At first the Corneloups lived with Ms Briguglio and her family in a unit she owned, before they moved together to a rental property.
While they were living there, Ms Briguglio sold her unit and from the profit she made gave $47,000 to Mr Corneloup.
She said it was at a time that she was being threatened with time at Unity House.
"I was desperate to be repentant and I thought how can I prove it? Because they can't look into my heart," she said.
"How can I do something outwardly to show that I'm repentant and I was thinking maybe if I give him a chunk of money and show that I'm not attached to it, perhaps he might believe me."
Sam Corneloup said he repeatedly refused the money at first, but eventually accepted it, although he put the figure between $35,000 and $40,000.
"In the end, of course, if someone wants to desperately give you $40,000, or $35,000 or something and especially when they've done a lot of things to ruin your life in a sense and you know stop all business activities because ..." he said
Sam Corneloup said he spent much of the money paying off church debt, but later understood the money should have gone to Ms Briguglio daughters, so he paid $35,000 to Ms Alinejad.
While Ms Briguglio and Ms Alinejad were sharing a house with Sam Corneloup and his family, Ms Alinejad drew up a "headship" contract that stated Ms Alinejad must submit to Sam Corneloup as the male head of the household.
It was signed by Ms Alinejad, Sam Corneloup and Ms Briguglio.
"[The contract was] not to say that women cannot work, cannot leave the home," Sam Corneloup said.
"It's more an issue of there has to be a leader in a household and the Bible places that leadership firmly upon the male, not upon the women, ever."
Daughters have been 'manipulated and controlled'
Ms Briguglio said she has lost all contact with her daughter because of Sam Corneloup.
"Unfortunately I haven't been able to communicate with Alecia because Sam told her that if I saw her face to face that I would manipulate her," she said.
Ms Briguglio said she had a close relationship with her two daughters before joining Street Church, but by the time she left Sam Corneloup's home, she felt she could not confide in them, even when she finally decided to break away and leave the house.
"I couldn't tell her. I couldn't tell her that I was going to run away because she wouldn't come with me and then she would have told him and then he would have stopped me from leaving," she said.
"And I just drove to a friend's house, not knowing if she was going to be home and I thought I don't care if I have to sleep in my car, I'm not going back. It's a cult."
Ms Briguglio's other daughter Aysan is married to Sam Corneloup's best friend Jesse Chetcuti, and they have a 18-month-old son.
Since leaving she has had little contact with any of her family members, and believed that was because they were 'being manipulated and controlled'.
"I found out my mobile number's been blocked from their mobiles so ... text messages I've sent, they've not received. My emails are blocked. I'm not allowed to speak to them," she said.
However Ms Alinejad said Ms Briguglio's lack of contact with the family was her own decision.
"I love her so much but I have to tell you like it's very frustrating when someone is dishonest about the way they treated you and when they won't let you live your life," she said.
"I just want to do my PhD. I just want to do my work. I don't want to get emails at my Flinders address, I don't want to be getting letters, I don't want to be getting phone calls from her and her church group, apparently church group.
"I don't want any of that. I just want to live my life and be free."
Different views on issues see Street Church brothers spilt
Sam Corneloup and his wife Debbie are considering going one step further by adopting Ms Alinejad.
"Nina - who's my biological mother, who's raised me from birth as best she could - is not my mother. She's not maternal," Ms Alinejad said.
Sam Corneloup said he and his wife might decide to adopt Ms Alinejad but it was "not really what we're after".
"What we're really after is just basically living at peace in a family and just being loving towards each other," he said.
But 7:30 South Australia understands the issue of adoption, along with some of the disciplinary methods Sam Corneloup was using in his household, has created a split between Sam and his brother Caleb.
Caleb Corneloup declined to be interviewed by 7:30 South Australia, but provided the following statement.
"We defend Samuel's position regarding the money from Nina, however we do reject any adoption of Alecia and state that it is unbiblical, unorthodox and not recognised under Australia law," the statement said.
"Because Sam ... and Alecia have left the church we are no longer in a position to correct him."
'This is turning into a cult'
Mr Egel said he was shocked to hear Mr Corneloup was considering adopting Ms Alinejad.
"When I heard about this new level that they'd gone to about adopting 24-year-olds and adopting adults I thought no, this is turning into a cult," he said.
However Mr Corneloup denied that allegation, saying he was a Christian man who was just trying to help others.
"A cult is someone who literally just uses people, they live in a mansion on some island somewhere, taking everybody's money," he said.
"A cult is not someone who rents a place, drives a Camry and is just trying to help people and all of his money since he became a Christian has been given to people for his, for the past 10 years."
Within an hour of 7:30 South Australia contacting Sam Corneloup about this story, a call was made to Ms Briguglio's workplace alleging she had abused her children.
The person identified himself as a psychologist called Tim Gracie, but there is no registered psychologist by that name in South Australia.
Mr Corneloup and Ms Alinejad denied the call was made as a result of 7:30 South Australia's enquires.
