According to the secular source Wikipedia
“The New Testament has been preserved in more manuscripts than any other ancient work, having over 5,800 complete or fragmented Greek manuscripts, 10,000 Latin manuscripts and 9,300 manuscripts in various other ancient languages including Syriac, Slavic, Gothic, Ethiopic, Coptic and Armenian.
There are more manuscripts that preserve the New Testament than there are for any other ancient writing, the exact form of the text preserved in later manuscripts may not be identical to the form of the text as it existed in antiquity but are agreed by most scholars to be 99.5% identical in content, with the differing .5% attributed to minor variations such as spelling. These variations are not seen to affect the meaning or interpretation of NT scriptures and are usually given reference to as in-page footnotes in most of today’s bibles.
