A massive chorus of devotees of all ages will take to the streets Sunday, clad in white garb, bright red sashes and carrying bouquets of flowers, barefoot or in socks, shouting “Primo Deo San Sebastiano!” as they run into their church, then parade around the block hoisting a heavy likeness of their patron saint.

“First God and then St. Sebastian!” is the well-known cry during the culmination of 98th annual St. Sebastian feast, the final element of the three-day festival of Catholic faith at St. Sebastian Church, 155 Washington St./Route 66, which follows the 11 a.m. Mass.
