"The Obedience of a Christen man, and how Christen rulers ought to govern, wherein also (if thou mark diligently) thou shalt find eyes to perceive the crafty convience of all iugglers" is a 1528 book by the English Protestant author William Tyndale.
Its title is now commonly modernized in its spelling and abbreviated to "The Obedience of a Christian Man".
It was first published by Merten de Keyser in Antwerp, and is best known for advocating that the king of a country was the head of that country's church, rather than the pope, and to be the first instance, in the English language at any rate, of advocating the divine right of kings, a concept mistakenly attributed to the Catholic Church.
William Tyndale (1494 - 1536) was an English scholar who became a leading figure in the Protestant Reformation in the years leading up to his execution. He is well known for his translation of the Bible into English.
