Here is the original source for the seven deadly sins.
Pope St. Gregory the Great (540 - 604 A.D.)
Moralia in Job, Book 31, chapter 45
“The leader of the devil’s army is pride, whose progeny are the seven principal vices. While there are vices which attack us in an invisible warfare under the leadership of pride, some behave like officers and others like troops. For not all faults occupy the heart from the same quarter. But while the greater and less frequently occuring faults can overcome a mind not on its guard, the lesser but more numerous faults pour in en mass. And once pride, the queen of vices, has fully conquered a heart, she soon hands it over to the seven principal vices, or to her generals. The army follows these generals for there is no doubt the that persistent multitudes of vices follow them. We will better be able to demonstrate this if we ennumerate these leaders and the army. Certainly the root of all evils is pride, of which Scripture says, “Pride is the origin of all sin” ( Eccleciaticus or Sirach 10:15). The first of her progeny are certainly the seven principal vices which come forth from the virulent root, namely, vainglory, envy, anger, sloth, avarice, gluttony,lust. And because he is grieved at our being held captive by pride’s seven vices, our Redeemer wages a spiritual war of liberation for us, filled with a spirit of a sevenfold grace.”
