Using the words of Selwyn Duke from his article:
Why many American Christians really are un-Christian
"Heck, if I thought religion was just a fancy name for opinion, I'd become a hedonist — or at least a Unitarian."
Duke continues with:
"Let us be blunt: It is simply not possible to espouse relativism — which holds that right and wrong are opinion — and be a true Christian.
Why? It's simple: Jesus did not die for our opinions. Jesus did not say that His blood was the blood of the new and everlasting covenant and that it would be shed for you and for all so that opinions may be forgiven; He did not say, I am a way, a truth, and a life; He did not say, let he who is without opinion cast the first stone; He did not say to that dark tempter, "It is said, 'Thou shalt not tempt the Lord thy God,'" but, hey, Satan, whatever works for you.
There are many doctrinal differences among the denominations, and good people could debate them ad nauseam and still not settle every one. Yet, if anything is central to Christianity, it's the belief that Truth is spelled with a capital "T," that it is absolute, universal and eternal. And also central is a corollary of this belief: that there is an absolute, universal and eternal answer to every moral question; that right and wrong are not a matter of opinion, that they don't change from time to time and place to place."
Other than you not being an American, can you relate to the article?
