But these several sins have each their army against us.
For from vainglory there arise
- discords, and
- the presumptions of novelties.
From envy there spring:
- exultation at the misfortunes of a neighbour,
- and affliction at his prosperity.
From anger are produced:
- swelling of mind,
From melancholy there arise:
- slothfulness in fulfilling the commands,
- and a wandering of the mind on unlawful objects.
From avarice there spring:
- violence, and
- hardnesses of heart against compassion.
From gluttony are propagated:
- foolish mirth,
- dulness of sense in understanding.
From lust are generated:
- blindness of mind,
- hatred of God,
- affection for this present world,
- and dread or despair of that which is to come.
Because, therefore, seven principal vices produce from themselves so great a multitude of vices, when they reach the heart, they bring, as it were, the bands of an army after them.
— St. Gregory the Great, Moralia in Job, Book XXXI
