"Congress Shall Make No Law Respecting the Establishment of Religion"

That seems simple enough...so why is it that every few years or so we have to put up with nonsense like posted Ten Commandments, followed by the inevitable court challenges, followed by the eventual Supreme Court opinion, followed by rinse and repeat?

Any self-respecting religion--and any self-respecting religious individual--would want to keep their material OUT of government offices. Any religion demanding some sort of official imprimatur from the state seems to me to be acknowledging that it's too weak to make it on it's own. And, in particular, the Christian religion has a specific prohibition against such public displays:

Matthew 6:5-6: "And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men....when thou prayest, enter into thy closet and when thou has shut thy door, pray to thy Father which is in secret...."

Religions already receive perhaps the most generous "subsidy" even passed out by government--they are tax exempt.

To be fair, some religious organizations are on record as opposing the display of religious symbols on public property. Good for them. Too bad so many other religious groups, particulary Christian ones, apparently can't even read their Bibles. Hypocrites.
