This whole thread has been rendered moot, by the revelation that Fr. Arrizaga received his holy oils from Fr. Hewko (who himself has not received any from +Zendejas for years, if ever).
The integrity of the oils would be suspect after so long a time, thereby making the matter suspect, and the sacrament doubtful from this cause alone, even if all Fr. Arrizaga’s arguments were conceded (which they aren’t).
