The Sister of Perpetual Indulgence (SPI) is a far-left LGBT advocacy group that satirizes religious orders for the purpose of LGBT activism. The organization is a parody “order” of gay male “nuns” dedicated to “the expiation of guilt.” 
The Sisters of Perpetual Indulgence fundraise through performances where they dress in drag, often in the form of a parody catholic imagery. Their signature fundraising event takes place on Easter Sunday, a high holiday for Christians, which includes a “Hunky Jesus Contest.”  Funds from such events are used to issue grants to LGBT advocacy organizations.
The Sisters of Perpetual Indulgence was founded in 1979 by four gay men who dressed in nuns’ habits in full drag and performed theatrical acts throughout the city.  Michael Williams, one of the founders of the organization and known by the stage name “Sister Roma,”- claims that SPI pioneered activism in drag or “dragtivism.”  The organization continued to support LGBT causes throughout the 1980s and in 1989 became a 501(c)(3) non-profit organization, allowing it to receive tax-deductible dollars and engage in educational activities to further its mission of supporting LGBT interests. 
In 2007, the Archbishop of San Francisco, George Niederauer, issued a public apology to the Roman Catholic community after he delivered the Eucharist to two individuals affiliated with the Sisters of Perpetual Indulgence. The affiliates resembled nuns and were dressed in drag. The apology acknowledged that it was a mistake for them to receive the Eucharist, referencing the organization’s longstanding mockery of the Catholic Church, and religious women in particular; commenting that he found their presence to be a mockery of the church and offensive. 
In 2017, Westcott House in Cambridge, U.K. chose to celebrate LGBT history month. While the Church of England had allowed for services to take place to commemorate LGBT history, a minister at Westcott house overstepped the invitation by conducting an evening service entirely in Polaris-a form of Queer slang-based on a translation of the Bible written by the Sisters of Perpetual Indulgence. Some members of the church found the service highly objectionable, such as a part where the traditional “Glory be to the father, and to the son, and the Holy Spirit” was translated as “Fabeness be to the Auntie, and to the Homie Chavvie, and to the Fantabulosa Fairy.” This controversy led to the Rev. Canon Chris Chivers, the principal of Westcott House, formally apologizing for the incident. 
In 2019, the Sisters of Perpetual Indulgence participated in London Pride, rebranding themselves as “The Imams of Perpetual Indulgence,” advocating for LGBT positions while denouncing anti-LGBT attitudes in Islam. The social media response to the event was polarized, with some condemning their general conduct and mocking of the Islamic religion. 
In 2019, the Sisters of Perpetual Indulgence created an event titled “Drag Queen Story Hour,” to be held in a public library in Simpsonville, South Carolina. The event prompted a petition asking the library to prevent men dressed in drag from interacting with children in public space funded by tax dollars. A representative of the Sisters of Perpetual Indulgence, Natalie Shaik, defended the event, stating that it is designed for parents who want to expose their children to “different kinds of people.” 
The Sisters of Perpetual Indulgence was founded by Bobbi Campbell, Ken Bunch, Fred Brungard, Edmund Garren, and Bill Graham.  Today the organization claims branches in 10 countries, with offices and presence in over 25 states. 
The Sisters of Perpetual Indulgence fundraise through donations received at their events and ceremonies. Over the last 20 years, the organization has raised $1.5 million to further its mission.  In 2016, the organization received $135,459 in contributions and spent $154,130 on functional expenses.  Examples of organizations the Sisters of Perpetual Indulgence have financially supported include the Center for Immigrant Protection (The LGBT Asylum Project), San Francisco Dyke March, and the Trans Liberation Coalition.
