How Jehovah's Witnesses are changing medicine

In the Book of Acts, the apostle Paul urges congregants to abstain "from things sacrificed to idols, from blood, from what is strangled, and from sexual immorality." Jehovah's Witnesses, apparently alone among Christian groups, believe this verse, along with others, prohibits them from accepting blood transfusions, no matter how dire the circumstance. As Joan Ortiz, a Witness in her sixties, recently told me, it's as much a sin to take a blood transfusion as to have an extramarital affair. In this interpretation of Scripture, those who comply will prosper and enjoy good health.
