I wouldn't completely agree about evangelical churches and those who do Alpha being stuck in IBM mode, though I can very well see that a lot are, and the comparison does make me snigger a little. But I think we need to be careful with the word evangelical, actually. It is too often only used to mean fundamentalist, those stuck on literalism etc, when there is a whole branch which is totally not - open evangelicalism. Now I struggle with the word nowadays, because while I have generally self described as evangelical/open evangelical, I find there are more and more people who then put me in the Republican gun toting box, when I am as about as far removed as you could get (those who know me here know some of my political views
) - I wonder then if we need some new terminology which moves away from the word 'evangelical' but which still embraces the good things that open evangelicalism does.
For me, I take stuff out of many traditions, but evangelical charismatic is still where I am - in the true meanings of the words, rather than what they have sadly become.
As for Alpha, it generally reflects the church/group running it - I've done a few and none have been based around rules/regulations etc - they really do depend on the slant of the leaders, I suppose. I've done Emmaus too, and others - love that there is a breadth of material for different purposes and audiences.
Sorry, that's a bit tangential there from the OP and from Minnie - I have a bit of a high horse which I must get down from 
The computer analogy is interesting though. I think that we do change in our thinking and reasoning as society does, but for me there are central unchanging things about my faith which are constant. The stuff around it is husk, in a sense - and it's important for us to form views about this kind of thing, and views will differ, but the central stuff - the creed's outline - is always there, unchanging as God is unchanging. Something very peaceful in that somehow.
atthestroke yes, yikes indeed at the creationist magazines. Some of the stuff you have written about your sister makes me worry and sad, really. She told her kids Santa is satan? :( To me, this stuff doesn't make any kind of sense in the light of the faith I follow. But it's easy to say, I know. People do believe this and do hurt others when trying to enforce that belief. I wish things could be different.
