This commitment to human dignity and the common good in Catholic Social teaching translates into the call for solidarity. Solidarity can be understood as a virtue, that is an habitual disposition, to stand with and for those who are marginalized and disadvantaged by systems and structures that we have put into place to facilitate our social interactions. Pope Francis put it this way in his Apostolic Exhortation 'On the Joy of the Gospel'—Evangellii Gaudium: Solidarity is a spontaneous reaction by those who recognize that the social function of property and the universal destination of goods are realities which come before private property. The private ownership of goods is justified by the need to protect and increase them, so that they can better serve the common good; for this reason, solidarity must be lived as the decision to restore to the poor what belongs to them. These convictions and habits of solidarity, when they are put into practice, open the way to other structural transformations and make them possible. Changing structures without generating new convictions and attitudes will only ensure that those same structures will become, sooner or later, corrupt, oppressive and ineffectual.
