The bible says drunkards will not inherit the kingdom. It says nothing about the occasional, social, over-drinker?
Good lord, you're dredging up more memories.
There was another elders school that got into this issue with agonizing detail. The instructor asked if someone was an alcoholic, could he be DF'ed?
In one of the rare opportunities to express opinions not pre-approved by "mother", some elders commented yes, others no.
The instructor said the answer was "no". The Bible condemns "drunkenness", not "alcoholism".
He then went on, again in excruciating detail, about how the Bible describes "drunkenness". IIRC, it was a bunch of stuff from Proverbs about "staggering around" and "eyes seeing strange things".
He said an alcoholic might not ever exhibit such symptoms, thus, strictly Biblically speaking, he would not be considered "drunk" and thus not subject to congregation discipline. Such a person wouldn't be "exemplary" and so couldn't be a pioneer, elder, MS, etc., but without that Biblical "evidence" of drunkenness, no judicial action was to be pursued.
The unspoken takeaway, of course, to the undoubted delight of a significantly high proportion of the attendees, was that if you can "hold your liquor" and not act stumblingly stupid while drunk, there was no problem.
