cmdrjones, are you actually Christian or are you just claiming to speak for them? Because I am and I certainly don't agree with you on the "core tenants" of Christianity are, and neither do the vast majority of christians and christian leaders I've met. And I've been to a
lot of churches; all of the ones in my area and I go to a different one every time I go on holiday (admittedly mainly Anglican and Methodist ones in that case), so I would say I have a fairly good grasp of christian opinion.
I would certainly disagree highly with your interpretation of judas's comment to jesus, and the idea that the process of bringing the kingdom is not one of progress, but I don't want to turn this into an off-topic theological discussion.
However, what I will comment on is what counts as the "core tenants" of Christianity. Some would say that the "core tenants" are best summed up in the
nicene creed (for most Protestants at least the "holy catholic and apostolic church" means the world church, not the roman catholic one). I would disagree, I think it's too exclusive. I think a broadly better summary would be the ones we actually see in the bible:
Romans 10:8-12
But what does it say? “The word is near you; it is in your mouth and in your heart,” that is, the message concerning faith that we proclaim: If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. As Scripture says, “Anyone who believes in him will never be put to shame.” For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, for, “Everyone who calls on the name of the Lord will be saved.”
or
1 Corinthians 15:3-8
For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Cephas, and then to the Twelve. After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born.
And by that of course I mean loosely. There are bits even in these that are too exclusive if taken absolutely literally. For example I have heard a sermon which is explicitly based on a point of contention with the "last of all" bit.
