Rudolf Bultmann is best known for form criticism, a documented method of tracing the New Testament gospels back through the individual oral units, a healing story, a parable, a controversy dialogue, that circulated separately in early Christian preaching and teaching before an evangelist ever wove them into a continuous written narrative. That approach treats the written gospel as a later editorial assembly of pre-existing smaller units rather than as a single author's continuous eyewitness composition, a documented distinction in method from readings that took the finished narrative sequence itself as the primary object of historical inquiry.
As a professor at Marburg for most of his career, Bultmann applied that method within the wider Neo-Orthodox reaction against nineteenth century liberal Protestantism, a documented alignment on the movement's reassertion of the New Testament's theological seriousness even as his own critical method toward the text's composition history remained sharper than that of many Neo-Orthodox contemporaries content to treat the gospels' final form as theologically sufficient on its own. Identifying the oral forms behind a written passage, on his account, was a documented precondition for understanding what the earliest Christian communities actually believed and preached before any single gospel had been composed.
That a scholar could reconstruct the individual sermons, healing stories and controversy dialogues circulating in early Christian communities by working backward from the finished gospel text they were later assembled into marks Bultmann's form criticism as a documented case where a text's prehistory, not merely its final written shape, became the primary object of New Testament scholarship.
