Elizabeth Rose Struhs died in January 2022 at her family's home west of Brisbane after her parents and brother joined other members of "the Saints" religious group to hold a vigil and pray around her.
The child's health deteriorated during the six days without her prescribed insulin for type-1 diabetes and she died lying on a mattress in the living room.
Elizabeth's father, Jason Richard Struhs, 53, mother Kerrie Elizabeth Struhs, 49, and brother Zachary Alan Struhs, 22, were among the 14 church group members being sentenced for manslaughter in Brisbane Supreme Court on Wednesday, along with Saints leader Brendan Stevens.
Justice Martin Burns said each of the church members encouraged Jason Struhs to stop his daughter's insulin, leading to their responsibility in her death.
"You encouraged Jason Struhs, not just to have faith, you encouraged him to have your faith," he told the court on Wednesday.
"The end goal was just as clearly intended by you all for Jason Struhs to cease administering insulin to Elizabeth."
Justice Burns said Elizabeth suffered greatly in the lead-up to her death, and her parents and the religious members were blinded by their faith.
"I am left with no other conclusion that you allowed your faith to blind you to the real plight Elizabeth, suffered a slow and painful death and you are all in one way or another, responsible," Justice Burns said.
He slammed the group for taking the "life of a vibrant, happy child who should have gone on to enjoy a full life".
The Saints members were found guilty of manslaughter on January 31 after claiming at a nine-week, judge-only 2024 trial they were acting on their religious beliefs that included rejecting modern medicine as "witchcraft".
Members told police they welcomed Elizabeth's death as it was a chance for God to resurrect her and show divine power to non-believers.
Trial witnesses described the Saints as a "cult", accusing them of brainwashing Jason Struhs and others.
Jason Struhs signed a diabetes management plan for his daughter after his wife was jailed in July 2021 for failing to provide Elizabeth with the necessities of life.
After his wife returned on December 16, 2021, he stopped giving Elizabeth her rapid-acting insulin on New Year's Day.
When that made the Saints "happy", he ceased her remaining slow-release doses.
Six days later the Saints found Elizabeth unresponsive.
She died and when police responded to her father's triple zero call made about 36 hours later, the Saints members were present singing religious songs.
Jason Struhs and Stevens had been on trial for murder by reckless indifference to life with the rest facing manslaughter charges.
Every defendant represented themselves at trial, refusing to enter pleas.
Therese Maria Stevens, 37, Sebastian James Stevens, 24, Loretta Mary Stevens, 67, Camellia Claire Stevens, 29, Andrea Louise Stevens, 35, Alexander Francis Stevens, 26, Acacia Naree Stevens, 32, Samantha Emily Schoenfisch, 26, Lachlan Stuart Schoenfisch, 34, and Keita Courtney Martin, 24 are the other members being sentenced.
