Qumran and the origins of Johannine language and symbolism - Elizabeth W. Mburu

This work sets out to demonstrate that the sectarian Qumran document The
Rule of the Community, provides linguistic clues which illuminate our
understanding of how the author of the Fourth Gospel used truth
terminology and expected it to be understood. It establishes that there
are significant linguistic similarities shared by these two corpora.
While these may be attributed to a development of the common tradition
shared by both, as well as the influence ideology, the semantic
continuity with the Rule of the Community makes it likely that the
author of the Fourth Gospel was familiar with the mode of thought
represented in the linguistic matrix of the Qumran literature and that
he followed this in articulating his ideas in certain parts of his
Gospel.
