Sin ... what a concept! It presupposes something or someone that could be sinned against, when most of what passes for "sin" is merely an act of selfishness, or a neuropathic behavioral disorder.
Pride: Obsessive, compulsive, and/or excessive desire to be more important or attractive than others, and excessive love of self - especially the willing refusal to submit to a subordinate position toward God and religious authority. People that willingly exercise their freedom to choose are often considered Pride-filled, especially when they choose to not submit to church authority and display the annoying tendency to withhold money for tithes and offerings from the church, which takes its percentage before passing the remainder (if any) along to the poor.
Lust: Obsessive, compulsive, and/or excessive desire or thoughts of a sexual nature. The Christian religions object to Lust mainly for its inherent distraction from devotion to God and other religious practices, such as attending indoctrination sessions (a.k.a.; Mass, Bible study, Sunday School, et cetera.), tithing, or makings monetary offerings to the church.
Gluttony: Over-indulgence and over-consumption of anything to the point of waste. The Christian religions object to Gluttony because of the excessive desire for food, and/or the willing refusal to share it with the needy. Money spent on consumables is not tithed or offered to the church.
Greed: Desire for the acquisition of extreme wealth, status, power, or influence. The Christian religions object to Greed because of the excessive desire for material wealth, and/or the willing refusal to tithe or offer money to the church.
Sloth: First called the Sin of Sadness or Despair. Early Christian writers described Sloth with the same or similar terms used to describe Clinical Depression - apathy, depression, joylessness, and melancholy. The Christian religions object to Sloth because slothful people don’t work, those who don’t work don’t earn money, and those with no money have nothing to tithe or offer money to the church.
Wrath: Obsessive, compulsive, and/or excessive desire or thoughts of a violent nature, such as revenge, murder, hatred and anger. These feelings can manifest as willing denial of Biblical “Truth,” and the willing refusal to tithe or offer money to the church.
Envy: Obsessive, compulsive, and/or excessive desire for something that another person has that is perceived as lacking in the envious person, and the willful desire that the other person to be deprived of – such as monetary tithes and offerings to the church.
NOTE: All of these so-called "Sins" have at their root the exercise of free will, which any religious or secular authority abhors for the tendency of people to choose to administer their own self-interests, rather than become mindless drones under the control of a religious or secular authority.
Once you convince a person of their sin-filled nature, you can use their own guilt and shame to manipulate them to your ... uh ... God's will, especially when it comes to indulging them to buy their way out of eternal damnation with their tithes and offerings to you ... uh ... the church.
