The Instruction on Summorum Pontificum called Universae Ecclesiae, in paragraph 28, excludes service at the altar by females for the Extraordinary Form.
You will recall that the chaplain at the University of Cambridge’s Fisher House, Fr. McCoy, decided to have celebrations of the Extraordinary Form of Mass with service at the altar by female servers.
A one time event at Cambridge?
I received this today:
I regret to tell you that the Chaplain of Fisher House, University of
Cambridge, said a Mass in the Extraordinary Form this evening and once
again used female altar servers, despite paragraph 28 of Universae
Ecclesiae. Can I please ask for your prayers that Fr McCoy may be made
to see the pain and hurt that his actions are causing. I also ask you
to pray for him.
The Pontifical Commission “Ecclesia Dei” has competence in this matter. If there is a conflict about the provisions of Summorum Pontificum or the points of Universae Ecclesiae which have the force of law (paragraph 28 is one of them), then the PCED will have to make some ruling.
Pray for those involved.
