Supporters of Pope Leo XIV gathered Saturday, not in a cathedral or a church, but a baseball stadium the pope once frequented years as Robert Francis Prevost.

CHICAGO (RNS) — At Rate Field, the home of the Chicago White Sox, some 30,000 celebrated a native son, Pope Leo XIV, Saturday afternoon (June 14) at a Mass organized by the Archdiocese of Chicago. Leo appeared via video from Rome, in a prerecorded message encouraging young people to engage in the community of the church.

At an event celebrating the city's native son, Cardinal Blase Cupich spoke on immigration and the undocumented in his "Sermon on the Mound."
