No doubt people have given an unnecessary and excessive importance to the personality of the messenger rather than to the message, and this is the very great error that humanity has made in every age. In taking the messenger instead of recognizing the message, they regarded the pen that wrote the letter instead of the contents of the letter. The letter and the writer are important; the pen is only the instrument. Thus differences came about in religion. The message has always been given at all periods; when it was more needed it was given with a loud voice, when it was less needed, gently.
