Some thought the same about TA's understanding of human conception. Alas, he turned out to be wrong.
Aquinas would no doubt disapprove of "Communion Services in the absence of a priest or deacon," but they are a reality and a necessity in today's Church.
The particular citation was well within TA's area of competence--unlike embryonic biology, still a developing science.
TA would most likely approve of communion services in cases of necessity--like all men of the Church of Common Sense (that's the one we call Roman Catholic) TA never would allow the lesser to overcome the greater.
But "necessity" is rather elastic for priests who think they have a Job, not a Vocation.
"Aquinas would no doubt disapprove of "Communion Services in the absence of a priest or deacon," but they are a reality and a necessity in today's Church."
Nonsense. We could just not do it.
