So if some Anglican preacher claims there was a Eucharistic miracle (before the "miracle" is confirmed by the Anglican church, never mind the Catholic church) then we should immediately accept it as a miracle that confirms the validity of the Anglican service?
I'm still skeptical, but if it was your run of the mill Church of England priest (ie. holy orders tainted by the line of Edward VI) I'd *definitively* disbelieve it because I don't see *any way* those priests could be valid, just by sheer logic.
If you're talking about some Anglican priest who got his orders from Old Catholics (I've heard this is the case for Continuing Anglicans, which I believe would be where that alleged Eucharistic miracle took place) I'm still certainly skeptical, but such orders could be valid without contradicting Leo XIII
