Before his arrest and imprisonment in France, knowing that he would probably be arrested and executed, following in the tradition of 
early 18th-century British Deism Paine wrote the first part of 
The Age of Reason (1793–1794). Paine's religious views as expressed in 
The Age of Reason caused quite a stir in religious society, effectively splitting the religious groups into two major factions: those who wanted church disestablishment, and the Christians who wanted Christianity to continue having a strong social influence.

About his own religious beliefs, Paine wrote in 
The Age of Reason:
I believe in 
one God, and no more; and I hope for happiness beyond this life.
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.
Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and tortuous executions, the unrelenting vindictiveness with which more than half the Bible is filled, it would be more consistent that we call it the word of a demon than the word of God. It is a history of wickedness that has served to corrupt and brutalize mankind; and, for my part, I sincerely detest it, as I detest everything that is cruel.
