The Rev. Vincent J. Assing, S.S.J., who served St. Pius V Church at Schroeder Street and Edmondson Avenue on four different occasions, died Sunday after an apparent heart attack at St. Joseph Manor.

Father Assing, 89, had lived at the manor, the retirement home of the Society of St. Joseph at 911 W. Lake Ave., for 20 years.

A Mass of Christian burial for Father Assing was being offered today at St. Joseph Manor.

At his retirement in 1972, he had been chaplain since 1961 of St. Frances Academy of the Oblate Sisters of Providence on East Chase Street.

He was stationed at St. Pius V in 1932 and 1933, from 1935 to 1937, again from 1945 to 1951 and finally from 1954 to 1961.

He was a native of New York City and the son of a policeman. He was ordained in 1932.

He is survived by several cousins.
