The orders of the above three Anglican bishops were not valid and were not recognized as such by anyone in the Vatican. John Paul II kissing an Anglican’s ring is no more a validation of his orders than kissing a Qur’an is a validation of its contents.
Pope John Paul II kissed the ring that Pope Paul VI had given to the the faux bishop, Michael Ramsey; thus recognizing both Rowan Williams and Ramsey’s “valid”orders.
It wasn’t an “anglican ring”! It was a Catholic episcopal ring given by Pope Paul VI to the heretic, Michael Ramsey.
