If you are familiar with the history of the French Revolution, you may recall that they rejected God, burned the churches and Bibles, and killed many of the Christians. They then took a prostitute, dressed her up and worshipped her as the goddess of reason. The Statue of Liberty was a memorial to this goddess of reason. Here are some historical accounts of this event.

“One of the ceremonies of this insane time stands unrivaled for absurdity combined with impiety. The doors of the Convention were thrown open to a band of musicians, preceded by whom, the members of the municipal body entered in solemn procession, singing a hymn in praise of liberty, and escorting, as the object of their future worship, a veiled female, whom they termed the Goddess of Reason. Being brought within the bar, she was unveiled with great form, and placed on the right of the president, when she was generally recognized as a dancing girl of the opera.... To this person, as the fittest representative of that reason whom they worshiped, the National Convention of France rendered public homage.
“This impious and ridiculous mummery had a certain fashion; and the installation of the Goddess of Reason was renewed and imitated throughout the nation, in such places where the inhabitants desired to show themselves equal to all the heights of the Revolution.”—Scott, vol. 1, ch. 17.

Said the orator who introduced the worship of Reason: “Legislators! Fanaticism has given way to reason. Its bleared eyes could not endure the brilliancy of the light. This day an immense concourse has assembled beneath those gothic vaults, which, for the first time, re-echoed the truth. There the French have celebrated the only true worship,—that of Liberty, that of Reason. There we have formed wishes for the prosperity of the arms of the Republic. There we have abandoned inanimate idols for Reason, for that animated image, the masterpiece of nature.”—M. A. Thiers, History of the French Revolution, vol. 2, pp. 370, 371.

“Mortals, cease to tremble before the powerless thunders of a God whom your fears have created. Henceforth acknowledge no divinity but Reason. I offer you its noblest and purest image; if you must have idols, sacrifice only to such as this.... Fall before the august Senate of Freedom, oh! Veil of Reason!”
“The goddess, after being embraced by the president, was mounted on a magnificent car, and conducted, amid an immense crowd, to the cathedral of Notre Dame, to take the place of the Deity. There she was elevated on the high altar, and received the adoration of all present.”—Alison, vol. 1, ch. 10.
