John Gilbert Blacktop, 81, from Morecambe in Lancashire, went on the run for nine days as he was sentenced in his absence at Bradford Crown Court last month.
Blacktop was found guilty of 33 counts of indecent assault, one count of rape and one count of attempted rape spanning between 1974 and 1977. The girls were aged between five and 14.
Some of his abuse occured at Christ Church Wyresdale Road in Lancaster, where he was choirmaster and organist.
Andy Woodmass, of Operation Fervent, said: "John Blacktop is a predatory sex offender who preyed on young girls to satisfy his own depraved sexual desires.
"I would like to give special mention to the victims who had the strength to come forward and report what had happened to them.
"Lancashire Constabulary remains committed to investigating allegations of this nature, no matter how historic, and no matter what the role, position and status of the alleged offender."
