The Rev. Bernard J. Nowicki and the Rev. Stanley M. Bilinski Jr. became bishops in front of an audience of several hundred parishioners and well-wishers at St. Stanislaus Cathedral in South Scranton.
Bishop Nowicki was also installed as ninth bishop of the Central Diocese, a role that includes being pastor of St. Stanislaus, the denomination's mother church.
Bishop Nowicki, a longtime pastor at a church in Bayonne, N.J., who was raised in a historically Polish neighborhood of Buffalo, N.Y., will move to Scranton at the end of October.
Bishop Bilinski will be bishop of the Chicago-based Western Diocese.
Both were elected to their new roles during a special synod in June.
The two men were consecrated by Prime Bishop Anthony Mikovsky and several fellow bishops, who blessed the priests, prayed over them and gave each a cross to wear, a ring, a staff, and a Book of Gospels.
"This is a joyful, wonderful occasion," Prime Bishop Mikovsky said during his homily.
He encouraged the faithful to work with the bishops and urged the bishops to cherish their promise to teach and lead.
"Let the faithful, let all of humanity, see God in you," he said.
The Scranton-based Polish National Catholic Church counts more than 25,000 members in the United States.
The Central Diocese, which includes churches in Pennsylvania, New Jersey, New York and several other states, is the denomination's largest.
