Bloodletting – Life Is In the Blood

Bloodletting – Life Is In the Blood

For almost 2000 years, from ancient Greece to the nineteenth-century, the most common procedure performed by surgeons was bloodletting. The doctors would cut the patient to allow blood to drain because they thought this would drain disease from the body. In truth, if it didn’t kill the patients, bloodletting at least left them weaker. The medical establishment didn’t realize that life is in the blood.

Even though William Harvey disproved the effectiveness of bloodletting in 1628, doctors (and barbers) still practiced it for another 200 years. It can take a long time for false ideas to be abandoned, even by doctors and scientists. In some areas such as China and the Middle East, people still practice a form of bloodletting today known as hijama or cupping.

While they were still practicing bloodletting, doctors began to experiment with blood transfusions. Early experiments in the seventeenth-century involved transfusions of animal blood into humans, usually with disastrous results. Doctors didn’t realize that there are different blood types among humans and even among animals. Different blood types have a different molecular structure in the red blood cells. If a patient is given blood of the wrong type, it can cause a reaction that can be fatal, because the patient’s immune system attacks the foreign blood cells as invaders.

In 1901 Karl Landsteiner found that mixing blood from different patients sometimes caused clotting. This led him to classify blood into three types—A, B, and O. Scientists have discovered more blood groups since then, making transfusions much safer today.

If those who practiced bloodletting had paid more attention to the Bible, they might have realized much sooner that it was a bad idea. “The life of every creature is in the blood” is stated twice in Leviticus 17 verses 11 and 14. With that admonition, God commanded the ancient Israelites to refrain from eating blood and to sacrifice the blood of animals to cover their sins. But the final redemption for sins came when “God presented Christ as a sacrifice of atonement, through the shedding of his blood” (Romans 3:25). Life is in the blood, and eternal life is in the blood of Christ.

Eating Blood: Is It Moral and Wise?

Eating Blood
We have received several questions about whether Christians should practice drinking or eating blood, eating afterbirth, or injecting or eating animal hormones. This goes back to Genesis 9:3-4 where God told Noah not to eat blood, and the prohibition about eating blood continues throughout the Old Testament (See Leviticus 17:10-11). In the New Testament, we see a prohibition about eating blood in Acts 15:20-29.

There are two different things involved here. One is the question of religious significance, and the other is what is hygienically wise. In the Old Testament blood was a major part of the daily religious life of the Israelites. To offer blood as a sacrifice for sin was to “give up life” for sin, and thus eating blood was a form of idolatry. It was like saying that God was not needed as the life giver and that the eater had power over life. In Acts 15:20 the restriction of not eating blood was included with “abstaining from the pollution of idols” for the reason of the connection to idolatry.

The hygienic issue of eating blood should be obvious. Any disease an animal had could be passed on through the animal’s blood. The warning against eating a thing strangled (Leviticus 17:13-16 and Acts 15:20) was because the blood remains in the flesh instead of being drained out as in the practice of butchering. When Paul wrote to the Christians in 1 Corinthians 10:23-33, he advised them when having a meal with an unbeliever, “…whatever is set before you, eat, asking no question.” But then he goes on to point out that Christians must be concerned about how their choices affect others.

In today’s world, we may have hygienic reasons for not eating something, but food prohibitions are not a part of the teachings of Jesus or His apostles.
