Ben-Canaan was sentenced in the Christchurch District Court today.
Judge Raoul Neave says he has caused long-standing psychological damage to his victims.
He pleaded guilty to eight charges part-way through a jury trial at the Greymouth District Court last September.
A former Gloriavale member who was sexually abused in the Christian community when she was 13 years old told her abuser in court on Wednesday that he stole her childhood and her innocence.
The survivor broke down in tears in court reading her victim impact statement.
She says during the period she was abused she felt like she was living in a never-ending nightmare.
