Calvary Chapel has no prohibition on blood transfusions or other standard medical interventions. Medical care is viewed as a gift of God's common grace, and accepting transfusions poses no theological concern. The movement's mainstream evangelical theology does not assign religious significance to blood in a way that would prohibit transfusions.

Calvary Chapel encourages believers to care for their bodies and to use available medical resources responsibly. Occasional teachings on divine healing do not translate into a prohibition on conventional medicine; prayer and medicine are seen as compatible.
