CCC 1942 The virtue of solidarity goes beyond material goods. In spreading the spiritual goods of the faith, the Church has promoted, and often opened new paths for, the development of temporal goods as well. And so throughout the centuries has the Lord’s saying been verified: “Seek first his kingdom and his righteousness, and all these things shall be yours as well”:1
For two thousand years this sentiment has lived and endured in the soul of the Church, impelling souls then and now to the heroic charity of monastic farmers, liberators of slaves, healers of the sick, and messengers of faith, civilization, and science to all generations and all peoples for the sake of creating the social conditions capable of offering to everyone possible a life worthy of man and of a Christian.2
