Are you saying he posted scripture that didn't exist? Who is this? I actually don't believe that. Many people are surprisingly good with their scripture and would immediately spot someone quoting non-existent scripture.
Unless maybe he was quoting some non-canon like Mormon books. Very common for "Christian" influencers to be LDS.
i can believe this. many "experts" are consistent bullshitters, and it helps them to look more like experts.
this is not always intentional either, and there is a lot of social pressure to do it.
have you ever read a popular article about something you have expert knowledge in? the general standard for accuracy and quality in public discourse is mindblowingly low.
They said classical education, so that would be Roman and Greek books.
