Catechism of the Catholic Church
88 The Church's Magisterium exercises the authority it holds from Christ to the fullest extent when it defines dogmas, that is, when it proposes truths contained in divine Revelation or also when it proposes, in a definitive way, truths having a necessary connection with these."
89 There is an organic connection between our spiritual life and the dogmas. Dogmas are lights along the path of faith; they illuminate it and make it secure. Conversely, if our life is upright, our intellect and heart will be open to welcome the light shed by the dogmas of faith. 50
90 The mutual connections between dogmas, and their coherence, can be found in the whole of the Revelation of the mystery of Christ. 51 "In Catholic doctrine there exists an order or hierarchy of truths, since they vary in their relation to the foundation of the Christian faith." 52
