Then you don't know what is. Congress is only forbidden to pass a *law* about
religion. Even in this case, Congress didn't pass any law stating that the
phrase "In God We Trust" be placed on our money.


Sure they did. One instance amont many is the 1865 law "An Act to
authorize the Coinage of Three-Cent pieces, and for other Purposes."
This includes the following...

"And be it further enacted, That, in addition to the devices and legends
upon the gold, silver, and other coines [sic] of the United States, it
shall be lawful for the director of the mint, with the approval of the
Secretary of the Treasury, to cause the motto 'In God We Trust' to be
placed upon such coins hereafter to be issued as shall admit of such
legend thereon."
