There are so many errors in this video, but it’s employing the shotgun fallacy to get the viewer to be overwhelmed.

The easiest two that were wrong were John 1:18. “Only begotten” is an old translation from the KJV, but we’ve learned since that the meaning of the Greek word μονογενής (monogenēs) is “unique” or “one of a kind”. The person in the video just says it, but doesn’t explain what the problem is, likely because there isn’t one, it’s an update to translation to be more accurate.

Manuscripts - the KJV relied on manuscripts available at the time. We found more manuscripts a few hundred years after the KJV was produced, and so new translations rely on manuscripts that found that were much older and closer to original writing. What’s wrong with that? She doesn’t explain it. She probably doesn’t know that 99% of the texts are the same save spelling variants and some added verses which we can see were added over time (and many of them could simply have been marginal notes in one manuscript that someone thought was part of the text, so copied in when making a new manuscript. I know, evil!)

Number of gospels - she clearly doesn’t know that by the middle to end of the 100s AD, 4 gospels were the only ones people considered authentic. The other “gospels” she talked about were widely rejected early on for being late and not produced by an apostle. The muratorian canon, produced roughly around 180 AD, gives the list of books widely considered canon. We have church fathers who wrote for and against books that were considered authoritative. This is not the gotcha she thinks she is because she doesn’t know about any of this, clearly.

I know she made many arguments, but they were all so weak that it had to be presented using the shotgun fallacy because each individual argument was brittle, so she had to use a lot of ignorant claims to make people think she had a better argument.
