Massaro, Section 5 and 6

The teaching of Catholic social has aimed to apply their principles to new situations in the modern world. It also had to acclimate its teaching and message to new circumstances and has limits on property holding that people can not gain interest on housing. It teaches you that  God intends the Earth for all his children and that everyone should deserve the right to use it for nourishment. Catholic social teaching also contends that a world without labor unions would be  much less  approving towards environment for achieving justice and fair sharing of earth's resources.  Human labor also contains the human response to God, who invites all people to become cocreators of the material world.
