In working out problems in Christian Science, controlling one's tongue has a most important place.
When some discordant situation crops up, one may at first be inclined to believe it. Often he is tempted to tell another and does so without a useful purpose. The trouble is still only a false belief, but now it can be regarded as compounded. The patient has no direct control over what the second person may say, so it may too easily be spread further.
It may, of course, be necessary and desirable to tell another, such as a Christian Science practitioner who is being asked to give treatment, or someone else who can be relied upon not to accept the error but set about rejecting it altogether and will certainly not mention the difficulty to others. Also, the law of the land may require one to notify the authorities of a communicable disease.
