Is the idea of a "trinity" found in the Bible?

1 John 5:7
For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.

John 1:14
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.


Any questions?
