Catholic Social Teaching

Developing our conscience through the lens of understanding human dignity, solidarity, and subsidiarity, Catholics around the world are called to incorporate and live out the moral social teachings of the Catholic Church (CST) to bring around a more just society by developing communities that advocate for all people throughout their life by recognizing the inherent dignity of all humans from conception through natural death, ensuring people have adequate spiritual, financial, emotional, and environmental means to care for themselves, limiting the destruction of our shared home, encouraging the family to live out their vocation in society through the raising and education of their children with the insurance of being financially able to do so, and reducing the negative effect of consumer culture on society. CST calls for everyone to understand that we are connected to one another, and our actions have profound effects on others, even if they are invisible to us.

 "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. 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. The mutual connections between dogmas, and their coherence, can be found in the whole of the Revelation of the mystery of Christ. 'In Catholic doctrine there exists an order or 'hierarchy' of truths, since they vary in their relation to the foundation of the Christian faith.'" - Catechism of the Catholic Church nos. 88-90
