Greed is an excessive desire to possess wealth or goods; Greed (Latin, avaritia), also known as avarice or covetousness, is, like lust and gluttony, a sin of excess. However, greed (as seen by the church) is applied to a very excessive or rapacious desire and pursuit of wealth, status, and power. Thomas Aquinas wrote that greed was "a sin against God, just as all mortal sins, in as much as man condemns things eternal for the sake of temporal things." In Dante's Purgatory, the penitents were bound and laid face down on the ground for having concentrated too much on earthly thoughts. "Avarice" is more of a blanket term that can describe many other examples of greedy behavior. These include disloyalty, deliberate betrayal, or treason, especially for personal gain, for example through bribery. Scavenging and hoarding of materials or objects, theft and robbery, especially by means of violence, trickery, or manipulation of are all actions that may be inspired by greed. Such misdeeds can include simony, where one profits from soliciting goods within the actual confines of a church. As a secular psychological concept, greed is an inordinate desire to acquire or possess more than one needs or deserves, especially with respect to material wealth.
