“You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot. You are the light of the world. A town built on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.”
- Matthew 5:13-16
Social Justice "concerns the social, political, and economic aspects and, above all, the structural dimension of problems and their respective solutions" (Compendium of the Social Doctrine of the Church, no. 201). We step with this foot when we work to address the root causes of problems facing our communities by advocating for just public policies and helping to change the social structures that contribute to suffering and injustice at home and around the world.
Charitable Works are our "response to immediate needs and specific situations: feeding the hungry, clothing the naked, caring for and healing the sick, visiting those in prison, etc." (Deus Caritas Est, no. 31). We step with the Charitable Works foot when we work to aid or assist others both locally and globally to meet their immediate, short-term needs. Examples include engaging in direct service or providing food, clothing, shelter, or monetary assistance to help those in need.
