Paradiastole

Paradiastole (from Greek παραδιαστολή from παρά "para" "next to, alongside", and διαστολή "diastole" "separation, distinction") is the reframing of a vice as a virtue, often with the use of euphemism, for example, "Yes, I know it does not work all the time, but that is what makes it interesting." It is often used ironically. 
In studies on classical antiquity, it has come to mean the repetition of disjunctive words in a list. Another example is referring to manual labour as a "workout". Perhaps the most familiar usage today comes from the software world: "It's not a bug; it's a feature!" (This is used both euphemistically and literally, as many features in software originated as bugs).
Biblical usage.
In biblical studies, paradiastole is a type of anaphora (the repetition of one word at the beginning of successive sentences). Paradiastole uses a few words—either, or, neither, not, and nor—used as disjunctions. A "dis"junction differs from a "con"junction because it separates things, whereas a conjunction joins them.
An example of this technique can be found in the Gospel of John, clarifying the meaning of τέκνα θεοῦ (God's children):
In this passage, οὐκ and οὐδὲ (here translated "not" and "nor") function as the disjunctions. The paradiastole emphasizes that those who believed (οἳ πιστεύοντες) and became "God's children" were not
"physically" ("of blood", etc.) born again, but "divinely."
The French Enlightenment writer Voltaire remarked sardonically: "This agglomeration which was called and which still calls itself the Holy Roman Empire was neither holy, nor Roman, nor an empire."
