Amid security worries, millions of pilgrims are expected to descend on Rome for a Jubilee Year of major Catholic celebrations throughout 2025. Here are the highlights.

This significant event will be mirrored locally in Cincinnati, where Archbishop Dennis Schnurr is set to open the Jubilee Year.

According to the Vatican, the tradition began in 1300 when Pope Boniface VII announced the first Jubilee. Later, Jubilees came to be celebrated every 25 years.
