The Overarching Law
“All things whatsoever ye would that men should do unto you, do ye even so unto them.”
The Derived General Principle
D&C 49:20 But it is not given that one man should possess that which is above another, wherefore the world lieth in sin.
The General Commandment
“Thou shalt love thy neighbor as thyself.”
The Specific Commandment
D&C 70:10, 14 And behold, none are exempt from this law who belong to the church of the living God … [I]n your temporal things you shall be equal, and this not grudgingly, otherwise the abundance of the manifestations of the Spirit shall be withheld.
The Specific Instructions To Carry It Out
“Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and thieves break through and steal, but lay up for yourselves treasure in heaven, where moth nor rust doth corrupt, neither do thieves break through and steal. But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal.”
Which is done like this: “Sell what you possess, and give the proceeds of the sale as alms to the poor, and you shall have treasure in heaven.”
“Give to every man that asketh thee, and of him who taketh thy goods ask them not again.”
“From him who would borrow of thee turn thou not away.”
“Lend [in context, even, or especially, to your enemies] hoping for nothing again [hoping you will not be paid back].”
The Observed Result
Among both the Christians in Acts, and the Nephites, “no man called anything his own.” The Nephites dwelt in peace until they apostatized - rejecting the commandments, starting up the economy again, and ultimately getting destroyed.
