***The problem of literacy was faced by all sides, as was the challenge of making copies prior to the printing press.
Had the response to Wycliffe been to distribute scripture in an approved English translation to the congregations and people, then I would concede your point. However, the response was to try to stop any unauthorized translation, and then either not make an authorized one, or not distribute it, thus preventing common men from reading scripture - if they could read, or knew someone who did.***
All 1 or 2 percent? Each church had Scripture, labouriously copied out by hand at that point. But again, I must come back to the idea that England was a minor backwater, much like, oh, say Bhutan or Togo today.
Now, with the luxury of eagle eyed hindsight, would I have handled it differently? Sure.
***FWIW - for Germany, I suspect the problem was the type of German, and Luther succeeded because he went for the vernacular instead of the higher German languages.***
Luther’s Bible went hand in hand with the Reformation, which owes its success to the German princes, out for secular power. Their success spilled out into neighbouring countries and north to Scandinavia.
Secular power and material gain through wholesale theft.
