Godhead v the Trinity

As I have stated before one of the biggest differences between the Catholics and Mormons is the Trinity. Both concepts make sense and do not make sense. There are so many references in the scriptures that the Father, Son and Holy Spirit (Ghost) or different entities. I have decided to try to bring some form of logic into this question for me. (I know~religion and logic are really not a good couple to mix). I went looking into the Bible, John 14:15 came to my attention. If ye love me, keep my com. Unlike many scriptures, that are quotes to me in opposition to the idea of the Trinity, I do not see how this can be taken any other way.
