No connection between Christianity, and what being a Christian means. None, whatsoever.
What is your point, that unless a religious adherent meets your standards they are not actually members of their purported religion?
Or that the US is not a religious country?
Or that the US is not a Christian country?
Or all of the above?
Countries are not a religion. A country is a political region. Only an individual can be religious.
And I would even argue that all people are religious. All of them are. Atheists are religious.
It's always fascinated to see so-called Atheists, when something terrible happens like 9/11 or Katrina, ask "How could G-d let that happen?" If there is no 'god' then why are you asking why bad things happen?
Atheists are highly devoted to a fundamental belief system. It's just a belief system of themselves. Which if you read the Bible, was the belief system of Lucifer. You can make the implication there.
So back to your original question, the answer is 'none of the above'.
None of your suggestions, is what I implied but you came close.
You see this? This is a membership card to the Toronto Vegetarian Association. (as you can read).
There are numerous vegan groups and societies that have membership cards, and many offer 10% discounts at vegan shops in their area. Granted I don't live in Toronto, but say I did and I sent in my membership, and paid my dues, and got my Vegan Membership card. I'm a vegan.
Of course, I just (a minute before writing this) wolfed down chicken curry with spicy sauce. But I'm a Vegan. I pay the Vegan society. I have a Vegan card. I'm a Vegan!
Am I really a vegan? No. What?? Are you suggesting that no one can be a Vegan unless they meet YOUR standards of what a Vegan is?
No, that would not be your suggestion would it. You would suggest that a vegan by definition of what Vegan means, implies that you don't eat meat, and I just had chicken, and yesterday a burger. Thus I am not a Vegan by the definition of the belief system itself... not your personal views.
Similarly... it's not "my standards" of what a Christian is. It is the standard that the Bible itself makes, which is the only thing Christian faith is based on. If you remove the Bible, then there is no Christianity.
The Bible defines what a Christian is. And if you don't follow what the Bible says, then you are not a Christian. Even Jesus..... CHRIST... said this.
Matthew 7:21
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. Many will say to me on that day, 'Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?' But I will reply, 'I never knew you. Get away from me, you who break God's laws.'
In this passage, Jesus himself makes it extremely clear... you are not who you claim to be. I can call myself a Vegan until the end of time, and have all the Vegan membership cards that exist in the world.
None of that matters. I am not a vegan, if I don't follow the rules of being a vegan.
Jesus said, you are not a Christian because you preach in Christs name. You are not a Christian because you supposedly perform miracles.
You are a Christian if you follow the laws of the Bible.
And the fact is, very very few of the "christian" people in America, still follow the rules of the Bible. If they are shacking up, or sleeping with their boy friend / girl friend... then they are not following the Bible. That alone wipes out the vast vast majority of "western christians".
