Premillennialism is heresy according to the the Council of Ephesus 431.
The way I see things, the church-at-large was already going apostate beginning in the second century, and true believers began to be outnumbered by false brethren who came in unawares and took over.
What started out pure in doctrine and practice very quickly, by the time of John's writing Revelation, began to unravel, from my perspective.
That's why I don't generally recognize the councils of men, Dave.
Because many of them don't speak for me, and many of them I think were mainly populated by those who thought they were saved, but really weren't.
The Council of Trent, for example, said nothing that I need to concern myself with, and its edicts do not bind me.
Neither did Vatican I, Vatican II, nor any of the other meetings of the visible church that occurred during the time of the "Early Church Fathers"...which were the forerunners of what we now call the RCC.
In fact, almost everything the Roman Catholic Church taught or now teaches,
including a-millennialism and "Molinism", I find to be in error.
While I agree with some of what they teach about Christ, I only do so because they are in agreement with Scripture...
Which is, more often than not, the exception to the rule in my estimation.
Now, some articles written up and agreed to by men I do find myself in agreement with.
For example:
I agree with the London Baptist Confessions of 1644/46 and 1689, but not all the ones that came after them.
I agree with the Canons of Dordt...
But that does not mean that I go along with
everything that John Calvin or John Knox taught or may have taught.
I agree with a great many things that John Wesley had to say...
But not his view of how salvation is accomplished by God.
I also agree with many things that John R. Rice had to say...
But again, not his view of salvation.
Finally, I'm "pre-millennial" and "post-Tribulational"...
and that is why I'm not "Reformed", in the traditional sense.
Good evening to you.
