As society seeks a solution to the current pandemic, including immunity from contagion, Christian Scientists willingly abide by any legal requirements. They do so in a spirit of neighborly love for others. 

However, Christian Science emphasizes the mental nature of what we experience. So while medical researchers look to the material body as the site of the problem and to a vaccine as a solution, followers of the Science of Christ identify matter-based thought as the cause of disease, and God-impelled thought as the cure, thereby following the biblical teaching that says of a man, “As he thinketh in his heart, so is he” (Proverbs 23:7). Whatever we accept in consciousness as our own thinking will sooner or later be made manifest in our experience. Hence the necessity not to admit into our consciousness anything that would belittle or deny the nature of God, good, and consequently, our own.

In the Christian Science textbook, Mary Baker Eddy points out the underlying mental nature of disease when she writes about the need to exterminate “all the mental microbes of sin and all diseased thought-germs” (Science and Health with Key to the Scriptures, p. 164). Whether unintentionally or deliberately, we invite in “diseased thought-germs,” or error, by hosting fearful and sinful thoughts in our consciousness.
