Magnifica Humanitas §75

⁷⁵ The Church’s social teaching emphasizes that solidarity is both a principle and a virtue. As a principle, it expresses the objective order of relationships among individuals, groups and peoples, pointing to an awareness of interdependence whereby the good of each person depends on the good of others. As a virtue, it requires a “firm and persevering determination” to strive for the common good, with particular attention to those most in need. Pope Francis noted that solidarity is “a way of making history” that creates communities and not just masses of individuals. For this reason, it requires a modest and shared way of life, the ability to forego immediate benefits in order to create opportunities for others in the future, and a willingness to challenge habits and privileges — including those related to digital consumption and the use of technology — when they prevent others from living with dignity.
