The Gospel is Calculated to Cause Division

The Gospel of salvation is perfectly calculated to cause division. It strikes at the root of the very existence of mankind in their wickedness, evil designs, passions, and wicked calculations. There is no evil among the human family, but at the foundation of which it strikes effectually, and comes in contact with every evil passion that rises in the heart of man. It is opposed to every evil practice of men, and consequently it disturbs them in the wicked courses they are pursuing.     
Whenever the Gospel is preached in towns, cities, country places, or in any community who are in darkness, it never fails to bring light; it manifests their ignorance; it distracts them, and annoys their peace. They say, "I supposed I was wise, happy, comfortable, and well enough off; but here comes something that informs me I am mistaken, that this and the other thing are wrong. It reflects light upon my understanding, and teaches me that my acts, while I live upon the earth, should tend to the glory of God and the peace of mankind. This naturally seems contrary to my feelings, disposition, passions, and traditions, and to every thing about me, except the reflection of truth upon my mind, which enlightens my understanding, and teaches me to glorify God, and do good to my fellow creatures."  Brigham Young; General Authorities, Journal of Discourses v1, Discourse By President Brigham Young (6)
