Willliam Tyndale (1494-1536) translated the Bible into English. That may not seem very earth-shattering - until you consider the times he lived in. To possess the scriptures in English was to invite the death sentence, unless you had a licensed copy (presumably the only people who were allowed licences were clergymen!).
I owe a debt of gratitude to William Tyndale. Without him (and therefore his Bible), the ancestors of mine who were searching for spiritual truth would have been lost. We see Bibles on shelves and in hotel rooms and don't give them another thought. My own quest for spiritual truth would have been made much more difficult.
Thank you, William Tyndale.
