We always hear that there are certain sins that cry out for vengeance from the Lord. These sins are particularly grievous because they offend or are directly contrary to our nature. Scripture lists these sins as those sins that immediate inflame the anger of God. The Catechism of the Catholic Church in paragraph 1867 states:
The catechetical tradition also recalls that there are “sins that cry to heaven”: the blood of Abel, the sin of the Sodomites, the cry of the people oppressed in Egypt, the cry of the foreigner, the widow, and the orphan, injustice to the wage earner.
They can be summarized as such:
- Willful murder
- Sins against nature
- Oppression of the poor
- Oppression of the alien, widow and the orphan
- Injustice to the wage earner or defrauding laborers of their just wages
