“We mourn the loss of a dedicated shepherd. For sixty years, Cardinal Szoka gave himself totally to his priestly service of Christ and his Church.”

“He has gone home to the Heavenly Father with our prayers. May the Lord give him the reward of his labors,” said Archbishop Allen H. Vigneron, current archbishop of Detroit.

Born on Sept.14, 1927, Edmund Casimir Szoka grew up in Grand Rapids as the child of Polish immigrants. He attended St. Joseph Seminary and was ordained a priest on June 5, 1954 in Marquette. He served his first years as an assistant priest at St. Francis in Manistique, Michigan.

He was also appointed President of the Governatorate of Vatican City State and of the Pontifical Commission for Vatican City State by Pope John Paul II, where he served until 2006.

Just after he turned seventy-nine, Cardinal Szoka resigned and officially retired from active ministry on Sept.15, 2006 with Pope Benedict XVI’s approval. Following his retirement, he lived in Northville, Michigan until his death o n Aug. 20, 2014.
