Input: Jehovah's Witnesses refuse blood transfusions, which they consider a violation of God's law based on their interpretation of Acts 15:28, 29 and other scriptures. Since 1961 the willing acceptance of a blood transfusion by an unrepentant member has been grounds for expulsion from the religion. Members are directed to refuse blood transfusions, even in "a life-or-death situation". Jehovah's Witnesses accept non-blood alternatives and other medical procedures in lieu of blood transfusions, and their literature provides information about non-blood medical procedures.
Output:
What biblical passage informs Jehovah Witnesses' refusal of blood transfusions?
