John Keating was born in Chicago, Illinois, to Robert and Gertrude Keating.

While in Rome, he was ordained to the priesthood by Bishop Martin John O'Connor on December 20, 1958.
Following his return to Chicago, Keating served as a curate at Our Lady of Mount Carmel Church until 1960, when Cardinal Albert Gregory Meyer sent him back to Rome to study canon law. He later earned a doctorate in canon law from the Gregorian University in 1963.
