The Missionaries of Charity (Latin: Congregatio Missionariarum a Caritate) is a Catholic (Latin Church) religious congregation established in 1950 by Mother Teresa, now known in the Catholic Church as Saint Teresa of Calcutta. In 2020, it consisted of 5,167 religious sisters. Members of the order designate their affiliation using the order's initials, "M.C.". A member of the congregation must adhere to the vows of chastity, poverty, obedience, and the fourth vow, to give "wholehearted free service to the poorest of the poor." Today, the order consists of both contemplative and active branches in several countries.
Missionaries care for those who include refugees, former prostitutes, the mentally ill, sick children, abandoned children, lepers, people with AIDS, the aged, and convalescent. They have schools that are run by volunteers to teach abandoned street children and run soup kitchens as well as other services according to the community needs. These services are provided, without charge, to people regardless of their religion or social status.
