A movement that developed in the late 19th and early 20th centuries among some conservative Christians who held certain beliefs, including the inerrancy of the Bible, the virgin birth, Jesus’ substitutionary atonement for the sins of all who believe in him, etc. Some non-Christians have a more generic concept of Fundamentalist Christianity, and apply the term to any who believe that their form of Christianity is the only true way to God. Extremist Fundamentalist Christians may disagree with other Fundamentalist Christians over relatively minor issues and some have negative views of any who are not a part of their particular Christian denomination.
