The tongue is a world of iniquity. [ Bible ]

Hypocritical piety is double iniquity. [ Proverb ]

He that sows iniquity shall reap sorrow. [ Proverb ]

They that plough iniquity and sow wickedness reap the same. [ Bible ]

Who is a God like unto Thee, that pardoneth iniquity, and passeth by transgression? [ Bible ]

Whatever mitigates the woes or increases the happiness of others is a just criterion of goodness; and whatever injures society at large, or any individual in it, is a criterion of iniquity. One should not quarrel with a dog without a reason sufficient to vindicate one through all the courts of morality. [ Goldsmith ]

In most old communities there is a commonsense even in sensuality. Vice itself gets gradually digested into a system, is amenable to certain laws of conventional propriety and honor, has for its object simply the gratification of its appetites, and frowns with quite a conservative air on all new inventions, all untried experiments in iniquity. [ Whipple ]
