Shortly after she got her high school diploma in Hof, Bavaria in 2003, she joined the new spiritual community (movimento) Geistliche Familie „Das Werk“ [de] (FSO "The Work") and worked for a few years in the community house in Rome.
On November 11, 2007, she made her promises (Heiliges Bündnis in den drei evangelischen Räten, "Holy Covenant in the three evangelical counsels"), in the Roman church Santa Maria in Traspontina in presence of the Archbishop of Bologna, Carlo Caffarra.
In 2008, aged 24, Reisinger alleged she was sexually assaulted by Austrian priest Hermann Geissler, a member of both "Das Werk" and the Congregation for the Doctrine of the Faith.

Reisinger criticised that in her opinion hierarchies of many religions and faith communities, such as the Catholic Church, subordinate individuals.
