Father Bajorek, who was born in Homewood, Ill., grew up in a suburb of Cleveland.
For three years while at St. Charles Borromeo Seminary, he spent his summers in Germany working at a brewery. In his other travels, he visited Ireland, Italy, and the Cabrini Mission in Swaziland.
He spent seven more summers at the University of San Francisco, where he earned a master's degree in applied spirituality, and then helped lead the program.
Father Bajorek was athletic and maintained a healthy diet, which made the cancer diagnosis all the more shocking to his friends and parishioners.
Though he was a collegial pastor, he was introverted and comfortable being quiet, Bialecki said.
"That's why he was a good marathon runner," she said. "He could live with the quiet for all those many miles."
He completed 19 marathons, including five in San Francisco and one in Boston.
Father Bajorek was ordained by Cardinal John Krol in 1980. He taught theology and coached athletics at St. James High School in Chester. He worked as parochial vicar at Holy Martyrs Parish in Oreland and Our Lady of Hope Parish in Philadelphia.
He was pastor at St. Carthage, Our Mother of Sorrows, and St. Ignatius of Loyola in Philadelphia before his appointment at St. John Chrysostom in 2003.
In addition to his mother, Father Bajorek is survived by a brother, Michael, and a sister, Patti Kettle.
