John, I was referring to the start of Methodism under the Wesley brothers. They were the first "fundamentalists" in that their methods were established based upon the fundamental truths they saw in scripture.
It's a misconception that fundamentalism only consists of adherence to fundamental doctrines. If there is no form of ecclesiastical separatism, there is no fundamentalism in the genuine sense. Billy Graham was a fundamentalist early in his career, but from 1957 he refused to be called one, though he adhered to the same doctrines as the fundamentalists.
Ultimately, however, such a focus on rules leads to legalism and then makes a hard shift toward liberalism.
I'm puzzled. Are you equating the fundamental doctrines of the "faith which was once delivered unto the saints" with simple rules?
My observation is that any form of legalism will result in one of two things. Either the person (following legalism) will become very prideful in how well they think they are doing, or they become very depressed in how poorly they think they are doing. When a person sees that they cannot live up to such "holiness" standards, they often give up on Christianity or they go into liberalism to avoid their feelings of despair.
I do agree with your assessment, as long as you are defining legalism correctly according to its theological meaning (and many do not) and not with some cultural construct.
Here is a Baptist theologian's definition: "Legalism is a slavish following of the laws in the belief that one thereby earns merit; it also entails a refusal to go beyond the formal or literal requirements of the law” (Millard Erickson,
Christian Theology, 2nd ed., p. 990).
Some think that legalism is simple adherence to rules, and therefore all fundamentalists are somehow legalists, but that's not accurate. There is a strain of fundamentalism that thinks that sanctification involves the keeping of rules, but I'm not from that group. Most fundamentalists, following the Keswick tradition, realize that sanctification must be based on faith, not works.
My comments toward fundamentalists and evangelicals is purely anecdotal. Both, however, tend to be synergists in my experience which often tends toward legalism in my observation.
Synergist theology was not actually any part of original fundamentalism. I refer you to the Presbyterian fundamentalists such as J. Gresham Machen, Carl McIntyre, B. B. Warfield, and Francis Schaeffer (who later became a New Evangelical but leaned back towards fundamentalism in his book,
The Great Evangelical Disaster). Again, the Stewart brothers, who financed the series of books known as "The Fundamentals," were Presbyterians.
And believe it or not, one of the leading independent Baptist seminaries is 4 point Calvinist, Detroit Baptist Theological Seminary. (Went there for a "Bible Faculty Summit" last year.)
From reading your comments, you are a professor so I expect and accept that you will view this topic from an academic perspective. I can only speak from experiential observation.
I'm fortunate to have both the experiential and the academic perspectives, having been raised independent Baptist.
