As far as the BSA goes, it should be noted that while the YMCA had a big hand in it’s early development, it was also given a boost in it’s early history by the Mormon Church, a non-Christian organization. The BSA’s acceptance of non-Christians goes back to it’s very beginning.
The fact that the highest award is known as Kings/Queens I have scouted with Mormons for over thirty years. Most Mormons would strongly disagree with you You are aware the the King/Queen of England
is the head of the Church of England.
Scout Award, this would imply that it is(was) a Christian Organization.
as they believe that they are Christians.
Given that I’m an Episcopalian I’m quite aware of the role of the British Sovereign in the Church. But the Sovereign is at least the titular head of a number of institutions there. That does not define Scouting’s identity as being attached to any of them.
I’m aware that most Mormons consider themselves Christians. However, if you research the matter you’ll find that no Christian denomination considers them Christian. There are a number of doctrinal differences between the LDS and Christianity that are quite central to both. It reaches the point that while a convert from one Christian denomination is considered by their new denomination to have been validly baptized and to be considered as having been a Christian prior to conversion. However, if a Mormon converts to a Christian denomination their baptism is not considered valid, they are not considered to have been Christian prior to conversion and they have to be baptized.
I do not know whether or not you are a Christian. If you are, I propose that you contact your national office (or look on their website) and see what they have to say on the matter.
