A consecrated Host became flesh and blood in Buenos Aires, Argentina in 1996. Father Alejandro Pezet was saying seven o'clock mass at a Catholic Church in Buenos Aires. A woman told him she had found a discarded Host on a candleholder in the back of the church when he was done distributing Communion. Father Alejandro wasn't able to consume the Host, so he placed it in water, then put it away in the tabernacle. He opened the tabernacle on Monday, August 26, and found that the Host had been transformed into a bloody substance. On September 6, the transformed Host was photographed as per Cardinal Jorge Bergoglio's instructions. The Host remained in the tabernacle, hidden in secret for years. It was not until October 5, 1999 that it was sent to New York for scientific analysis. The scientists were specifically uninformed of the source of the piece of flesh to prevent any bias. Dr. Frederic Zugiba was a well known cardiologist and forensic pathologist. It was determined that this material was human flesh and blood containing human DNA. It turned out to be a fragment of the heart muscle found in the wall of the left ventricle close to the valves. It's responsible for the contraction of the heart, and it is the left side of the heart that pumps blood to the rest of the body. The muscle was in an inflammatory condition and contained a large number of white blood cells. This shows that the heart was alive at the time of the sample was taken because white blood cells can only survive inside a living organism and scientifically should have died in a matter of minutes in the conditions they were kept in. The white blood cells had also penetrated the tissue, giving further indication that the heart had been under a lot of stress and the owner had taken a severe beating to the chest. The doctor was amazed once he heard about the source of this flesh. Nobody has any scientific explanation as to how the Host was transformed and preserved for so long.
