Served on Faculty of Quigley Seminary North and South

Chicago, IL  (February 22, 2011) Fr. Frank Patrick Cassidy, a priest of the Archdiocese of Chicago for 43 years and a former faculty member at both the north and south campuses of Quigley Preparatory Seminary, died Friday, February 18, at Resurrection Hospital in Chicago. He was 79 years old.

Fr. Cassidy was born and raised in Chicago Heights. He graduated from St. Agnes School there and from Quigley Seminary North and the University of Saint Mary of the Lake / Mundelein Seminary. He was ordained in 1957 by Cardinal Stritch. His brother, Fr. John Cassidy, now a retired priest of the Archdiocese, was ordained the following year.

For two years following his ordination, he was the associate pastor of St. Philip Neri Parish on Chicago’s south side. From 1959 to 1970, Fr. Cassidy served on the faculty at both campuses of Quigley Seminary; first at Quigley North from 1959-61, and then at Quigley South from 1961-70, where he was also the Prefect of Discipline. During this time, Fr. Cassidy served as associate pastor at St. Francis de Paula Parish (1959-65) and then at St. Maurice (1965-70). St. Francis de Paula Parish closed and St. Maurice was combined with two other parishes in 2008 to form the new Blessed Sacrament Parish.

Fr. Cassidy did post-graduate studies during summers at the University of Norte Dame, earning a masters degree in history. He also earned a masters degree from Loyola University and one in theological studies from Catholic Theological Union in Chicago.

Fr. George McKenna, a fellow faculty member at Quigley and golfing partner of Fr. Cassidy for 40 years, described him as an excellent golfer who was very kind and charitable both on and off the golf course. “I never heard an unkind word or criticism from him, Fr. McKenna said, “even though he beat me most of the time.” He added that in everything, whether sports or life, Fr. Cassidy put zest into it. “He was a humble priest,” said McKenna, “and he valued his priesthood like ‘the pearl of great price.’”

Between 1970 and 1980, Fr. Cassidy served as associate pastor at two Chicago parishes: St. Walter Parish on the southwest side from 1970-75 and St. Stanislaus Bishop and Martyr on the northwest side, from 1975-80. He served at Queen of Apostles Parish in the south suburbs from 1980-85, first as administrator and then as associate pastor.

For one year, 1985-86, he was the associate pastor of St. Damian in the southwest suburbs. In June of 1986, Fr. Cassidy was named associate pastor at St. Nicholas of Tolentine Parish and continued as a senior priest to serve the parish until 2009, when he moved to St. Daniel the Prophet Parish to live with his brother.

Visitation for Fr. Cassidy will take place from 4 to 9 p.m. at St. Daniel the Prophet Church, 6612 West 54th Street in Chicago. Francis Cardinal George, OMI, Archbishop of Chicago, will be the main celebrant at a funeral Mass for Fr. Cassidy at 10 a.m. on Thursday, February 24, at St. Daniel the Prophet. Fr. George McKenna, a retired priest and longtime friend of Fr. Cassidy, will deliver the homily.

Interment is at Holy Sepulchre Cemetery in Alsip. In addition to Fr. John Cassidy, another brother, James Cassidy, survives him.
