I'd be willing to bet that most of these people in these assemblies have no idea what amillennialism actually is..
I'd also be willing to bet that if they did understand amillennialism.. Then perhaps 80-90% would abandon it.
The multitudes are simply added because of the doctrine of these self proclaimed infallible assemblies.. Which they have nothing to do with.
That seems like little nothing more than a hand-waving dismissal--"They can't
really believe these things, after all, they belong to
those churches."
To emphasize this further..
The clergy in these assemblies may be deceived into believing that they're infallible and therefore believe themselves to be incapable of failing at any doctrine.. although that has nothing to do with the laity as they're called..
In most cases I would assume that they (the laity) are simply ignorant of what amillennialism truly means.
IMO there's a difference between deception and ignorance.. but the point is that the multitudes which these assemblies represent, cannot be attributed to embracing the doctrine itself.
If any of that makes sense...
None of the groups I've mentioned have clergy that claim infallibility. The only one that comes even remotely close is Roman Catholicism with its doctrine of Papal Infallibility--but even that is only applicable matters where the Roman pontiff speaks ex cathedra; which has as far as I know happened a total of twice since the dogma was defined in the mid 19th century. Thus, not even the Pope is blanketly infallible even by Roman Catholic standards.
I think the only demonstration of ignorance here is your own concerning the various and many church bodies that make up Christendom and a need to dismiss the majority of your Christian brethren as empty-minded sheeple.
We either get to play by the OP's number crunching rules or we don't. If we are playing that game, Amillennialism is the clear victor.
Though I would agree with the OP's closing dismissal statement that a majority does not determine truth.
Truth is not determined by numbers, but if we are going to count numbers, then the numbers belong to the Amillennialist position.
So in the end, perhaps playing the numbers game isn't a prudent route to go in order to advance the Millennialist cause; and instead one should find a better argument to advance Millennialist ideas--demonstrate that Millennialism is true and right by its own merits.
But what nobody here gets to do is play the "Majority wins" card, and then when shown they are the clear minority dismiss the whole thing with a "Well, you all don't even really know what you're talking about anyway."
Y'all made your bed, now sleep in it.
