Cathedral Centennial Celebration

Bishop Peter Christensen invites you to the centennial celebration of the Cathedral of St. John the Evangelist—Idaho’s only Roman Catholic cathedral—which was dedicated in 1921!

Save the date! Join us for mass on Corpus Christi Sunday—10 AM on June 6th—followed by a Eucharistic procession through downtown Boise. Then, stay for the day on the Cathedral block for a street festival with live music, food trucks, vendors, and family activities. You can also take a tour and see our recently restored tabernacle. It will be a day of prayer, fellowship and fun to commemorate our historic cathedral.
