The RCCG has no doctrinal prohibition on blood transfusions. Modern medical procedures, including blood transfusions, are understood as permissible within the framework of Christian stewardship of health and medical care. The church does not teach that the biblical prohibitions on consuming blood (Acts 15:29) extend to medical blood transfusions. The saving of life and the promotion of health are understood as paramount Christian values.

The church's theology of the body and health emphasizes divine healing through prayer and faith, but does not reject medical science or medical interventions. Believers are free to receive blood transfusions when medically necessary, and the church does not consider this a violation of biblical law or Christian principle. The RCCG operates hospitals and medical clinics in Nigeria and other regions, reflecting the church's commitment to holistic healthcare.
