I have asked that questions on a number of threads a number of times. I have yet to receive a suitable response, because if a person is intellectually honest they realize that there is no response.
The only real response I have ever received was from one poster who opined that had he lived in medieval Europe, he would have made certain that his family owned one, even if they had to sacrifice. The reality is that the "average" person in medieval Europe lived in poverty and would not earn enough money in their lifetime to purchase a Bible. And aside from this, even if they could afford a Bible, it was not as if you could go down the street to the neighborhood bookstore and buy one, they were hand inscribed and it took years to produce a single volume. But even if a person had the money (and remember that in those days you couldn't just borrow the money) and the time to wait (which is a negligible proposition because the average adult who had amassed the money to purchase a Bible wouldn't still be alive by the time his order was complete -- if a king or nobleman put in an order, your's would get "bumped") the fact still remains that the person in question would probably be illiterate.
In short, to devise a plan of Salvation that is so unattainable would be totally inconsistent with God's Omnipotence and Love.
Not to mention the fact that the RCC went to great lengths to purge the world of Bibles outside its control. Going so far as to make it a crime to own one, even executing those caught with even portions of Scripture.
That's just it. That whole line a reasoning does not fit with an easy yoke and light burden.
