Tyndale wanted anyone, rich or poor and especially the poor man, to have access to the unmediated word of God. Since Wyclif in the 14th century, the Lollards had been walking the country preaching the Gospel at great personal risk, but the English Bible they used was firstly manuscript (and very expensive) and secondly little more than a transliteration into poor English from the Latin (Vulgate) Bible. The 1408 Constitutions of Oxford made it effectively a capital offence to translate the Scriptures into English, and thus Tyndale had to effect his translation and its printing in hiding on the Continent.
At this time the English language was undergoing the "great vowel shift", effectively becoming intelligible to us. But the literate classes considered it a crude language, incapable of higher thought, which needed Latin, or some such proper language for expression. There was no literature in the new modern language. Then Tyndale's inflammatory text appeared, and spread like wildfire underground.
Tyndale was an exceptionally able scholar, fluent in all the European languages, and Greek too. He could even hear the Aramaic under the Greek text of Matthew. And we hear his translation today as beautiful English: this is because it is the underlying text of the New Testament of the King James bible of 1611. But at the time he was using the structure of the speech of the ordinary man, and turning this speech to unprecedented use. He claimed that the English of the ordinary man was very well matched to the ordinary Greek used by the New Testament writers, and his English is of the utmost clarity and immediacy. We still use it today! When we say things are "for the best" we are using Tyndale's text of Romans chapter 8 verse 28, one of very many places where King James does not improve Tyndale.
Thus, Tyndale's New Testament of 1526 is the first modern English book. And it has had enormous influence directly on us, since it has moulded the language, and moulded our thought with it right up to very modern times. When we hear and respond to the "Nine Lessons and Carols" from Kings College Cambridge, we are responding to Tyndale's text. And without Tyndale there would have been no Shakespeare! This is an important book!
The facsimile is an absolute delight. It is beautifully laid out and printed. The medium is certainly not the message, pace Marshall McLuhan, but it makes the book compelling to read. The popularity of this inflammatory text must have been boosted by the sheer pleasure of looking at the physical pages. This is a world changing book presented in a form of the very highest quality.
