Don't know about any tweaking. Up until then the only bible was in latin and only allowed to be read by the priests. King James 'Authorised' it ie allowed it to be printed and available for the common people to read. You can't really tweak the text, original greek and Hebrew manuscripts still have to be translated by scholars and that translation has stood the test of time.But KIng James tweaked it to suite his needs, did he not?
I have been meaning to try and get versions of the original 70 odd gospels - I've always been intereted in how different they are from Matthew, Mark, Luke and John. And just these 4 have been written for different converts, you'll have to correct me if I'm wrong but Matthew was written for Jewish converts, hence cites a lot of old scriptures from Jewish prophecy and text.
There is one other point that always gets me about 'organised religion'. We have a god of peace and love, but most of the hymns are about christain soldiers, kings of this and that, fighting the good fight, and war - call me strange but it doesn't add up :^O
In Christianity and fights or battles are of the spiritual sense. Fighting the good fight. No killers in NI for example, on any side can be classed as Christian. God is a god of Love and peace. Its us that divide ourselves and cause all the violence and sectarianism.
