Task: Question Generation
Input (English): Further claims were made that the Roman Catholic Church derives its doctrine from the Islamic teaching. In volume 5 of his Decline and Fall of the Roman Empire, published in 1788, Edward Gibbon wrote: "The Latin Church has not disdained to borrow from the Koran the immaculate conception of his virgin mother." That he was speaking of her immaculate conception by her mother, not of her own virginal conception of Jesus, is shown by his footnote: "In the xiith century the immaculate conception was condemned by St. Bernard as a presumptuous novelty." In the aftermath of the definition of the dogma in 1854, this charge was repeated: "Strange as it may appear, that the doctrine which the church of Rome has promulgated, with so much pomp and ceremony, 'for the destruction of all heresies, and the confirmation of the faith of her adherents', should have its origin in the Mohametan Bible; yet the testimony of such authorities as Gibbon, and Sale, and Forster, and Gagnier, and Maracci, leave no doubt as to the marvellous fact."
Output (English): Where does the author state that the Roman Catholic Church received her facts and confirmations ?
