Mercedes de Jesús Molina
Mercedes de Jesús Molina was born on 24 September 1828 in Baba, Los Ríos Province, Ecuador. She was the daughter of Miguel Molina y Arbeláez and Rosa Ayala y Aguilar. After the death of her father, two years later, Mercedes and her mother moved to Guayaquil. Then at the age of fifteen Mercedes suffered the death of her mother. A bad fall from a horse brought about her conversion to absolute piety and strict penance. From then on she devoted her life to care of abandoned children. She did this first as mother and teacher to orphans in Guayaquil then in Cuenca, where she shared a home with Saint Narcisa de Jesús. Mercedes later volunteered her services to the Jesuits to assist in the conversion of the Jivaroan peoples. After the missionaries had to give up their mission territory, Mercedes settled in Riobamba. There she took vows of poverty, chasity and obedience and founded the Sisters of Mariana de Jesús, named after Saint Mariana de Jesús, on 14 April 1873. This institute provided care orphans, converts, and women who had been released from prison. She died ten years later in Riobamba on 12 June 1883. Mercedes was beautified on 1 February 1985 by Pope John Paul II in Guayaquil.
