Whether transgression is a special sin?

❌ Objection 1 : It would seem that transgression is not a special sin. For no species is included in the definition of its genus. Now transgression is included in the definition of sin; because Ambrose says (De Parad. viii) that sin is "a transgression of the Divine law." Therefore transgression is not a species of sin.

❌ Objection 2 : Further, no species is more comprehensive than its genus. But transgression is more comprehensive than sin, because sin is a "word, deed or desire against the law of God," according to Augustine (Contra Faust. xxii, 27), while transgression is also against nature, or custom. Therefore transgression is not a species of sin.

❌ Objection 3 : Further, no species contains all the parts into which its genus is divided. Now the sin of transgression extends to all the capital vices, as well as to sins of thought, word and deed. Therefore transgression is not a special sin.
