It began in 1951 as an outgrowth of the charitable works of Luis Ruiz Suarez SJ, and his Casa Ricci Social Services.

[1] The efforts of the Casa Ricci division remained focused on work among lepers and then AIDS victims throughout China, while Caritas Macau began increasing programs in Macau, founding Family Casework & Assistance Service, Our Lady of Mt.

Services to diverse groups continued: the homeless, ex-prisoners, youth, the elderly, and kindergarten and nursery schools.

In 2005 Caritas opened a performing arts program for young people, Teatro Clementina Leitão Ho Brito, to enhance their spiritual and cultural values.

In 2007 the care home Rising Sun Areia Preta was opened for people with physical disabilities.

In 2009 the large Centro de Santa Margarida was opened in the village of Cheok Ka, Taipa, to consolidate other services and assist in training rehabilitation caregivers.
