In the Catholic Church, a dogma is a definitive article of faith (de fide) that has been solemnly promulgated by the college of bishops at an ecumenical council or by the pope when speaking in a statement ex cathedra, in which the magisterium of the Church presents a particular doctrine as necessary for the belief of all Catholic faithful. For example, Christian dogma states that the resurrection of Jesus Christ is the basic truth from which salvation and life is derived for Christians. Dogmas regulate the language, how the truth of the resurrection is to be believed and communicated. One dogma is only a small part of the Christian faith, from which it derives its meaning. 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.
Dogma can also pertain to the collective body of the Church's dogmatic teachings and doctrine. The faithful are required to accept with the divine and Catholic faith everything the Church presents either as solemn decision or as general teaching. Yet not all teachings are dogma. The faithful are only required to accept those teachings as dogma if the Church clearly and specifically identifies them as infallible dogmas. Not all theological truths have been promulgated as dogmas. A tenet of the faith is that the Bible contains many sacred truths, which the faithful recognize and agree with, but which the Church has not defined as dogma. Most Church teachings are not dogma. Cardinal Avery Dulles pointed out that in the 800 pages of the Second Vatican Council documents, there is not one new statement for which infallibility is claimed.
