Australian scientists discovered the cause of a mysterious disease that had killed thousands of Tasmanian Devils on the island state of Tasmania. The scientists initially believed the deaths were caused by a virus; however, their research ultimately uncovered a rare, fatal cancer. They named it Devil Facial Tumor Disease, or DFTD.

What is strange, according to cytogeneticist Anne-Marie Pearse, is that the abnormalities in the chromosomes of the cancer cells were the same in every tumor. That means the disease began in the mouth of a single, sick devil. That individual facilitated the spread of DFTD by biting its neighbors when squabbling for food, which, according to Pearse, is a natural devil behavior: "Devils jaw-wrestle and bite each other a lot, usually in the face and around the mouth, and bits of tumor break off one devil and stick in the wounds of another."

Over the course of several years, infected devils continued to inflict deadly wounds with their mouths. Consequently, DFTD spread at an alarming rate, ultimately wiping out over 40 percent of the devil population.

A similar fate threatens the Church if its members persist in the devilish behavior of wounding their neighbors with their mouths.
