There is no unbroken line of ordained bishops and priests traceable back to St. Peter. This is simply confusing the symbol for the thing symbolized.

There is no unbroken line of ordained bishops and priests traceable back to St. Peter by the automatic conferral of grace by the tactile laying-on-of-hands. The succession the Bible teaches is the succession of apostolic teaching from the Apostles to all subsequent generations to the end of time - the passing on of the catholic faith once and for all delivered to the saints (Jude 3; 2 Tim 2:2).

Cranmer did not believe that the apostles passed down the Holy Spirit through an unbroken line of holy bishops like a pipeline. No, for Cranmer, the author of the founding formularies of Anglicanism, apostolic succession meant the passing down of apostolic teaching.
