One underlying premise of this blog is that what is defined as “narcissism” in the secular world of psychology is equivalent to what is called “insolent pride” in the Bible. The basis for making this assertion is the substantial, but not necessarily 1:1, overlap of traits.
As Narcissistic Personality Disorder is still being researched in the formal field of psychology, and is only generally defined in the world of pop psychology, it does not have a clear, official definition (see here). Therefore, it stands to reason that there cannot be a complete 1:1 match between the terms “narcissism” and “insolent pride”, when one of the terms is not precisely defined. But, there is enough overlap of traits that we can use the term “narcissism” as an approximation for “insolent pride”.
The reason we are even using the term “narcissism” is that many people who are searching for answers on how to deal with these troublesome people will likely search using the term “narcissism”, as that is the term with which they are most familiar. But the most precise and real answers will come from the Biblical understanding of “insolent pride”. That is why we are using the terms synonymously, even though there is not a precise match-up between terms.
