LOL, that is completely false. Perhaps you should read other (non-biased) scholars and sources and you will clearly see there is no concrete agreement on who wrote the bible as a whole tome.
Well, I can certainly see how you would come to that conclusion brother, but as for me, and as I have stated herein before, my personal relationship with Jesus is my own. I have proof internal to myself, and I feel no need to attempt to prove it to others because if held to those standards, then they would not be considered as proof, but only opinion.
But to answer your question straightforwardly, I feel some of the scripture is indeed doctored in the new versions/translations. In fact, this is a PROVEN fact that they have been changed by multiple sources over multiple dates. As an example, the concept of a fire and brimstone type hell was NEVER in the original Hebrew...therefore, all subsequent translations that ADDED this concocted type of hell are strictly erroneous as they contradict what the ORIGINAL Hebrew stated. So, are THOSE additions God inspired, or made man? Clearly they are man-made if the translations do not match the original source text. So, we must use our best, personal judgement on what is real deal God inspired original scripture and what might be fabricated by man.
So, in my personal opinion, as Christians we have to "personally" decide what constitutes proof...to us...in order to base our personal conclusion about God. My salvation is not dependent on what others think, it is only dependent on what God thinks. However, just because I cannot prove my conclusions to others through experimentation and repeatability as what the scientific method requires, it doesn't mean I am forced to forgo my personal conclusions. That's the beauty of faith, and God's personal connection to our personal situations.
