(Mind, Character, and Personality Volume 1 192.1)
I must state to you that I have been shown that the best methods have not always been practiced in dealing with the errors and mistakes of students, and the result has been that souls have been imperiled and some lost. Evil tempers in the teachers, unwise movements, self-dignity have done a bad work. There is no form of vice, worldliness, or drunkenness that will do a more baleful work upon the character, embittering the soul, and setting in train evils that overbear good, than human passions not under the control of the Spirit of God. Anger, getting touched [being aroused], stirred up, will never pay. (1MCP 192.1) MC VC
