Regarding the Holy Water experiment itself:
Without source documents, publication, and peer review the photos will not pass as scientific evidence to convince my agnostic friend. I intend to follow up with St. Mary's Assumption Church, though I do not expect much. Even if the photos somehow pan out as true, it will not actually be proof of God's existence, but would show that prayers could create effect in the physical realm, and thus serve to demonstrate to my friend that there is more to Christianity than mere mythology; and would give him something to think about.
I asked about this specifically because several years ago, the movie "What the *Bleep* Do We Know" came out, and in it, an experiment was cited, and if memory serves, re-created. A scientist (Dr. Masuro Emoto) took flasks of distilled water and had people (off the street, not clergy) curse at one and 'project anger and negativity' at it. Upon the other, he had people 'project their happy thoughts' (all very 'new age', I know). The water from each vial was then simultaneously frozen and the crystal formations compared. The crystals in the first were deformed and in the second were natural and beautiful. (again, I am going on memory). Here is out take from the movie, showing some of Dr. Emoto's results:http://www.youtube.com/watch?v=zpnlCo5APrE
At the time my daughter was in High School and was looking for a project for a science experiment. We discussed performing a similar experiment as the movie had shown but using Holy Water from RC, EO, and other; plus control group, etc. All would be in accordance with scientific standards. No matter what the results were, the experiment, we felt, would be a shoe-in for publication and would certainly stir up controversy. If you are in High School and looking for scholarship money, publication and controversy are good, very good indeed!
But we also considered, as cited above Matthew 16:4, and Matthew 4:7 "Do not put the Lord your God to the test" (NIV); and Matthew 16:26 'what is a man profitted, if he shall gain the whole world, and lose his own soul?". We prudently decided not to pursue the idea.
But, when Psadi97 mentioned the Holy Water under the microscope, it sounded like someone else had the same idea. It wouldn't surprise me if an atheist had attempted such an experiment as a disproof. So, I was curious about the results and had to inquire further.
Sorry to create such a stir!
