Diatribe? Oh well, let that pass. The validity of a priest's orders is not tied to his personal sanctity or personal orthodoxy. I am not trying to imply here that your priests lack sanctity.
A priest can be a heretic, but his orders are still valid. A priest can be in mortal sin, but his orders are still valid. I am not trying to imply here that your priests are in mortal sin.
In fact, the Catholic Church recognizes some Anglican priests as having valid orders. It is a matter of whether they have apostolic succession, not a matter of whether or not they are correct in their dogma. I am not trying to imply here that your priests are as bad as Anglican priests.
