JGG,
I've experienced some of what you're expressing here.
Ever since I became a Christian almost thirty years ago, I have, so to speak, often found myself only able to keep one foot within the typical American evangelical church, while I place my other foot within more philosophical and/or scientific ways of thinking.
I think the reason I struggle with fully settling into the typical evangelical church is that I often find many of my fellow Christians who adhere to their interpretations of Scripture without attempting to consider other various angles, or they are in fact prevented from doing so by overly enthusiastic, hyper-authoritarian ministers/pastors. I find that fellow Christians who attempt to limit my scope of inquiry and evaluation often give me cause to feel alienated (and not because I'm running from them, mind you, but because they flat out reject my alternative considerations or viewpoints, even though I'm confident that many of my interpretations are still within what can be called the "Pail of Orthodoxy.")
Sure, some of my experiences of alienation have likely come about simply because we live in a pluralistic nation where just about everyone, including Christian people, harbor differing viewpoints, viewpoints that are at times incompatible. However, I think the overarching, and unnecessary, problem is that many Christians too easily allow themselves to feel prohibited from 'exploring' Christian concepts, for fear that they'll somehow step into a 'heresy' and become separated from their church.
What I do to alleviate some of this possible tension is remain willing to listen to others, without freaking out, and allow them to speak their minds and share their viewpoints. AT the same time, I allow myself to explore many different viewpoints and/or interpretations of Scripture through philosophical investigation, not only studying alternatives I think I'll agree with most, but also those that I may disagree with. By approaching faith philosophically instead of literally and superficially (like many American Christians do), I allow myself space for stretching my mind and probing my questions. I also don't allow others to place unwarranted guilt trips on me, even when they may seem confident of their position.
In essence, I recommend to you to explore Christian faith, but don't allow hyper-conservatives (or ultra liberals) to spoil the search...
