Something very different from what the Catholic Church teaches. If your goal is to support efficient aid to the needy, then so what?
NC Baptist Men's Disaster Relief doesn't have Catholic beliefs about the Sacraments, either ... but they're the very best local disaster relief group. If I want to help victims of a natural disaster, that's where my money goes.
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.
