The reflections, Madam, which I have already offered you in these letters ought, I conceive, to have sufficed to undeceive you, in a great measure, of the lugubrious and afflicting notions with which you have been inspired by religious prejudices. However, to fulfil the task which you have imposed on me, and to assist you in freeing yourself from the unfavorable ideas you may have imbibed from a system replete with irrelevancies and contradictions, I shall continue to examine the strange mysteries with which Christianity is garnished. They are founded on ideas so odd and so contrary to reason, that if from infancy we had not been familiarized with them, we should blush at our species in having for one instant believed and adopted them. The Christians, scarcely content with the crowd of enigmas with which the books of the Jews are filled, have besides fancied they must add to them a great many incomprehensible mysteries, for which they have the most profound veneration. Their impenetrable obscurity appears to be a sufficient motive among them for adding these. Their priests, encouraged by their credulity, which nothing can outdo, seem to be studious to multiply the articles of their faith, and the number of inconceivable objects which they have said must be received with submission, and adored even if not understood. The first of these mysteries is the _Trinity_, which supposes that one God, self-existent, who is a pure spirit, is, nevertheless, composed of three Divinities, which have obtained the names of _persons_. These three Gods, who are designated under the respective names of the _Father_, the _Son_, and the _Holy Ghost_, are, nevertheless, but one God only, These three persons are equal in power, in wisdom, in perfections; yet the second is subordinate to the first, in consequence of which he was compelled to become a man, and be the victim of the wrath of his Father. This is what the priests call the mystery of the _incarnation_. Notwithstanding his innocence, his perfection, his purity, the Son of God became the object of the vengeance of a just God, who is the same as the Son in question, but who would not consent to appease himself but by the death of his own Son, who is a portion of himself. The Son of God, not content with becoming man, died without having sinned, for the salvation of men who had sinned. God preferred to the punishment of imperfect beings, whom he did not choose to amend, the punishment of his only Son, full of divine perfections. The death of God became necessary to reclaim the human kind from the slavery of Satan, who without that would not have quitted his prey, and who has been found sufficiently powerful against the Omnipotent to oblige him to sacrifice his Son. This is what the priests designate by the name of the mystery of _redemption_.
