This may sound retarded and like it doesn’t matter.
To be clear, right now, in the current year, the final product is basically the same. HOWEVER if you actually crack open the Nestle-Aland (current liberal text) and use the apparatus, you will see many cases where they’re straight up putting primary readings in the body that don’t exist in a single manuscript.
One day, someone is going to come along and “revolutionize” the field with yet another bogus miracle method for purifying the text, quite possibly using forgeries (which they already do in some cases) and little by little, they’re going to start chipping away at doctrines.
They’ve already commercialized the process. They tell you that you have to buy a new edition every few years, or you’ll never know what the Bible really says.
This is not how it works. The Bible does not change.
