"The proud are easily offended and hold grudges"

From Ezra Taft Benson, “Beware of Pride” Apr, 1989

Another face of pride is contention. Arguments, fights, unrighteous dominion, generation gaps, divorces, spouse abuse, riots, and disturbances all fall into this category of pride. 

Contention in our families drives the Spirit of the Lord away. It also drives many of our family members away. Contention ranges from a hostile spoken word to worldwide conflicts. The scriptures tell us that “only by pride cometh contention.” (Prov. 13:10; see also Prov. 28:25.) 

The scriptures testify that the proud are easily offended and hold grudges. (See 1 Ne. 16:1–3.) They withhold forgiveness to keep another in their debt and to justify their injured feelings.
…
Pride is the universal sin, the great vice. Yes, pride is the universal sin, the great vice.

I am amazed at how universally applicable this principle is.  Pride, as defined in the scriptures, is the root of all sin.
