like reading the King James Version of the Bible, I just don't understand the language
I understand the KJV perfectly. It's nothing compared to Chaucer.
For some reason, I never had trouble understanding the KJV. I liked other translations better, but I read KJV on my first half-dozen or so times through the New Testament and never had a problem with understanding things. Of course, that was years ago, and I haven't done any Bible reading in a long time.
