In 1957, she was called to participate in a mercy mission with three other sisters in the Philippines to work with the Columban community there. While living in Tubod, on the island of Mindanao, they planned to build an elementary school and began ministries in education, health care and social work.

After returning to the United States, Sister Mary Christina became principal of St. Martin School in Buffalo. She served at Madonna High School in Niagara Falls and Mount Mercy Academy in Buffalo, serving as both a faculty member and assistant principal at the latter.
