Why the "There are so many interpretations of the Bible" claim is confused

[Delicate]

My bad, I thought I posted the link before, where that quote was sourced.

Notice, if you will, the title of the article.  "Why does the salvation army not baptise or hold communion".  Hmn, sounds definitive........  It's just not something that they do, and they simply don't agree with others positions concerning grace.  You'll need to come to terms with this, they have.

That's very interesting, thanks.

It does look like it's a doctrinal issue, not a practical issue. So you got that part right.
It is a core issue, not a peripheral issue. That part is right too.

But there are some things missing from it too. 

For one, it's a single denomination. Compared to other denominations that affirm water baptism, it's a drop in the ocean. It simply won't do to predicate "soooooo muchhhh doctrinal divergence, bro" on 1 out of 33,000 denominations. There it lets the atheists down.
As well, it freely allows people to practice water baptism, and explicitly and repeatedly makes clear there's nothing wrong with people doing it. It doesn't say "baptism is wrong". So that's a mark against it too. 

The Salvation Army has never said it is wrong to use sacraments, nor does it deny that other Christians receive grace from God through using them.

However, it should be stressed that Salvationists have never been in opposition to the sacraments. Indeed, when they take part in gatherings with Christians from other churches, Salvationists will often share in using the symbols of the Lord's Supper as a sign of fellowship. Furthermore, Salvationists are not prevented from being baptised in other churches should they so desire.

But it's a good start. Can we show that it's widespread? What's the population of the Salvation Army members in the context of the larger Christian population?
