Thomas Paine wrote The Age of Reason in 1794. The Cult of Reason then banned the Catholic Mass in France.
That's the name of a pamphlet. It's timing does not frame the 17th Century Age of Reason (a.k.a., Age of Rationalism).
Furthermore, you have a false cause and effect. Paine wrote The Age of Reason after the French Revolution, being worried about its decay into immorality. It was first published AFTER the Reign of Terror was underway. In fact, Paine himself was imprisoned and almost executed during the Reign of Terror, so it is not likely he would write anything supportive of it.
