Contend against No One; Speak the Truth in Soberness
Doctrine and Covenants 18:20–21
20 Contend against no church, save it be the church of the devil.
21 Take upon you the name of Christ, and speak the truth in soberness.
The Prophet Joseph Smith said:
“Let the Elders be exceedingly careful about unnecessarily disturbing and harrowing up the feelings of the people. Remember that your business is to preach the Gospel in all humility and meekness, and warn sinners to repent and come to Christ. Avoid contentions and vain disputes with men of corrupt minds, who do not desire to know the truth. Remember that ‘it is a day of warning, and not a day of many words.’ If they receive not your testimony in one place, flee to another, remembering to cast no reflections, nor throw out any bitter sayings. If you do your duty, it will be just as well with you, as though all men embraced the Gospel.”
(History of the Church, 1:468.)
