No they didn't, they couldn't of by definiton. It's a logical inconsistency. You can't have your cake and eat it too.
Either the scriptures are perfect and only a perfect word of god is reliable,
Or the scriptures are not perfect and an imperfect word of god is still useful.
Only the second option makes sense if you believe humans are corrupt, as a corrupt human can't even register seeing the words, much less organizing them into thoughts, without corrupting the perfection. This happens then both when they were first written and when you read it yourself, as well as every single translation between. :yes:
