A few little snippets from the Boy Scouts, for anyone who has any doubts about it's spiritual requirements. These are from memory so, please, be merciful. I only had to say them about 10 thousand times.
The Scout Oath
--------------------
On my honor I will do my best
to do my duty to God and my country
To obey the Scout Law
To help other people at all times
To keep myself physically strong
mentally awake
and morally straight
The Scout Law
----------------------------
A Scout Is..
Trustworthy, Loyal, Helpful, Friendly, Courteous, Kind, Obedient, Cheerful, Thrifty, Brave, Clean, and Reverent
Now, Scouting does not say that you must be Christian. It doesn't 'specifically' say you cannot be an Atheist, but the implication is there nonetheless.
