There is no means by which one might justify that within Catholic or Anglican theology. What's the source for this allegation, beyond "I was told"?

Have you heard of a book called 'Holy Sh*t: A Brief History of Swearing'? The author talks about this belief, but she claims it was in the Middle Ages, not the 19th Century. Swearing vain oaths using parts of God's body was common---i.e. 'by the blood of Christ' or 'by God's nails', that sort of thing, and some religious authorities believed that when someone swore 'by God's nails' they were literally ripping the nails from his hands and causing him physical pain. The author references a number of tracts which warn people that vain swearing on God's body parts was grounds for terrible divine punishment, because they were causing God pain over trifling matters.

I apologize I cannot remember any more details than that from the book but it might be where your questioner got the idea. I also do not know enough about the Middle Ages to know if the author's assertions are accurate or not---I'd be interested what an expert on the medieval period thinks about it.

Here is the book in question.
