I attended the Salvation Army CHURCH. The Coronel Samuel Logan Bringle, in 1906 suggested that since most of it;s adherents came from the saloon crowd, and booze parlors, that they abstained from all sipping of the cup. They thought by doing such they could avoid the conflict of which cup was right, the One Cuppers, or the mini cups, and the strong wine, vs, grape juice. For a while, the insttition of the Lords Supper and how it was served and how often served more to divide people than unite them.
The history of The Salvation Army as a Christian denomination as well as a service organization is extremely interesting.
Re the article, if a person wants to support only organizations that share his religious beliefs 100%, he can do that. However, the Catholic faith does not insist that he must.
