Mosiah 18:21 - 18:25

Mosiah 18:21 And he commanded them that there should be no contention one with another, but that they should look forward with one eye, having one faith and one baptism, having their hearts knit together in unity and in love one towards another.

The goal of the community was to eliminate contention of any kind amongst themselves. They were to be united in doctrine and concern for one another.
[This is not a place where selfish people are only looking out for themselves. What happens to me happens to all. When I greave we all greave. When I am happy we are all are happy.]

Mosiah 18:22 And thus he commanded them to preach. And thus they became the children of God.

This was Alma’s instruction to his priest as to how they were to lead the 50 people they were responsible for. This is how God rules his people from heaven and how we are to lead on earth.

Mosiah 18:23 And he commanded them that they should observe the sabbath day, and keep it holy, and also every day they should give thanks to the Lord their God.

He commanded that they should live the Sabbath day as it says in the law of Moses. That they should pray everyday thanking God for that they receive from Him.
[We just don’t see things come into our hands without thinking about where they came from whether we earned them by our labor or given to us as gifts.]

Mosiah 18:24 And he also commanded them that the priests whom he had ordained should labor with their own hands for their support.

Alma also said the priest were to support themselves with their own labor. The people were not to pay them a salary for their work as priest. Being a priest was a avocation not a vocation.

Mosiah 18:25 And there was one day in every week that was set apart that they should gather themselves together to teach the people, and to worship the Lord their God, and also, as often as it was in their power, to assemble themselves together.

They got together one day a week for a worship service. They were to have classes in doctrine and instruction. They were to assemble together oftener if possible.
