If she continues with her activities, which violate Catholic teaching, and which the Church authorities have repeatedly called on her to stop, couldn’t she potentially face excommunication?
The problem isn’t individual, it is systemic:
from Sisters of Loretto website:
"In the Loretto tradition of ‘working for justice and acting for peace,’ the saints and heroes who struggle for equality and conscience were called to mind as well.
In the political and legal realm, those gathered
sang the names of John Lawrence, plaintiff in the case that decriminalized same-gender consensual sex, as well as President Barack Obama and Attorney General Eric Holder, who have refused to enforce the Defense of Marriage Act.
"In the ecclesiastical realm, theologians Hans Kung, Charles Curran, and Margaret Farley were sung at the Vatican Embassy for their progressive views on human sexuality and the Vatican censures that followed. Bishop Thomas Gumbleton was intoned at the USCCB for his outspoken voice for LGBT rights within the Catholic Church.
Fittingly, Sr. Jeannine was included in the litany, along with several other women religious. The program described Sr. Jeannine in the following way:
“Loretto Sister who advocates for LGBT persons in the face of continual Vatican opposition.” (end quote, bold added)
The Sisters of Loretto are now rebranded as the Loretto Community, to broaden their financial and political base. They still bring in lots of Catholic donations, tuition, and other fees from their programs. They get lots of free publicity from diocesan newspapers, parish bulletins, etc. Laity can contact donors or other persons who support them or give them or their schools free publicity. Let them know that supporting the Loretto directly or indirectly is an attack on prolife.
