This has never been done and, of course, that’s the point.
The Pope has been trying to get women in the Vatican for years—remember his 2014 nomination of Sr. Irma Luzia Premoli as a member of the Congregation for the Evangelization of Peoples? That was the first time a superior general of a female institute was named a member of a congregation.
And it gets even worse better. After the precedent set on July 8, Curial positions are open to persons not ordained as priests… think about that for a moment.
Francis is a busy man! And if he can just appoint some openly gay bishops his job will be done here and, just 54 years after the close of the Second Vatican Council, the fat lady can finally sing.
