I already asked this question on the writing forum, but I suppose the subject matter is better suited here.
Once again, I am writing a commentary on the book of Galatians, while employing a socio-rhetorical analysis.
The writer introduces himself as an Apostle, establishing his authority, and concludes with reprimanding "false apostles".
The ideas are juxtaposed, being separated by a large number of juxtaposing words, concepts, and allusions. (Flesh and spirit, life and death, Hebrew and Greek, male and female etc.)
I am attempting establish that the document as a whole begins and ends with opposing concepts that are only separated by the repeated use of the same rhetorical devices applied to the beginning and ending of the letter.
In doing this, the writer has persuaded the reader to accept the introductory and concluding statements, which are quite contrary to one another, by using similarly contrasting phrases between the two opposing ideas.
I'm hoping there is a definitive term to apply to this technique.
I'm trying to be as clear as possible. I would like to identify the arrangement as a whole. The construction appears to be what I can only define as an "expanded juxtaposition", at least, abstractly speaking.
I've never seen such a mode of persuasion used in any other literature. Is there a technical term for this type of format, or have I stumbled across something that needs defining?
