If you are searching diligently for truth, and walk in front of a bus whilst doing so, God is not going to condemn you because you hadn't a perfect understanding of theology. Which brings me to ask a question... Does anybody have a perfect understanding of theology?
The thing is bro, we aren't saved or lost on the basis of sound or unsounded doctrine... We are saved by faith. But our faith must be in something real, tangible, and truthful. You will not be saved of your faith is in a block of wood.
So while you are searching, take care that you don't settle and think you've arrived. Your faith could turn out to be in a false concept or a false gospel. Stay open to the holy Spirit to lead you into more truth. And the moment you discover that you are wrong, change your mind...or that your pastor, priest, or Bible teacher is wrong, show him his error, and if he doesn't agree and cannot offer a biblical defense for his belief... Go somewhere else. And as enoch777 said, the Bible and the Bible only is the only reliable foundation for truth.
