Usury is a crime against God and man. Usury the charging of interest on debt is a crime against God because it frustrates and destroys the "plan of happiness" that God intends for his creation. Usury destroys the patriarchal order of the family. It compels and demands that mother's work. Usury destroys the family that God set up from the beginning as his means of populating this earth. It divides male and female and scatters their offspring.
Usury is a crime against man because it eats up his substance. Usury robs the man of the fruit of his labors leaving him empty. Usury demands that he not marry or have children. Usury keeps the man from fulfilling the measure of his creation and destroys his soul.
Those that practice Usury against God and against their fellow man are they who "do wickedly" and Usurers will be "as stubble" and "the day cometh that they must be burned." 1 Nephi 22:15
