“The body is one unit, though it is made up of many cells, and though all its cells are many, they form one body. . . . If the white cell should say, because I am not a brain cell, I do not belong to the body, it would not for that reason cease to be part of the body. And if the muscle cell should say to the optic nerve cell, because I am not an optic nerve, I do not belong to the body, it would not for that reason cease to be part of the body. If the whole body were an optic nerve cell, where would be the ability to walk? If the whole body were an auditory nerve, where would be the sense of sight? But in fact God has arranged the cells in the body, every one of them, just as he wanted them to be. If all cells were the same, where would the body be? As it is, there are many cells, but one body.”
