We cannot give an adequate account of the different kinds of sin, unless we can also describe different kinds of virtue. So, let us remember, there are three kinds of virtues and correspondingly three different kinds of vices or sins. They are as follows:
- Virtues and vices which pertain to the heart. These indeed are the real virtues or vices.
- Virtues and vices of the tongue or expression.
- Virtues and vices which entail the use of the other physical organs like hands, feet, eyes, etc., etc.
