The RCA affirms that blood transfusions are permitted and do not violate biblical principles. The Old Testament laws against consuming blood (Leviticus 17:10-14) are understood as ceremonial laws binding specifically to Israel's covenant observances. These laws do not extend to modern medical transfusions.

The rationale is that consuming blood in violation of the ceremonial law caused ritual defilement under the Mosaic covenant. Modern transfusions involve infusing blood into the circulatory system as a medical treatment, not consuming it as food. The principle underlying the law (respect for blood's symbolic significance in sacrifice) is not violated by therapeutic transfusions.

The RCA opposes the Jehovah's Witnesses interpretation and affirms believers' freedom to accept transfusions as needed. Preserving health and life through medical means honors God and reflects proper stewardship of the body.
