A questioning humble realist faith?

I was at a talk this evening called "Can you be LGBT and a person of faith". I went along because I'd heard one of the speakers before and wanted to hear people who had really thought about their faith talk. Sarah Jones (the person I had heard before) was excellent again and so were the other two speakers. One was a gay Rabbi and in his talk he focused on realising that the scriptures of his faith (and so to a certain extent mine) were built upon patriarchal structures. Another speaker was a lesbian quaker who talked about the Quaker idea of each persons search for truth needing to be respected. And in the questions section of the talk there two questions which really interested me one was "by questioning holy books are you undermining them". I loved Sarah Jones's response that it is "our holy duty to question, question and question our way to God". Another question asked if by questioning our texts do we not risk making God in our own image? Again Sarah's response was spot on we need to be humble about what we know and focus more on what we don't know and be careful that we don't make god "us with super powers".

Whilst none of this stuff is new to me, I've practically been raised with these ideas, I've recently discovered a certain tension. I spend my day in my course battling against the view that many viewpoints are all equally valid and that truth can be many things. I find anti-realist talk of this sort hollow, empty and unreasonable. Linguistic constructivism and other attempts to find another way of looking at truth just don't sit well with me in any sphere of philosophy. But yet in my faith I'm incredibly open... to being open. Maybe it's because I think that in God we really have the complete unknowable. But at the same time I've got my inner philosophical realist that keeps shouting at me but there's one truth. I know strictly there's no necessary tension in saying that there something we can't know and we should question and be humble about what we know with the idea of realism and that there's definitely a single truth out there. But I still feel this tension there and I'm not sure how to fully resolve it or deal with it. So many people of the "many different viewpoints" thing in religion also spout the anti-realism that so annoys me. At the same time those who seem to be solidly realist close are the ones that like claiming one source of divine knowledge. I don't think I'm philosophically opposed to my religious views (what on earth that would mean?) but I definitely keep poking myself to challenge my language to make sure that it's quite right and that I'm not letting myself slip.

I've got a lot more to say on this and I hope to re-visit it a few more times but I'm just going to sit and ponder this for now.
