22 And also they had peace in the seventy and eighth year, save it were a few contentions concerning the points of doctrine which had been laid down by the prophets.
23 And in the seventy and ninth year there began to be much strife. But it came to pass that Nephi and Lehi, and many of their brethren who knew concerning the true points of doctrine, having many revelations daily, therefore they did preach unto the people, insomuch that they did put an end to their strife in that same year. (Helaman 11:22-23)
There are several neat things in these verses. First, true doctrine preached puts an end to religious strife. We’ve seen elsewhere that it has more effect on the minds of the people than the sword or anything else. It dispels doubt and ignorance and can become a shield against deceptions of the devil. (Of course, when people are more determined to carry their point than to learn the truth, it is another story.)
Another neat thing is that Nephi and Lehi and many others who knew the true points of doctrine still had many revelations daily. Their strong foundational knowledge did not prevent them from learning more, and they were able to perform a great service with their knowledge by helping end strife over doctrine. I also suppose some of their revelations helped them settle the strife as well.
So a good question for us is, when there is religious controversy do we remember important applicable points of doctrine that can help us settle it? Can we think of verses of scripture on the topic? Can we find applicable scriptures? Are there words of the modern-day prophets on the matter? I suspect that if we haven’t consulted the scriptures or the prophets on the question then we haven’t yet done all we can do, whether we have questions or whether we’re trying to help someone else with questions.
