Good points.The whole conclusion of this matter is What someone else thinks is a Christian and what the person who believes themselves to be a Christian is not open to anyones opinion except it is between the "Christian" and God.
If I say I'm a Christian, end of story I don't have to justify my beliefs to anyone it is a personal relationship and If God is happy, and I'm happy then everything is great.
It doesn't have to rely on the beliefs that have evolved over thousands of years. What is important is what was originally believed by the character Jesus in all documents we have on the myth. We know things were lost we know things were burned but whatever. If anyone goes by writings of Jesus they are going by someones opinion of Jesus like if the writings are from Paul or whoever. What the opinions of the original writers of Jesus were is debateable but it is what we have on the character and people draw their own conclusions on who Jesus is supposed to be. Everybody throws the lukewarm verse at each other and nobody agrees on what it symbolises. Jesus is supposed to hate the non-real christians and it sounds like we wouldn't even know it.I believe that words have meaning-- you don't just get to make up definitions in order to be all-inclusive. The core beliefs of Christianity have been largely defined by the past 2000 years of existence. These beliefs are what is important in determing the definition, not merely the fact that Jane Doe decides to call herself a Christian.
I think my definition of Christianity is about as general and inclusive as you can get, while still making a meaningful distinction.
What of atheist Christians? Or the example I gave back on page 1?
Besides, you don't really define Chrisitianity by saying it's simply the "religion for all the people who call themselves Christians." That just begs the question: What is a Christian?
To be clear, it's more of the intellectual concept of what constitutes Christianity that interests me, not the ability to go around saying "You're not a real Christian, so ha!".
