Interesting spin but you have a cause and effect issue here.  
The self-righteous mindset and exclusionary actions of the Pharisees was what Jesus critiqued not their beliefs.
Sure, they didn't believe him but that was because it was against their self-interest to do so.
Regardless, their actions pre-ceded the incarnation..
		
		
	 
The self-righteous mindset was directly related to their beliefs, unless of course interpreting the Law of Moses wrong is an action and not a belief. [/sarcasm]
We see Jesus not only setting their actions right, but their beliefs as well (for instance when he said that what goes into a man does not make him unclean, an idea repeated in Paul). There is not so large a dichotomy between actions and beliefs.
	
	
		
		
			Who was excluded from Jesus' table?
Who did Jesus say our neighbors happen to be?
		
		
	 
The neighbor is the man who does the right thing, not the man who believes the right thing and yet does the wrong thing. So?
	
	
		
		
			Sure.  
But why do you think that is?
Why do you think dogmatic theological statements or beliefs were not among the more important aspects of Jesus' teachings?
		
		
	 
It doesn't matter. Even if we don't find Jesus laying out systematically what Christians have to believe, he didn't say many other things that were relevant and that the early Christians would have to work out for themselves. The best argument you have here is an argument from silence.
	
	
		
		
			Well sure but they believed, as do I, that those statements were true.
They did not, however, say that you cannot follow him if you disagree about certain theological statements.
		
		
	 
Of course they did. Paul talked about "removing the evil brother from among you" for a certain period of time when necessary, and he accepted as an Apostle by the others. He also said that without the resurrection our faith is vain and we are dead in our sins.
Still, I'm afraid you're thinking in black and white (which is ironic since conservatives are often accused of doing that). It's possible for a non-Christian to be more righteous than a Christian without the conclusion being "it doesn't matter what you believe." The conclusion would be "the non-Christian is actually acting more like a Christian than the Christian is!" 
	
	
		
		
			In fact, Paul had something to say about following Jesus and worshipping God even if that fact is "Unknown" to those who do so....
		
		
	 
He appealed to them on common ground in order to introduce them to Jesus, not to leave them to their beliefs and go on his merry way. Some of the people who heard him talk about the resurrection wanted to hear more, others sneered and Paul left (Acts 17:32). I guess you didn't read far enough.
	
	
Gee, the deity and resurrection of Christ is central for Protestants, Catholics, and Orthodox (or at least among the non-liberals therein) and of course for the Bible and the early Church.
	
	
		
		
			What is central to a Catholic is different from what is central to a Protestant fundamentalist as well as different from what is essential to an EO.
		
		
	 
And we should be ashamed that these points of division exist, but we should not gloss them over.
	
	
		
		
			Most EOs consider all Western Christians heretics because a simple sub-sentence that states "and the son" was added to a certain creed many years ago...
		
		
	 
Well I'm glad you could tell me what I believe. Clears up a lot about the way you think.
