Well, that is the 1st Amendment. And Congress is the only institution that can pass a law to establish a religion, but they are restricted from doing so. Private and pseudo-private institutions can not pass a law that says you and I have to go to the Glory Bound Baptist Church every Sunday.

[the invisib1e hand]

and pseudo-private institutions

can and do make rules that congress is forbidden to.

Pardon that I didn't distinguish between such rules and "laws." It will be noted that, often, the former are more effective than the latter.

Merry Christmas.
