Beginning in the 20th century, however, critical scholars like Heinrich Julius Holtzmann and C. H. Dodd identified the Gospel of John and 1 John as works of different authors. Certain linguistic features of the two texts support this view. For instance, 1 John often uses a demonstrative pronoun at the beginning of a sentence, then a particle or conjunction, followed by an explanation or definition of the demonstrative at the end of the sentence—a stylistic technique which is not used in the gospel. The author of the epistle also "uses the conditional sentence in a variety of rhetorical figures which are unknown to the gospel". This indicates, at the very least, the linguistic characteristics changed over time. Today, following the work of J. Louis Martyn and Raymond Brown, the majority of scholars believe that John and 1 John were written by different members of the same community: the "Johannine Community".
