Medical Mission Sisters

[4][5] Dengel became convinced that only a group of Religious Sisters who had been professionally trained as physicians could reach the women in that region.

[12] Response was so strong to the song that other songs were written and a marathon eight-hour recording session with the original group of sisters was commissioned in Philadelphia in early 1966 that resulted in enough material to fill a number of albums, with the bulk being released on Joy is Like the Rain, I Know the Secret and Knock Knock.

Other tracks from those sessions appeared interspersed with newer recordings on subsequent albums featuring a rotating cast of singers.

[13] In 1965, at the request of the Roman Catholic Archdiocese of Addis Ababa in Ethiopia, Mother Anna made a visit to that nation to investigate the possibilities of starting a hospital for the people there.

[16] The Sisters serve through health care and education, wholeness and wellness programs, the development of women, work for justice, worship and spirituality, and music and song.
