Confutatio Augustana
The Confutatio Augustana was the Roman Catholic refutation (confutatio) of the Augsburg Confession, often referred to in the theological literature as simply the Confutatio. On 25 June 1530 the Protestant Imperial States of the realm met at the Diet of Augsburg, and presented Charles V with the Augsburg Confession, largely the work of Philip Melanchthon setting out the doctrines and practices of the church in the Protestant principalities.
