In a modern, liberal and secular society "crowd-think" may seem ridiculous, but I wonder what would have happened without "crowd-think," if people cared more about themselves than the rest of their group. I think their chances of survival would drop.
Don't forget that the New Testament Canon is just a "book." It is completely up to you how you want to read it. We have been contemplating the purpose of this book and its ideas for 2,000 years. We all have different views. The problem is that some people "require" you to see things a particular way.
Supposedly "good ideas" must be promoted and "bad ideas" must be demonised. I don't completely disagree with this philosophy. You seem to do plenty of that yourself.
Who wouldn't promote the good and demonise the bad? What disgusts me is when bad ideas are promoted as "good" and good ideas demonised.
It's all very subjective, which is why some people take drastic measures and try to achieve it by force. This is how "socially destructive" and controlling cults develop. The founder or leader thinks their ideas are so good and so important that they will actually try to force the issue and dominate over their followers.
Most of the time, people do not resort to such drastic measures. They do however, promote or demonise ideas depending on which ones they think should prevail in the end. You do it, I do it and plenty of others do it. Jesus certainly did it, so it seems to mandate that we should do it too.
The question is what would happen if we didn't do this. The human race would probably descend into total chaos and anarchy. That is what I think would happen.
Religious people promote ideas they find in a book. The difference between ideas that religious and non-religious people promote is therefore the book. Religions revolve around books and traditions. Religious people think these books are special or contain special ideas.
Different people reading the same book will develop different views on it.
However, because of the belief that a book contains special ideas, some religious people feel that a lack of consensus weakens the "specialness" of the book. I for one do not agree with this concept, but many Christians feel this way.
Most of what you regard as "Christianity" is this consensus I dislike. It isn't because ultimately I disagree with the idea of a consensus, but rather that I disagree with the current and contemporary established, dominant or mainstream views of Christians. Consensus is good when the consensus is right, but when it is wrong, the consensus is the problem. The NT does not prescribe or dictate Christianity. Christianity is not something to be dictated.
The consensus is external. Every human experiences a book differently so every reader will develop different views. There is no normative Christianity except that which is established and I disagree with the present establishment(s) whether it is the Catholic, Orthodox or Protestant churches.
We currently have what I regard as a heretical consensus and this consensus must be steered back to the correct consensus. Christianity needs reform and the two main questions regarding reform that I have in mind is (1) how to achieve reform and (2) what reforms?
I have my own views on this, as you do.
