In this case, which involves the US Constitution, it doesn't matter what Congress says, but it matters a great deal what SCOTUS says.
And Scotus says that
(a) EVERYONE has the freedom to choose their own views about religion, so that includes Jews, Muslims, Buddhists, Hindus, Satanists, Native religions, atheists, every color of the religious spectrum, and
(b) public money, hence public schools and their staff, may not, indeed must not, root for any particular religion or view of religious belief.
Got it?
Nope, do you Got it.
Congress Passed this Resolution
"The Congress of the United States recommends and approved the Holy Bible for use in all schools"
United States Congress 1782.
Now in case you don't know, The Tradition of the forefathers, was the bible, so it would be evidence what religion that Congress would be in reference to, seeing how Congress Recommended and approved the Holy Bible.
Now why would Congress out of all the religious books there is, only signify only one book out of them all, The Holy Bible. Which is a Christian holy book. To be recommended for use in all schools.
If, and that's a big If, if Congress as you say, ment all other religions, Then why is the Christian Bible the only book that Congress signified out of them all, For the use in all schools.
Now notice Congress did say the
( Holy Bible ) so what other book is called
The ( Holy Bible ) other than the Christian
Holy Bible.
Every Bible right on the very front cover has printed ( Holy Bible ) signifying it's a Christian Holy Bible.
Maybe before you go saying what about all these other religions, maybe you can show as to where the founding fathers said anything about all those other religions.
Seeing how before a law can be pass by Congress it first has go to the President and the Senate first, before Congress can put it into law.
Therefore the President and Congress and the Senate all agreed that the
Christian Holy Bible approved for use in all schools.
Got it.
