Like the other Founding Fathers, Jefferson was considered a Deist, subscribing to a liberal religious strand that values reason over revelation and rejects traditional Christian doctrines, including the Virgin Birth, original sin and the resurrection of Jesus.
Actually, the other Founding Fathers are NOT considered deists, as John Fea of Messiah College explains here.
"The founding fathers were deists."
I have probably heard this statement affirmed just as much as I have heard claims that the founders were Christians. It is one of the many pieces of ammunition used by the opponents of the idea that the United States was founded as a Christian nation. If the founders were indeed deists, the argument goes, they could not have founded a uniquely Christian republic.
In actuality, there were a lot more founders who were Christians than deists. And of those founders who did not identify with the doctrines of historic Christianity, few could be called deists.So it goes. Unfortunately, those who minimize our religious heritage are in control of quangos like PBS, and of course the lion's share of academia, and for the large part control the general public perception of history. Thus amateurs such as David Barton arise in response, whose most trivial of errors and inconsistencies are hunted down with the persistence of Javert.
For those at home without scorecards, that's the gist of it.
