I don't think that fact disqualifies that distinction I made. For a point of common reference, as I know the term "fundamentalism" is used all over the place, like the term spirituality is. But I'm going with how it was first used as a modern term beginning in the late 1800's in America. It can be applied to other religions than just Christianity, but its origin of use was American Protestant religions of a particular anti-modernity bent. It is precisely why they are called funamentalists.
Here's a quick synopsis of what I'm looking at. From Wiki article on Fundamentalism:
Christian fundamentalism has been defined by
George Marsden as the demand for a strict adherence to certain theological doctrines, in reaction against
Modernist theology.
[12] The term was originally coined by its supporters to describe what they claimed were five specific classic theological beliefs of Christianity, and that developed into a
Christian fundamentalist movement within the Protestant community of the United States in the early part of the 20th century.
[13] Fundamentalism as a movement arose in the United States, starting among
conservative Presbyterian theologians at
Princeton Theological Seminary in the late 19th century. It soon spread to conservatives among the
Baptists and other denominations around 1910 to 1920. The movement's purpose was to reaffirm key theological tenets and defend them against the challenges of
liberal theology and
higher criticism.
[14]
The term "fundamentalism" has roots in the
Niagara Bible Conference (1878–1897), which defined those tenets it considered
fundamental to Christian belief. The term was prefigured by
The Fundamentals, a collection of twelve books on five subjects published in 1910 and funded by the brothers Milton and
Lyman Stewart, but coined by Curtis Lee Lawes, editor of
The Watchman-Examiner, who proposed in the wake of the 1920 pre-convention meeting of the Northern Baptist Convention (now the
American Baptist Churches USA) that those fighting for the fundamentals of the faith be called "fundamentalists."
[15] The Fundamentals came to represent a
Fundamentalist–Modernist Controversy that appeared late in the 19th century within some Protestant denominations in the United States, and continued in earnest through the 1920s. The first formulation of American fundamentalist beliefs traces to the Niagara Bible Conference and, in 1910, to the General Assembly of the Presbyterian Church, which distilled these into what became known as the
five fundamentals:
[16]
It did
not (yet) become associated with tenets such as
Young Earth creationism.
By the late 1910s, theological conservatives rallying around the five fundamentals came to be known as "fundamentalists". They reject the existence of commonalities with theologically related religious traditions, such as the grouping of Christianity, Islam, and Judaism into one Abrahamic family of religions.
[3] In contrast, Evangelical groups (such as the
Billy Graham Evangelistic Association), while they typically agree on the theology "fundamentals" as expressed in
The Fundamentals, are often willing to participate in events with religious groups who do not hold to the essential doctrines.
[17]
As such can be seen in the above, it is clear that fundamentalism is not the same as traditionalism. It is based upon a negative reaction to something. It's born out of "not-this". The definition of reactionary is "(of a person or a set of views) opposing political or social liberalization or reform." Traditionalism is not a reactionary thing at all. So it's quite distinctly different, even if it claims traditionalism as it's home. In reality, they are kind of its own thing as an offshoot of it.
