Within the vibrant life of the Catholic Church today, many currents of spirituality and specific projects can shed light on the encyclical’s themes and provide examples of what its principles might look like in practice. This note focuses on how Chiara Lubich’s spirituality of unity might offer a helpful way for people to understand how to live these principles in their everyday lives. It also discusses how the “Economy of Communion” and other concrete projects and practices of Focolare, the movement Lubich founded, foster economic justice and human development.
