We truthfully belong together in God. This is the spiritual basis of solidarity.
Here too we find the ground of all Christian action. As prayer leads us into the house of God and God’s people, so action leads us back into the world to work there for reconciliation, unity, and peace…. All Christian action – whether it is visiting the sick, feeding the hungry, clothing the naked, or working for a more just and peaceful society – is a manifestation of the human solidarity revealed to us in the house of God. It is not an anxious human effort to create a better world. It is a confident expression of the truth that in Christ, death, evil, and destruction have been overcome. It is not a fearful attempt to restore a broken order. It is a joyful assertion that in Christ all order has already been restored. It is not a nervous effort to bring divided people together, but a celebration of an already established unity. Thus action is not activism. An activist wants to heal, restore, redeem, and re-create, but those acting within the house of God point through their action to the healing, restoring, redeeming, and re-creating presence of God.
