One of the most frequent objections of the opponents of Christian Science is, that Christian Scientists are narrow because they are trying to live according to a definite rule; but is it narrow to follow a principle in any given work, avoiding all such things as must necessarily conflict with that principle?

The navigator of a vessel follows the indications of his compass absolutely if he be an honest man and truly desirous of bringing his charge safely to her destination. He knows that delay must, and disaster may, result from the slightest deviation from the right course, yet the whole wide ocean lies before him, and he can if he chooses go thousands of miles out of his way and be "free."
