Was just reading a little about Thomas Paine and his ideas on the authenticity of the bible and organized religion. His writings triggered a short-lived spike in deism (though his earlier writing Common Sense helped trigger the American revolution). I thought it was interesting to read his words from 230 years ago and how much they still apply to the religions of today. Some excerpts below.

His creed:

I believe in one God, and no more; and I hope for happiness beyond this life. I believe in the equality of man; and I believe that religious duties consist in doing justice, loving mercy, and endeavouring to make our fellow-creatures happy. But, lest it should be supposed that I believe many other things in addition to these, I shall, in the progress of this work, declare the things I do not believe, and my reasons for not believing them. I do not believe in the creed professed by the Jewish Church, by the Roman Church, by the Greek Church, by the Turkish Church, by the Protestant Church, nor by any church that I know of. My own mind is my own church. All national institutions of churches, whether Jewish, Christian or Turkish, appear to me no other than human inventions, set up to terrify and enslave mankind, and monopolize power and profit. I do not mean by this declaration to condemn those who believe otherwise; they have the same right to their belief as I have to mine. But it is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing, or in disbelieving; it consists in professing to believe what he does not believe.

On the bible:

My intention is to show that those books are spurious, and that Moses is not the author of them; and still further, that they were not written in the time of Moses, nor till several hundred years afterward; that they are no other than an attempted history of the life of Moses, and of the times in which he is said to have lived, and also of the times prior thereto, written by some very ignorant and stupid pretenders to authorship, several hundred years after the death of Moses, as men now write histories of things that happened, or are supposed to have happened, several hundred or several thousand years ago.

On the fall of man:

The Christian Mythologists, after having confined Satan in a pit, were obliged to let him out again to bring on the sequel of the fable. He is then introduced into the Garden of Eden, in the shape of a snake or a serpent, and in that shape he enters into familiar conversation with Eve, who is no way surprised to hear a snake talk; and the issue of this tête-à-tête is that he persuades her to eat an apple, and the eating of that apple damns all mankind. After giving Satan this triumph over the whole creation, one would have supposed that the Church Mythologists would have been kind enough to send him back again to the pit: or, if they had not done this, that they would have put a mountain upon him (for they say that their faith can remove a mountain), or have put him under a mountain, as the former mythologists had done, to prevent his getting again among the women and doing more mischief. But instead of this they leave him at large, without even obliging him to give his parole—the secret of which is that they could not do without him; and after being at the trouble of making him, they bribed him to stay. They promised him ALL the Jews, ALL the Turks by anticipation, nine-tenths of the world beside, and Mahomet into the bargain. After this, who can doubt the bountifulness of the Christian Mythology? Having thus made an insurrection and a battle in heaven, in which none of the combatants could be either killed or wounded—put Satan into the pit—let him out again—gave him a triumph over the whole creation—damned all mankind by the eating of an apple, these Christian Mythologists bring the two ends of their fable together. They represent this virtuous and amiable man, Jesus Christ, to be at once both God and Man, and also the Son of God, celestially begotten, on purpose to be sacrificed, because they say that Eve in her longing had eaten an apple.
