Much discussion has surfaced about the excommunicated nun, Sr. Margaret McBride, for assisting in the 2009 abortion at St Joseph’s Hospital, Phoenix, AZ.

Canonist Edward N. Peter’s wrote a piece on his blog, In the Light of the Law, “Toward clarifying the canonical status of Sr. Margaret McBride.”
I think Dr. Peter’s is clear. Don’t you?
