The Seven Deadly Sins are Pride, Envy, Anger, Avarice, Sloth, Gluttony, and Lust. Each of these sins has been written upon and rewritten upon over the last two millennia. Gregory's writings seem to have specialized in telling people how they should conduct their lives. He did this in two fashions: example and direct instruction. In Gregory's Pastoral Care, he provided priests with an ideal model of their duties with reference to their ministries. In Dialogues, he wrote of the lives of some of the saints of Italy, including Saint Benedict. Moralia in Job was a condensed list of vices or sins of which he wanted his parishioners to avoid.
Writers of the past have listed the Seven Deadly Sins in various orders of importance. Gregory however seems to equate all of them on an equal level. Equal meaning that they are all deadly and will cause damnation of the soul. They are called deadly because they are in opposition to love and damage to our personal relationship with God. Pope Gregory and Aurelius Augustine seem to have shared the same view regarding the role of love. God is love and he created us to love. Augustine's view of Disordered Love in many respects corresponds with some of the Seven Deadly Sins. The love of objects translates to avarice and gluttony. The love of people can lead to envy, anger, and lust. The love of oneself often results in pride. This makes perfect sense given that Saint Augustine and Pope Gregory lived during the same period. It is possible that Gregory's writings and teachings heavily influenced Augustine's views.
Who is it you have insulted and blasphemed? Against whom have you raised your voice and lifted your eyes in pride? Against the Holy One of Israel! (2 Kings 19:22)
So when the crowd had gathered, Pilate asked them, "Which one do you want me to release to you: Barabbas, or Jesus who is called Christ?" For he knew it was out of envy that they handed Jesus unto him (Matthew 27:17-18).
The first chapter of Romans lists envy along with other sins:
They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice (Romans 1:29).
Envy is the prelude and motivation for some of the worst crimes of man. The book of Acts tells how envy led to Joseph's brothers selling him into Egypt:
Because the patriarchs were jealous of Joseph, they sold him as a slave into Egypt (Acts 7:9).
Envy is obviously a very serious sin. However it is not so strong that it cannot be controlled. Peter taught to lay aside one's envy and to gain from the resulting spiritual growth.
Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation, now that you have tasted that the Lord is good (1 Peter 2:1-3).
1 Corinthians teaches how through love envy can be conquered:
Love is patient, love is kind. It does not envy, it does not boast, it is not proud (1 Corinthians 13:4).
Finally, Galatians teaches that envy will keep a person from enjoying the bliss of Heaven:
And envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God (Galatians 5:21).
But I tell you that anyone who is angry with his brother will be subject to judgment (Matthew 5:22).
Then he said to them, "Watch out! Be on your guard against all kinds of greed; a man's life does not consist in the abundance of his possessions." (Luke 12:15)
And put a knife to your throat if you are given to gluttony (Proverbs 23:2).
You will have these tassels to look at and so you will remember all the commands of the Lord, that you may obey them and not prostitute yourselves by going after the lusts of your own hearts and eyes (Numbers 15:39).
So, now that you know the sins, where do you stand with your creator?
