The word "trinity" is not mentioned in the Bible but the word "Godhead" is. Also, look at 1 John 5:7(NKJ):
Godhead means - a greatly admired or influential person.
For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one. I would suggest you do your research as even the trinity translators acknowledge that the Father, the word and Holy Spirit "DO NOT" belong in this verse. And while your at it, Check Matt 28:19 It says to be baptized in the Father, Son and Holy Ghost, this should "Not" be there either. There are quite a number of verses stating, baptism is to be in the name of Jesus.
