Caritas Southwark (CS) is the social action agency of the archdiocese. Our function is to build charitable networks of organised social action with parishes' schools and other organisations across South London and Kent.

"It is easy to delegate charity to others, yet the calling of every Christian is to become personally involved." The pope thanked God for the men and women "of every age and social status" who devote themselves to caring for the poor and excluded, the "ordinary people who quietly make themselves poor among the poor.“

-Pope Francis World Day of the Poor 2023
