Cute euphemism. No.

Sometimes people want to quote the Bible in AA. I've probably done it. That's kinda OK, maybe, because page 87 does indeed suggest that we can make use of what religious people have to offer. It's a bit naughty because of Traditions Six and Ten, not to mention One and Three, to a lesser extent.

What's not on is calling it 'the other Big Book' or, what's worse, 'the Bigger Book'.

The Bible is not AA Conference-Approved Literature. AA is not religious. The Bible does not trump the Big Book when it comes to alcoholism. It does not even cover alcoholism, at least not in any systematic way.

The biggest book we have in AA is the Big Book.

If you're gonna mention the Bible, say, 'The Bible' and take responsibility, rather than making it seem like an extension of the Big Book, or some secret volume under the table.

Ditto 'Jesus' and 'The Carpenter'.

Mention who you want, and be prepared to justify why it's not a Tradition breach. But nail your colours to the mast when doing so.
