As the title says; How many times has The Bible/Quran/Torah been changed? Whether because of it being written in different languages and the translation causes some alterations, or different dogmas and beliefs causing suppression and oppression of the of the text.
What changes do we know for certain has been made, added or otherwise altered these sacred religious text?
I’m happy to discuss this in regards to the Quran, but it may be worth asking these as separate questions. I’m not sure what kind of linkage you’re expecting between the three texts, but I’m not sure that the formation of the text of the Quran has relevance to the other two texts or vice versa.
Edit: If you have such a linkage in mind perhaps you can elaborate on what it might be and I could try to touch on that?
