A simple reasoning
According to non trinitarians Jesus came after the Father. So Father is the first being and Jesus is the second being in this universe.
Father claims “I am the first, and I am the last;” and Jesus also claims “I am Alpha and Omega, the beginning and the end, the first and the last.”
Is it not a lie; When Jesus being the second person in this universe and first being God the Father how can He claim that He is first like God the Father.
Also God the Father claims “beside me there is no God.”; Bible says that Jesus is God.
Where is the error here. Is it with Trinity or non trinity?
