The overwhelming majority of Bible manuscripts existent throughout history have been the text found in Antioch. They have always been available in some form, either in copies of the original Greek, or the old Latin of 150 AD, (NOT to be confused with Jerome's corrupt "Vulgate") or the Syrian Peshetto of 157 AD.
That it would be difficult indeed to gather all of these sources together and place them in the hands of the common man gives credence to God's reasoning for the collation and translation of the King James Bible.
