One of the key foundation books of the English Reformation, The Obedience of a Christian Man (1528) makes a radical challenge to the established order of the all-powerful Church of its time. Himself a priest, Tyndale boldly claims that there is just one social structure created by God to which all must be obedient, without the intervention of the rule of the Pope. He argues that Christians cannot be saved simply by performing ceremonies or by hearing the Scriptures in Latin, which most could not understand, and that all should have access to the Bible in their own language — an idea that was then both bold and dangerous. Powerful in thought and theological learning, this is a landmark in religious and political thinking.
