Which religious affiliation includes beliefs against blood transfusions?

The belief against blood transfusions is primarily associated with Christian Scientists. This religious group holds specific interpretations of the Bible that influence their health practices, including a reliance on prayer for healing rather than conventional medical interventions. They interpret certain biblical passages as prohibitive of ingesting blood in any form, which extends to blood transfusions. This distinctive approach to health and healing reflects their broader theological commitment to spiritual over physical interventions.

In contrast, the other groups listed—Seven-day Adventists, Methodists, and Baptists—may have various health guidelines or lifestyle practices, but they do not generally have prohibitions against blood transfusions. Seven-day Adventists advocate for a healthy lifestyle, which includes vegetarianism but do not reject medical treatments like transfusions. Methodists and Baptists follow mainstream medical practices and do not have doctrinal teachings that oppose blood transfusions.
