Chicago, IL (Aug. 28, 2020) – Rev. William J. Costello, retired priest of the Archdiocese of Chicago and former associate pastor of St. Eugene Parish in Chicago passed away Sunday, Aug. 23. He was 82.

Costello was born on Feb. 10, 1938 in Chicago. He attended St. Gabriel Catholic School in Chicago, Quigley Preparatory Seminary in Chicago and the University of St. Mary of the Lake/Mundelein Seminary in Mundelein, Ill.

He was ordained to the priesthood on April 30, 1964, by Albert Cardinal Meyer, and celebrated his first solemn Mass on May 3 of the same year at St. Gabriel Parish in Chicago.

He last served at St. Eugene Parish before retiring in 2008.

“Fr. Bill loved being a priest,” said Rev. John Ryan, pastor emeritus at St. Dismas Parish and a classmate of Costello. “He certainly loved the people at the parishes he served. He was a true servant of the Lord, very faithful to his duties and totally dedicated to his parishes.”
