At the site of the Ordinariate Portal there is a photo of one of the former Anglican Bishop saying his first Mass. He is, of course, now a Catholic priest.
Fr. Andrew Burnham said Mass for the first time at the Oxford Oratory.
Note the Benedictine Arrangement of the altar.

WDTPRS kudos to Fr. Burnham.
And Benedict XVI is the Pope of Christian Unity.
