There are hundreds if not thousands of books on the subject of the Trinity. I'm not here to argue Christian doctrine. I'm sure there are lots of places you can do so.<quoted text>
I don't know what you mean by the Trinity. If meaning Jesus was God incarnate there is nowhere in the Bible that points to God taking on human form in the body of Jesus.
Thorough study points out Jesus saying many times to not pray to Him but to the Father. One specific example is in Jesus speaking to the Jews;
John 5:37 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.
38 And ye have not his word abiding in you: for whom he hath sent, him ye believe not.
39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
40 And ye will not come to me, that ye might have life.
41 I receive not honour from men.
42 But I know you, that ye have not the love of God in you.
43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
If they had never seen God's shape nor heard His voice at any time how could Jesus be God while they were looking at Jesus and hearing Jesus' voice.
According to the text Jesus was not God and not simply a prophet. Beyond a prophet. Yet not God.
And while you never heard of anyone talking about Reagan being a Presbyterian or Nixon being a Quaker they sure did about Kennedy being a Catholic.
Jesus claimed to be God in the flesh (Jn 10:33), and again there are plenty of books going back thousands of years that cover this.
The conversation regarding Kennedy wasn't whether he was a Christian, it was how much influence the Church/Pope would have on his administration. Different supject than Romney.
