Khabouris Manuscript

[judge]

One thing I've noticed about a lot of Peshitta primacists is that they claim that they claim that the Khabouris Codex is the oldest manuscript of the New Testament...this manuscript was carbon dated back to the 12th century.

I've not seen anyone claim this. The discussions I've seen here have been that there was an idea that it (or possibly another peshitta mss) may have been around the time of the oldest complete Greek NT mss, but that it probably was in fact much later.
