Such as?
The founders refused to place anyone religion before another
Didn't read the links?
the even went so far as to explicitly forbid the government from doing it!
The Feds, not the states. This is Jeffersons model for government.
"The way to have safe government is not to trust it all to the one, but to divide it among the many, distributing to everyone exactly the functions in which he is competent....To let the National Government be entrusted with the defense of the nation, and its foreign and federal relations..... The State Governments with the Civil Rights, Laws, Police and administration of what concerns the State generally. The Counties with the local concerns, and each ward direct the interests within itself. It is by dividing and subdividing these Republics from the great national one down through all its subordinations until it ends in the administration of everyman's farm by himself, by placing under everyone what his own eye may superintend, that all will be done for the best." Thomas Jefferson
Tax advantages - SS survivors benefits - and many more, mostly financial items.
If you read the rest of what I said, you would realize that I did read you links - and find them ENCOURAGING religion, but not any one specific one (Christianity is a combination of several "flavours"). I saw NO requirements for anyone to observe any pariticular belief.
Yes, the founders only applied to the constitution to the federal government - would that we did that today! How many STATE constitutions allowed the state government to restrict/dictate religious practices?
For the record, so you don't argue down that road - I am a firm believer in the sovereignty of the people themselves and that each and every level of government derives its powers from the consent of us - since you seem to favor the same argument, we need not debate the point.
