicator, that a Nun had escaped from one of the Convents in Canada, and that a narrative of the secrets of that prison-house for females was preparing for the press; attempts have occasionally been made to prejudice the public judgment, by fulsome eulogies of the Roman Priests and Nuns, as paragons of immaculate perfection; and also by infuriated denunciations and calumnies of all persons, who seriously believe that every human institution which directly violates the constitution of nature, and the express commands of God, must necessarily be immoral. The system of seclusion and celibacy adopted in Convents is altogether unnatural, and subverts all the appointments of Jehovah in reference to the duties and usefulness of man; while the impenetrable secrecy, which is the cement of the gloomy superstructure, not only extirpates every incentive to active virtue, but unavoidably opens the flood-gates of wickedness, without restraint or remorse, because it secures entire impunity. Since the publication of the "Awful Disclosures," much solicitude has been felt for the result of the exhibitions which they present us: but it is most remarkable, that the incredulity is confined almost exclusively to Protestants, or at least, to those who pretend not to be Papists. The Roman Priests are too crafty to engage directly in any controversy respecting the credibility of Maria Monk's narrative. As long as they can induce the Roman Catholics privately to deny the statements, and to vilify Christians as the inventors of falsehoods concerning "the Holy Church and the Holy Priests!" so long will they laugh at the censures of the Protestants; and as long as they can influence the Editors of political papers vociferously to deny evangelical truth, and to decry every attempt to discover the secrets of the Romish priestcraft as false and uncharitable, so long will the Jesuits ridicule and despise that incredulity which is at once so blinding, deceitful, and dangerous. The volume entitled "Awful Disclosures by Maria Monk," has been assailed by two classes of Objectors. Some persons affirm that they cannot, and that they will not believe her narrative, because it is so improbable. Who is to judge of the standard of improbabilities? Assuredly not they who are ignorant of the whole subject to which those improbabilities advert. Now it is certain, that persons who are acquainted with Popery, are generally convinced, and readily agree, that Maria Monk's narrative, is very much assimilated to the abstract view which a sound judgment, enlightened by the Holy Scriptures, would form of that antichristian system, as predicted by the prophet Daniel, and the apostles, Peter, Paul, and John.
