Another ‘miracle’ comes crashing down amongst the flames of facts, examination and research:

Blood of Christ? Not so much.
Infectious bacteria? Yep

Serratia marcescens is a bacteria that has earned a bad reputation for infecting people in hospitals. It may deserve an even worse reputation. It might have made people believe, for hundreds of years, that the blood of Christ was miraculously appearing in communion wafers.

  1. Deborah – you might find this fascinating. No transsubstantiation – just spoiled bread and a happy bacteria. This also seriously compromises the claims of the Argentinian miracle host that was allegedly analyzed to reveal ‘human dna’ – ie someone was lying.

  2. The second link is quite fascinating, as it includes actual debunking and analysis of ‘miracle blood’.

  3. That’s the one I was referencing. Argentina. Priest leaves a host in the cup and the sacred cupboard. Humidity and dark damp environment interact. Sees a couple of weeks later that a reddish fleshy substance has accumulated. Freaks out and thinks it’s the blood and flesh of christ Christ.

  4. Two possibilities – our friendly bacterium, and someone is lying; someone in the church bled on the item (or the priest had a cut on his finger) which accounts for the DNA.

  5. I’m very familiar with the article. I’m also very familiar with the fact that this highly biased source seems to be the only source for this ‘miracle’

  6. This would be relatively easy to lay to rest with modern DNA analysis. Check if the flesh and blood in buenos aires or Lanciano is of Arab or middle eastern origin. Conveniently, this sort of analysis is not allowed – while a DNA analysis that verifies ‘suffering’ is somehow possible (wtf?)

  7. Isn’t it strange that the hundreds of other ‘sources’ of this miracle all reference the same LOA original,source? You would think that such a ‘true miracle’ would have other, additional, sources that either write about it, analyze it, etc… Unless, of course, it’s a fake.

  8. Peruse that thread. Particularly the observation that this ‘miracle’ is not known anywhere in argentina (where cults spring up around lesser ‘miracles’ is indication enough to me that this entire story is a hoax aimed at the gullible who WANT to believe. Add to it that dates and names are incorrect in the article… Well, draw your own conclusion.

  9. “Her cancer is gone” – doubtful on many levels. Without knowing ANY additional details about this case (ie what cancer did she have; was she receiving any real medical treatments? Etc). It’s not a miracle if she was receiving legitimate treatment and her cancer went into remission from that.

  10. on the other hand, what this might do is make her reject and follow-up treatments or checkups. Which could have fatal consequences.

  11. … a friend of mine went through some liver cancer treatment, including surgical removal. After his follow-up checkups, there was a big family party, with everyone loudly praising and thanking God for healing him. I earned scornful glances by speaking up and reminding everyone that, just maybe, the surgical team, the hospital, and his doctors might deserve just a tiny bit of thanks and praise as well. I really, really hate superstition, particularly when it takes away well deservd credit from real people.

  12. See, that’s the problems with such ‘local miracles’ – most of them are hearsay, and no one wants to dig any deeper. Would you apply the same lack of questioning to, say, your own surgeon, or someone asking you for a loan?

  13. The shroud? Of Turin? Well proven to be a fake by now, unless Jesus had a time machine and was buried 1400 years later 😉
