One trouble with the Trinity is the word 'Trinity'. It conjours up the association of paganism because of the word 'trinity'.
Trinity [the actual word] is not in the bible anywhere. fact.
The Trinity was not explicitly understood/explained until after the scriptures were written. fact.
Scripture indicates that there is a Trinity of beings who have the glory and power of God? fact. Some scriptural examples follow.
God raised Jesus from the dead, right? [gal1;1 says the Father raised Jesus, Romans 8;11 says the Holy Ghost raised Jesus, John 10;17-18 says that Jesus raised himself]
God dwells in believers [1cor 3;16-17] say the Father dwells in believers, [Romans 8;9] says that the Holy Ghost dwells in believers, [John 14;18] says that Jesus dwells in believers.
The Father searches the hearts and minds [Jer 17;10], The Holy Ghost searches the hearts and minds [1cor 2;10], Jesus searches the hearts and minds [Rev 2;23]
The Father gives us the words to speak [Math 10;19-20] Jesus gives us the words to speak [Luke 21;14-15] The Hoy Ghost gives us the words to speak [John 14;26]
Jesus commanded to be baptised in the name of the Father, the Son and the Holy Ghost [one name, 3 beings]
The only way to absorb the fullness of all scripture, without contridiction, is to acknowledge that there is more to God than we can understand and furthermore, this 'progressive revelation' of the nature of God will continue as it has since humanilty had first cried to God.
Just mho.
