Non-muslim terriorist kills 84 in Norway.

[Judas BentHer]

First of all you obviously do not understand what Christian denominationalism means, none of them claim to be the only “true” faith, they just disagree on doctrinal issues or church government issues but they all agree on Christian dogma.

I've thought this for a great many of your posts now and this last one that I will indulge, confirms it. You're a Troll. Not a Christian. In fact, I'd go so far as to posit you are quite possibly an atheist, perhaps an atheist who is a member here and this is your sock account. Only the IP, if that, will show for sure. You know not even the basics of Christianity. You berate people who know more than you, like myself, thinking we'll take umbrage and retort to your disgraceful level and ignore the fact you know hardly anything about the faith you claim to defend here.

I wasn't going to do this. Howevever, it's not to educate you because you have no interest in learning what you so obviously, and with great regularity in this thread alone, demonstrate you know nothing about. Rather, this is offered to demonstrate that you, a Troll, are so inclined to flame baiting that you never think how easily your false empty claims can be proven as such.

Denominationalism

1. adherence to particular principles, esp to the tenets of a religious denomination; sectarianism
2. the tendency to divide or cause to divide into sects or denominations
3. division into denominations

Secondly, the 7 deadly sins never appear in the Bible.

Never? Never, ever? Oh, you must mean there's not a scripture that denotes a point by point list. No, that can not be your intention. My mistake. Because you said the 7 deadly sins never appear in the Bible. Or maybe you think that because there's not that list preceeded by something to the effect; "These are the 7 deadly sins ..."
Do you remember how many Theists here talk about context? And the alternative definition of a word, as opposed to that which may be said to take a verse proffered in a post out of context? "Deadly" is to be understood as transgressions that are fatal to spiritual progress. (The Seven Deadly Sins)
Now while there are some real Christians who will claim these sins don't truly threaten them because of Jesus sacrifice, that no sin is truly "deadly" to the Christian, i.e. any transgression that can be fatal to spiritual progress, the "word" says differently. Because after all, what is "sin"?

Romans 3:9-12 (KJV)

What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin; As it is written, There is none righteous, no, not one:There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.

Unless of course a Christian , a real one, chooses not to accept that and then there's a solution to the problem. A verse that affords something they can live with, in denial at will, as a "Biblical Christian".
1 John 3:9
King James Version (KJV)
Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.

Oh, drats! There's that pesky errancy issue again.

Matthew 12:31-32
Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.

Lastly, given your worldview, why would all of those things (racism etc) be morally wrong? Please be specific because I am interested to hear how you determine wrong from right.

No you're not. As to the first part of your question, I can understand how you would need someone to do the legwork so as to provide your ignorance an answer even to that. However, that you would even ask how racism, bigotry, homophobia, etc... would be morally wrong allows one to infer you do not consider them to be so... Oh hell, you are a Biblical Chrisitan!
