For me Christianity is about spirituality, union with the Divine, love, compassion, connectedness. It isn't about texts, or dogmas, or "thou shalt believe x's", though beliefs might come into it, they are merely the starting point for the experience that is the heart of it, and probably all spirituality (when practiced properly, at least in my opinion). I can understand that from an historical and literal point of view, early ("orthodox") Christians may not have held beliefs similar to my own, but I have no problem finding spirituality in the teachings of Jesus, and the experience of the Holy Spirit, just as they did. I believe the Divine speaks to us in different ways over the generations, but the essence, the humanity, the upliftingless of the experience is the same. And that it comes from the same source.
Science advances not by blind dogma, but by experimentation, buy questioning assumptions. To not treat spirituality in the same way is, in my eyes, to trivialize it. As Madeline L'Engle said "my religion is subject to change on a moment's notice. How dare I close myself off to God's revelations?" (sorry, don't remember her exact words, but that is it in a nutshell and I agree with it)
Just because a text speaks against something, or a Church (capital C) or institution, doesn't mean you can't be inspired by the same source and come to a very different conclusion...without invalidating the power of that source! (I think consistency and contradiction in religion is overstressed by a lot of people who claim to adhere to certain faiths...treating it too much as a dry, technical matter than the living experience it is.) So I don't have any problem admitting that historically (or even currently) most types of Christianity speak against "people like us" while still believing in God, after a fashion.
Mind you, my beliefs are very un-stereotypical, and many more conservative Christians would certainly not consider me one of them. That's totally fine. By their definition, I might not be. Words and labels aren't important to me, in general. But my spirituality comes from some of the same places they hold dear, and I feel it's very real and authentic (just as real as theirs, which I am by no means dismissing).
