STILL TRYING TO MAKE SENSE OF IT

Many years ago, some told people not to read 1's religious books. Yet many were found preaching and teaching materials got from often-unpublished, such books. This has repeated since 2005 when 1 hears commands to mind 1's religious business. Today, it seems not 1 will touch at least A Letter directed to Christians yet such piratical teachings not only continue but who were recently  teaching such materials in Church schools( low to highest)?
