Kathryn Wickey Orso, 57. who had been a teacher, consultant and speaker in religious education in this area, died of cancer Tuesday at her home in Towson, Md.

She was the wife of the Rev. Dr. Paul M. Orso, president on the Maryland Synod of the Lutheran Church of America.

They had lived in Bethesda from 1953 to 1968 while he served as executive director of the Lutheran Inner Mission Society of Washington and then of Lutheran Social Services of Greater Washington.

Dr. Orso, who held a dual doctorate in education from Wesley Theological Seminary and American University, earned those degrees after serving from 1956 to 1966 as director of Christian education at St. Luke's Lutheran Church in Silver Spring.

She became a consultant in religious education and an instructor in Parent Effectiveness Training. After leaving this area, she was associated with the Baltimore city schools.

Dr. Orso was born in Fargo, N.D., and came to Washington as a child. She graduated from Wittenburg University in Springfield, Ohio, in 1942.

She wrote numerous articles for the Lutheran Church Women of the Lutheran Church in America and two books, "It's Great to Pray" and "Parenthood: A Commitment in Faith."

She was a member of the American Association for the Gifted, the Association of Professors and Researchers in Religious Education, the Council for Exceptional Children, the Religious Education Association in America and the League of Women Voters.

In addition to her husband, she is survived by a son, Donald P., of Arnold, Md.; a daughter, Carolyn O. Bertelsmeyer, of St. Louis, Mo.; her mother, Ethel Wickey, of Bethesda; three sisters, Phyllis Waltmeyer, of Pottstown, Pa., Vivian Otto, of Washington, and Charlotte Diehl, of Pittsburgh, and four grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to a memorial fund for religious education in her name at the Maryland Synod in Baltimore.
