The C&MA affirms the permissibility of blood transfusions for medical purposes. Unlike the Jehovah's Witnesses, who prohibit transfusions based on Old Testament food laws (Leviticus 17:10-14), the C&MA understands these laws as ceremonial regulations of the Mosaic covenant that do not bind Christian conscience. The prohibition was against consuming blood (eating), which had sacrificial and ceremonial significance; receiving blood medicinally for the purpose of saving life is a different matter entirely.

The C&MA affirms the value of medical care as a legitimate means of healing and maintaining health. While also affirming prayer for divine healing, the C&MA does not teach that believers should refuse medical treatment in favor of faith alone. God works through many means, including medical science. Physicians and modern medicine are gifts of God's providence, and using them is consistent with Christian faith and responsibility for one's health and the well-being of one's family.

This position reflects the C&MA's broader affirmation of divine healing as available in the atonement while recognizing that God often works through natural and medical means. A believer who receives a blood transfusion is not violating biblical law or committing sin. Individual Christians may exercise their conscience in these matters, but the C&MA does not prohibit transfusions or regard them as unbiblical.
