There is story that the former Bishop of Fulham, who was recieved into the Catholic after the ordination of women to the priesthood in the C of E, left his mitre behind for his successor. After wearing it for a few months, he looked inside and found written, "absolutely ..... null and totally .... void", it is quote from Leo XIII's judgement on Anglican orders.
After the revision of the Prayer Book the C of E sought to answer this by including Old Catholics in their Episcopal Ordinations. For example, Graham Leonard, the former Bishop of London was ordained a Catholic priest conditionally because it seemed that several of his consecrators as an Anglican bishop had valid orders.
In the Preface of Apostles, in English, there is the phrase, "... from their place in Heaven the guide us still". My concern has always been that "being Apostolic" has as much to do with fruit as it does with root. I mean for example, none of those Churches which we consider as Catholics to be Apostolic have ordained women. Apostolicity is about the past, the root, but it is also about the present, the fruit. Christ promises to be with his Church, which he built on the Apostles, until the end of time, well, we need then to look for the evidence of that.
