Gibbon's subversive and iconoclastic description of the rise of Christianity inspired outrage upon publication, and remains one of the most eloquent and damning indictments of the delusory nature of faith.

The Progress of the Christian Religion, and the Sentiments, Manners,
Numbers, and Condition, of the primitive Christians

A candid but rational inquiry into the progress and establishment of Christianity, may be considered as a very essential part of the history of the Roman empire. While that great body was invaded by open violence, or undermined by slow decay, a pure and humble religion gently insinuated itself into the minds of men, grew up in silence and obscurity, derived new vigour from opposition, and finally erected the triumphant banner of the cross on the ruins of the Capitol. Nor was the influence of Christianity confined to the period or to the limits of the Roman empire. After a revolution of thirteen or fourteen centuries, that religion is still professed by the nations of Europe, the most distinguished portion of human kind in arts and learning as well as in arms. By the industry and zeal of the Europeans, it has been widely diffused to the most distant shores of Asia and Africa; and by the means of their colonies has been firmly established from Canada to Chili, in a world unknown to the ancients.

But this inquiry, however useful or entertaining, is attended with two peculiar difficulties. The scanty and suspicious materials of ecclesiastical history seldom enable us to dispel the dark cloud that hangs over the first age of the church. The great law of impartiality too often obliges us to reveal the imperfections of the uninspired teachers and believers of the gospel; and, to a careless observer, their faults may seem to cast a shade on the faith which they professed. But the scandal of the pious Christian, and the fallacious triumph of the Infidel, should cease as soon as they recollect not only by whom, but likewise to whom, the Divine Revelation was given.
