Mary Grace Cutrona, 57, a lector at The Church of the Little Flower in Bethesda and a member of the board of directors of the House of Ruth, which provides shelter for homeless women, died Friday at Walter Reed Army Medical Center. She had rheumatoid arthritis.

Mrs. Cutrona was born in Washington, graduated from McKinley Technical High School, Georgetown Visitation Junior College and Trinity College, where she earned a bachelor's degree in 1945. In the same year, she married Joseph F. H. Cutrona, then a captain in the Army and now a retired brigadier general.

Shortly after World War II, she accompanied her husband to Germany, where she worked on the European edition of The Stars and Stripes newspaper. She also accompanied her husband to various posts in the United States and to Alaska. The family always maintained a home in the Washington area and has lived in Bethesda since 1973.

Mrs. Cutrona became a lector at The Church of the Little Flower after graduating last year as a member of the first class of the Education for Pastoral Service for Women of the Archdiocese of Washington. She was also a teacher in the Confraternity foro Christian Doctrine at the church. She was a member of Community for His Kingdom Prayer Group.

In addition to her work with the House of Ruth, she was a volunteer for SOME (So Others Might Eat), an organization which provides meals for the needy.

Besides her husband of Bethesda, survivors include three daughters, Susan of Seattle, and Maria and Lisa, both of Bethesda; four sons, Joseph F. H. Jr. of Branford, Conn., Richard Ryan of Greesboro, N.C., Sada Sat Singh Khdsa of Inda, and Timothy of Bethesda; one brother, Michael William Ryan of Bowie; two sisters, Mrs. Hans Rogger of Los Angeles, and Mrs. Gordon Allen of Arlington, and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Trinity College Education for Pastoral Service, Washington, D. C., or to the Northwest Jesuit Mission.
