According to the Caritas concept, the parishes were supposed to organise social and charitable activities at a local level, with varying degrees of success and effectiveness.

Special Caritas Sundays, featuring illustrated presentations and other activities, were organised to raise awareness among parishioners.

Internal crises emerged, leading to the resignation of Director Giuseppe Crivelli and prompting a revision of the statutes in 1950.

[3] A significant relief operation took place between 1968 and 1970 for victims of the Biafran War in Nigeria, bringing in more than 11 million CHF in donations.

This surpassed the association's existing infrastructure capabilities and triggered a period of growth, followed by another internal crisis, which culminated in 1971 with the resignation of Director Peter Kuhn (1935–1995).

The regional Caritas organisations support people affected by poverty in Switzerland and contribute therewith to social integration.
