Andrew,
Okay, we differ as to the first part of my statement, but what about the second:
Are you aware of the differences between the translations? Or more accurately, the Greek texts underlying them? Either the last twelve verses of Mark (16:9-20) are authentic, or they are not. Either 1 Timothy 3:16 reads "God was manifest in the flesh," or not, as per the modern versions (save those based on the Traditional Text). One version is superior (that is, correct) over the other. Are you aware of the issues and the arguments?
Ivan is right when he says there are threads here devoted to these questions, and which cover them quite thoroughly.
Is it solely Dr. White's testimony on which you are basing your certitude?
Steve
