If Songbird understood the teaching of Pope Leo XIII and the history of the ordination rite, he/she/it would know that the the new rite of ordination is valid.
Michael Davies’ book “The Order of Melchizedek” was always a bit of a mystery to me in this regard:
He repeatedly affirms the validity of the new rite, even as he draws, throughout the book, the analogy to the invalidating changes to the Anglican rite.
It always left me asking myself, “OK, so why bother to write the book?”
And if the answer were, “To put traditionalists at ease regarding the new rite,” then why trouble them by drawing the Anglican analogy (which is the general disturbance of soul produced by the book, despite Davies’ affirmation of validity)?
Again, why, then, bother to write the book?
Was he being coy, fearing to declare the rite invalid, but imparting to the reader the reasons it might be (despite his affirmation to the contrary)?
Not sure.
