But brother, who determines what "Truth" is? If it was easy, there wouldn't be so many denominations. Believe me, I sympathize with you. But what I have decided for myself is this: I will try to find a local church that has a loving spirit and that I can mostly agree with. If we decide not to fellowship with any church that doesn't have 100% of the "Truth", we'll end up being a church of one, and I don't believe that's what Jesus intended.
On a personal note, just in the past few months, I have had a change of mind on something that was very important to me and which I was absolutely convinced that the Bible upheld. This has almost caused me to rethink my church affiliation options, but realistically I don't have much choice where I live.
Blessings to you.
