Counter Reformation
Also known as the Catholic Reformation, generally refers to a period of
Roman Catholic Church history in the 16th and 17th centuries. The
Counter Reformation consisted of two related movements: 1)
a defensive reaction against the Protestant
Reformation, and 2) Catholic reform.
The Roman Catholic Church called the Council
of Trent partly as a defense against Protestantism. It defined
Catholic doctrine on questions disputed by Protestant theologians.
