The Vatican needs some usability testing for their website. People won't read those long pages.

Haha yeah it was way to long to read but I'm curious now.

Social injustice, that List was not actually a list, it was part of something the Pope wrote months ago, it merely made the news this week since one of the ArchBishops referred to it, after he was discussing in an intervew the problems with the lack of people going to confession.

Also it was not a "replacement" as the news tries to make if of the Churches teachings on mortal sins ( which was where the teachings of deadly sins came from( those are the sins that can according to church teaches separate you from God by committing them.

These "sins" came about as of a paper written on the social injustices in society and the churches responsilbity.
I tried to find the exact part where these new reponsilbilities of the church were addressed,

It is just that when the Pope actually made the address there was not even a mention of itin the news, a Bishop makes reference months latter and it makes some headlines, normally with one news sourse using the other as a reference.

But the link explains the churches teachings and belief as to the need for addressing these as sin.

One thing to note, just because everyone pollutes in some way, does not make it not a sin.
Everyone murders in there heart (e.g you think or say "i wanna kill him" but you don't really mean it but it still counts) everyone looks upon others with lust in their hearts, etc.
Who originally decreed what the 7 deadly sins are? If this information came from god, then the pope has no right to adjust it, especially in a way which removes important sins from the list, but maybe it was an earlier pope or figure in the catholic church which came up with them in the first place. Anyway, I think the point of the seven deadly sins, in my view, is to outline the primary, undiluted sins, which are the roots from which all other sins come, genetic engineering and pollution are too specific, especially since they have there roots (if genetic engineering is even a sin) in the seven deadly sins (eg greed and sloth could cause a company to not bother paying the money to clean up its pollution)

My opinion on genetic engineering is not yet fully formed, as we do not know much about it. I think it needs to be properly regulated, and that very stricltly, mostly theoretical research should be done to help determine guidelines and rules and the inherent dangers, and whether man is ready to change the genetic code, because it may be a thousand years before mankind is truly responsible enough for such awesome power.
