John Wycliffe translated the Bible to English a century and a half before Luther and Tyndale ... against the wishes of the RCC. It was banned and almost all copies destroyed. Control-freaks in the RCC didn’t want the average Joe Christian to know how far the RCC had deviated from Scripture.
Of course it was banned.
Why shouldn’t an unauthorized translation be a guy with an axe to grind?
You ignored the multitude of approved translations that were in the local vernacular. You also ignore that the homily was in the vernacular, and that the priest would have spoken both Latin and the local language.
Your claim is old and easily debunked. Check the link I posted earlier.
