With much that is truth there is mingled error that is accepted in its extreme meaning, and acted upon by persons of excitable temperament. Thus fanaticism will take the place of well-regulated, well-disciplined, heaven-ordained efforts to carry forward the work to its completion.... 2SM 17.2
There is danger, not only that unbalanced minds will be led into fanaticism, but that designing persons will take advantage of this excitement to further their own selfish purposes.... 2SM 17.3
I have a warning to give to our brethren, that they shall follow their Leader and not run ahead of Christ. Let there be no haphazard work in these times. Beware of making strong expressions which will lead unbalanced minds to think that they have wonderful light from God. The one who bears a message to the people from God must exercise perfect control. He should ever bear in mind that the path of presumption lies close beside the path of faith.... 2SM 17.4
Once let impulse and emotion get the mastery over calm judgment, and there may be altogether too much speed, even in traveling a right road. He who travels too fast will find it perilous in more ways than one. It may not be long before he will branch off from the right road into a wrong path. 2SM 17.5
Not once should feeling be allowed to get the mastery over judgment. There is danger of excess in that which is lawful, and that which is not lawful will surely lead into false paths. If there is not careful, earnest, sensible work, solid as a rock in the advancement of every idea and principle, and in every representation given, souls will be ruined.—Letter 6a, 1894. [For fuller context see pages 90-92.] 2SM 18.1
