Sister Rita Callanan, 80, told Fox News that she hopes the pontiff will look into her case and discuss with the Signatory, the Vatican's equivalent of the U.S. Supreme Court.

Callanan and another nun, Sister Catherine Rose Holzman, has been in and out of court against Perry since 2015 to fight against her purchase of the Convent of the Sisters of the Immaculate Heart of Mary in Los Feliz. Holzman, however, died last March, but Callanan vowed to continue their cause.

"They'll have to kill me first if they want to keep me quiet," the nun said, She also revealed that she has written Pope Francis a letter detailing their plight.

Callanan and her fellow nuns lived in the Los Feliz convent for 40 years until the Archdiocese of Los Angeles, after an agreement with the nuns, moved the occupants to retirement homes as the property was too big to maintain. Callanan, however, alleged that Archbishop José Horacio Gómez sold the property to Perry for $14.5 million without their approval. The nuns had a separate deal with restaurateur Dana Hollister to purchase the property for less than the price Perry offered.

Hollister was in the middle of renovating the convent when the archdiocese intervened. Perry also talked to the nuns about her purchase in 2014, but they could not agree on any terms. This prompted the archdiocese and Perry to file the lawsuit against Hollister and the nuns the following year.

"We do not agree with [Perry's] lifestyle that has strayed far from any faith," Callanan said to explain why they opposed Perry's offer. "At the end of our lives, we find ourselves fighting for justice and for what is right," she added.

In 2016, the courts decided that Perry is actually the new rightful owner of the Los Feliz property. Los Angeles County Superior Court Judge Stephanie Bowick ruled that the nuns' deal with Hollister was not legal and asked the restaurateur to pay the archdiocese $15 million.

Callanan claimed that the jury did not hear their side; hence she's planning the next steps with her attorney. The sister also told The Daily Beast that Gómez made a promise to take care of the nuns in their twilight years, but she recently learned that the archdiocese has not paid her health insurance hence it was canceled.
