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. The spelling of this title is now commonly modernized 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.
