GOD preserved ALL the ancient Scriptural mss. HE wants us to have. The stories behind the preservations of Sinaiticus & Vaticanus clearly show God's hand in it.You only know what you have been indoctrinated into. You and I know it isn’t about the translation but what manu scripts the translation was translated from. You cannot prove anything but that you have been duped into accepting corrupt manu scripts. Ever wonder why the minority texts support Roman Catholic errors I don’t ?
And the KJV differs from its sources in more than one place. And far as we know, Beza's revision of the TR differs from its sources in at least one place.
You actually have no valid excuses for being KJVO except believing some material from some quack.
