An accurate definition of Fundamentalism was given by the World Congress of Fundamentalists, which met in 1976 in Usher Hall, Edinburgh, Scotland:

A Fundamentalist is a born-again believer in the Lord Jesus Christ who--

1.Maintains an immovable allegiance to the inerrant, infallible, and verbally inspired Bible.
2.Believes that whatever the Bible says is so.
3.Judges all things by the Bible and is judged only by the Bible.
4.Affirms the foundational truths of the historic Christian Faith: The doctrine of the Trinity; the incarnation, virgin birth, substitutionary atonement, bodily resurrection and glorious ascension, and Second Coming of the Lord Jesus Christ; the new birth through regeneration by the Holy Spirit; the resurrection of the saints to life eternal; the resurrection of the ungodly to final judgment and eternal death; the fellowship of the saints, who are the body of Christ.
5.Practices fidelity to that Faith and endeavors to preach it to every creature.
6.Exposes and separates from all ecclesiastical denial of that Faith, compromise with error, and apostasy from the Truth.
7.Earnestly contends for the Faith once delivered.

The World Congress of Fundamentalists summarized their definition in this way: "Fundamentalism is militant orthodoxy set on fire with soulwinning zeal."
