To my knowledge there is no universally accepted earthly arbiter on who is and who is not a true Christian.
Let’s put it this way.
Suppose I claim to be a die hard vegan but eat beef, chicken and fish 5 times a week. Wouldn’t anyone with half a brain see straight away that I am far from being what I claim to be?
Spong thinks he is a Christian because he is trying to follow Christ as best he understands what that path is.
And I suppose I could call myself an American if I try to believe I am an American and advocate that everyone sing the Star Spangled Banner every morning?
You think he is not because you think he is wrong about what that path is.
I know he is not because he has already said so. He has enunciated beliefs that are contrary to the bedrock of Christianity - that God is a Trinity and that Jesus is God. What Spong advocates for is more deism rather than theism.
Christ did not come to give us a set of ethical rules. Even before He came, those ethical rules were already in place and some are already following them. Christianity is about God who became Incarnate. Jesus is not just another guru in a long line of a “supposedly” enlightened gurus. To be Chrisitan is to believe that Jesus is God.
Who should I believe is right, and why should I believe it?
How about you work that out for yourself based on what has been written here? But do rumiinate on them for a while.
Why not admit that all living humans could be wrong about the best way to be a Christian?
See this is where you are wrong. That is only possible if like Hinduism, Buddhism and any other isms there is no revelation from God. But we have Christ as the revelation of the Father. So there is no second guessing here. We know the way to being a Christian because Christ Himself has shown us the way. We do not follow a set of ethical teachings, we follow Christ. The Good News, the Gospel, is Jesus Christ Himself.
Isn’t enough that the man has devoted not only his career but his whole life to trying to discern what it means to be a follower of Christ?
No it isn’t enough. A good dose of humility is required as well.
That qualifies him as a Christian in my book.
Well your book does not matter becausse by your own admission you are no a Christian yourself but a none. And this is in no way meant to belittle you. Just a statement of fact.
I can’t imagine a more relevant criterion than that.
You can’t. But I can. And based on what I have written above, I think I am slightly better qualified to asses this matter than you are.
How would you feel about some Christian non-Catholic saying that Catholics aren’t REAL Christians because they have certain doctrines wrong? I guess this is no hypothetical.
Now the so called Bible believing Christian are quite right to do that because after all they really do believe in Jesus Christ as God. But their assessment is wrong because they do not know what we actually believe. As a matter of fact, protestants who took the time to really study the Bible and history realized that Catholic Church is the true Church of Christ.
But I must say I have a lot of admiration for the protestants who truly love our Lord and acknowledge Him as True God.
