I'd say:
Exclusive use of King James Version.
Rejection of all Calvinism.
Abstaining from all alcoholic beverages.
Separation from other denominations.
Aggressive "soul winning".
Dispensational and pre-Trib rapture teaching.
When I was one we abstained from movies in general, rock and roll music, and officially, you weren't supposed to even eat at an establishment that served alcohol, even if you didn't buy any. There was also the obsession with clothing and hair but that was the '70's and early '80's. That said, the congregation was loving, welcoming to new people, and all the prohibitions were done in a good hearted manner with even some humor and always with love. We left because we moved out of the area.
Oh yeah. They had the best pot luck dinners ever, anywhere.
Forgive me, but several in this list of doctrines ignores the historical origin of the movement. It started out with different denominations and minor doctrines, but all took a stand against liberalism (separatistic) and for the Word of God.
"Exclusive use of King James Version." Nope. To this day there are fundamentalist churches that do not use the KJV. For example, in Japan where I was for 33 years we did not have the KJV (it's English, you know
) or even a TR based Japanese NT.
"Rejection of all Calvinism." Not strictly true, since Presbyterians were among the early Fundamentalists (Machen, etc.), and even today the Bible Presbyterians (started by Carl McIntyre) are fundamentalists.
"Abstaining from all alcoholic beverages." Mostly true.
"Separation from other denominations." No, but separation from liberalism. Sometimes the early fundamentalists stayed in their denominations, fighting the liberalism from within.
Aggressive soul winning." I agree.
"Dispensational and pre-Trib rapture teaching." Not always. Some of the leading fundamentalists of the past were not Dispensationalists. John R. Rice is one example.
