@alexsonofmatthew,
*Sigh*, no wonder people are confused:
First of all, the distinction between «progressive» and «traditional adventists” is first and foremost a quirk here at christianforums! Keep in mind that we're talking about differences within the same denomination here. Adventists will rarely apply any of these terms to themselves. On this forum the only difference between the two subforums is that it's okay to argue against the so-called "28 fundamental beliefs" in the progressive forum, but not in the traditional one.
It's true some adventists are progressives in the way that
@EastCoastRemnant described, however, I would say that they are a minority. Adventists with liberal attitudes aren't necessarily “progressive” in this sense, and often very conservative people are progressives too.
As for “traditional adventists”, well, this isn't really a common term for
any division within the Adventist church. On this forum the term is defined as those who believe in the 28 fundamental beliefs, which in reality could be conservatives, moderates
and liberals. However, in practice this distinction (progressive/traditional) has become a way of keeping liberals and conservatives apart from each other here on this forum. If you think this is confusing, then you're right!
Over to the actual theological division in the adventist Church... Generally speaking you have liberals and conservatives, and then you have certain subgroups that belong to the fringes. For instance, on the ultra-liberal side you have people believing in evolution. On the ultra-fundamentalist side you have people denying the trinity and claiming the Church is in apostasy.
However, most adventists belong to the mainstream, they might come in a liberal or conservative flavour, but they generally believe in the 28 fundamental beliefs, in creation and in the trinity.
tl;dr: The distinction between "progressive" and "traditional" adventists is used for convenience here on this forum, and shouldn't be understood as an accurate descriptive of the actual theological divisions within the adventist Church.
