The word trinity defines God as being one God existing in three coequal, coeternal, consubstantial persons:God the Father, God the Son (Jesus Christ) and God the Holy Spirit — three distinct persons sharing one essence (from Wikipedia) . The trinity is not in the bible. Comparing Revelation 7:17 which says, because the Lamb that is in the midst of the throne shall feed them, and shall lead them unto living fountains of waters, and wipe away shall God every tear from their eyes. There is nothing in this verse that substantiate the trinity according to its definition.
In Revelation 4:8 and 11, creation is attributed to the Almighty God. Jesus never once called himself the Almighty God, Jesus attributed creation to God, not to himself Mark 13:19 For those days shall be tribulation, such as there hath not been the like from the beginning of the creation which God created until now, and never shall be.
The Lamb in Revelation 5:6 is Jesus who was slain and resurrected. In contrast, God is immortal. Jesus who called himself the faithful and true witness could not be considered truthful if he claimed to be the Creator but is actually not, making his statements in Mark 13:19 ASV, Matthew 19:4 and Mark 10:6 false. Mark 13 :19 says, For those days shall be tribulation, such as there hath not been the like from the beginning of the creation which God created until now, and never shall be". Matthew 19:4 ASV says, And he answered and said, Have ye not read, that he who made them from the beginning made them male and female. Mark 10:6 YLT says, but from the beginning of the creation, a male and a female God did make them.
The Lamb/Jesus has a God as Revelation 3;12 shows. Revelation 3:14 shows that Jesus was created. The same with John 3:16 Jesus was begotten. Revelation 3:14 says, And to the angel of the church in Laodicea write: These things saith the Amen, the faithful and true witness, the beginning of the creation of God. This verse again confirms that Jesus ascribes creation to God not himself. Jesus is dependent on the Father. In John 5:26-27 ASV For as the Father hath life in himself, even so gave he to the Son also to have life in himself and he gave him authority to execute judgment, because he is a son of man. Note that Jesus did not say he has "life in himself". The Father "granted" to the Son to have the same. According to Jesus nothing is essential to the Father. Unlike Jesus, the Father is not dependent on anyone to "grant" him the possesion of life within Himself. Jesus is begotten, The Father is not.
The trinity is not in view in this verse.
