Hence they were resolutely opposed to any idea of reform; for to begin making changes in the Church's system would be a tacit admission that Luther had some show of reason on his side.
An attempt in 1543 to approach Luther only increased the Reformer's hostility and rendered Schwenkfeld's situation still more precarious.
He wrote many similar works, among which is a Vindication of Luther against his recent English Assailants (1854).
Luther and his followers regarded vestments as among the adiaphora, and in the Churches which afterwards came to be known as "Lutheran" many of the traditional vestments were retained.
In the following year he went to Germany to be present as papal nuncio at the coronation of Charles V., and was also present at the diet of Worms, where he headed the opposition to Luther, advocating the most extreme measures to repress the doctrines of the reformer.
