William Tyndale's original works are all in some way directed against the established
church of his time. A number of works begin from translations of Martin Luther, with
expansion and addition from Tyndale's own pen. 
In general, Tyndale advocates a
Bible-centred approach to the Christian religion, dismissing the authority of priests and
popes as largely a conspiracy to enrich prelates at the expense of ordinary people. His
longest work, The Obedience of a Christian Man (1528), attempts to build a view of
political authority with biblical warrant. An Answer to Sir Thomas More's Dialogue
(1531) is the best brief account of his theological position.
Works:
The Introduction to the New Testament [Pathway into Holy Scripture] (1525)
The Parable of the Wicked Mammon (1528)
The Obedience of a Christian Man (1528)
The Practice of Prelates (1530)
An Answer to Sir Thomas More's Dialogue (1531)
