I’d settle for some scientific lab analysis.
Forensics departments around the country ought to be able to handle that well enough. They have plenty of methods for determining human blood and type.
A lab report would be nice.
I’m assuming everyone who is involved in this part of the “discussion” will see it so I’m not going to go ping happy.
From the old Catholic Encyclopedia online:
Strictly speaking transubstantiation is not a miracle.
Beyond that someone asked when the Roman Church reintroduced the Chalice to the laity. In theory this was an effect of the Second Vatican Council although it had occurred illicitly from time to time before the liturgical reforms of the Pauline Missal. Communion under one kind is/was a disciplinary practice of the Latin Church enacted as part of the liturgical reforms that flowed from the Council of Trent for the explicit purpose of combating heretical opinions of something called an Utraquist (some sort of Hussite I gather).
Actually the post conciliar documents still assume that Holy Communion will be administered under the species of Bread alone except for certain special celebrations. I think that was superseded sometime after I stopped paying attention to the post-post conciliar reform of the reforms of the reform. For all practical purposes Communion has been under both kinds in the Latin Church since the mid 1960s/early 1970s. The other ritual Churches have used some form of intinction (the priest dipping the consecrated Bread in the Chalice) all along though.
There’s a huge article at the old Catholic Encyclopedia site under the entry for “Communion under both kinds”... I mean HUGE HUGE.
Wouldn't you rather place your fingers in the wounds?
There you go...
