Alma 1:23-25, 4:9-10 (thread)
"Now there was a strict law among the people of the church, that there should not any man, belonging to the church, arise and persecute those that did not belong to the church, and that there should be no persecution among themselves. 1/
"Nevertheless, there were many among them [members of the church] who began to be proud, and began to contend warmly with their adversaries, even unto blows; yea, they would smite one another with their fists... and it was the cause of much trial with the church.
