Hi LittleToe,
Of course each one of us need to settle this kind of issue on our own (without the help of biased parties). I settled this isue for myself a long time ago by honestly reading Pro-Trinitarian and Pro-Unitarian material and carefully examining those materials against the Bible. I found that the Pro-Trinitarian arguments always came up short.
To take the kind of reasoning (expressed earlier) a little further, one can observe that the word "Lord" is used throughout the NT to refer to both Jesus (Yeshua) and Jehovah (YHWH). Does that mean that both Jesus and Jehovah are the same? If so, why refer to them by different names? Also, why isn't the Holy Spirit also referred to as Lord or Mighty God? As for those who may say that there is no place in the NT where YHWH is found, many Bible scholars agree that there are places in NT text where the Tetragammaton should have been used.
Having said all of that, I've found that the issue of the Trinity has not been an obstacle to prevent me from enjoying fellowship with both Trinitarian-Christians and Unitarian-Chrisitans. None of us have everything 100% right and many of these issues will be clarified for us on the Lord's day.
