Here's something to consider. The Federalist Papers were a series of 'op-ed' pieces written with the intention of explaining what the Constitution was designed to do. Yet, The Federalist Papers make no reference to Jesus, Christianity, or the Bible being the source or the guiding spirit of the Constitution, or our nation.
One more thing. If we were really a Christian nation, why is it that so many modern Christians shun the weak and want to punish the poor?
