The epistle is not written in the same form as the other biblical epistles, as it lacks an
epistolary opening or conclusion. The epistle is written in a simple style, without syntactical flourishes, In contrast to the linear style used in the
Pauline epistles, biblical scholar
Ernest DeWitt Burton suggests that John's thought "moves in circles", forming a slowly advancing sequence of thought. This is similar to the parallel structure of
Hebrew poetry, in which the second verse of a couplet often carries the same meaning as the first, although in this epistle the frequent recapitulations of already expressed ideas serve also to add to what has previously been said. In summary, the epistle may be said to exhibit a
paraenetic style which is "marked by personal appeal, contrasts of right and wrong, true and false, and an occasional rhetorical question". This affectionate
diminutive appears seven times in the letter, once as "my little children" (), and the phrase also appears in
John 13:33.
Paul also uses the phrase "my little children" when addressing the Galatian churches in
Galatians 4. Some scholars have proposed the idea that the epistle is really John's commentary on a selection of traditional parallel couplets. While this theory, first propounded by
Ernst von Dobschütz and
Rudolf Bultmann, is not universally accepted, Amos Wilder writes that, "It is at least clear that there are considerable and sometimes continuous elements in the epistle whose style distinguishes them from that of the author both with respect to poetic structure and syntactic usage." ==Authorship==
