A Witness in Colorado worked in a hospital as the chief medical technician running tests of various types on body tissue and fluid. Among the many things he was expected to test were blood samples. Sometimes it was simply to check a patient’s blood for the level of sugar or cholesterol. But at other times it was to cross match for transfusion purposes. Could he do that?

⁹ This Christian gave careful thought to the matter. It could be seen that it would not be right for a Christian to work exclusively for a blood bank, where everything was devoted to an end that was in violation of God’s law. But that was not his situation; he ran tests of many kinds. Also, if one were a doctor responsible for the decision, one could not order a blood transfusion for a patient, any more than a Christian store owner could order and stock idols or cigarettes. However, this technician realized that in connection with blood he was merely running a test, even as a nurse might have taken the sample, a messenger might have delivered it to the laboratory and someone else might administer a transfusion or other medication on a doctor’s orders. He reflected on the principle at Deuteronomy 14:21. According to that text a Jew finding a carcass of an animal that died of itself could clear it away by selling it to a foreigner who was not under the Law’s restrictions about animal flesh not drained of its blood. So the technician’s conscience at that time allowed him to run blood tests, including those of blood for transfusions to patients who did not care about God’s law on blood.

11. How did conscience move this same Christian many years later?

¹¹ In this particular case, after many years of running tests, the technician began to be troubled by his conscience. It was not as if someone else should or could tell him that he was doing wrong. Nor was he looking for someone else to make his decisions for him. But he began to think: “Is it consistent to talk of neighbor love, and yet contribute, in part, to my neighbor’s breaking of God’s law?” (Matt. 22:39; Acts 21:25) Appreciating his Christian duty to support his family, he discussed the matter with his wife. (1 Tim. 5:8) Together they agreed that, if his conscience was troubled, it would be better to make a change. He left his $15,000-a-year job and began doing cleaning work, though he started off earning just $3,600 a year.

12. Does this mean that his earlier decision was wrong, or just what is illustrated by this case?

¹² Let us not miss the point of this example. It is not related here to suggest that a Christian cannot be a medical technician; there are Christians who continue to work as medical technicians, nurses, truck drivers, and so forth. This example is given to illustrate that conscience can come into play on matters of employment. In your case the type of job and what you are asked to do may be quite different. But all Christians should give thought to whether they are living as closely as possible in accord with God’s ways and principles.
