Dogma in the Catholic Church

A dogma of the Catholic Church is defined as "a truth revealed by God, which the magisterium of the Church declared as binding". The Catechism of the Catholic Church states: The Church's Magisterium asserts that it exercises the authority it holds from Christ to the fullest extent when it defines dogmas, that is, when it proposes, in a form obliging Catholics to an irrevocable adherence of faith, truths contained in divine Revelation or also when it proposes, in a definitive way, truths having a necessary connection with these.
