Pagan philosophy got included in the Trinity doctrines. It was at a time when the Holy Spirit was pretty much unknown among the leading theologians. It was at a time when doctrine was controlled by the pagan Roman Empire. If people would turn to the human Jesus Christ, alive from the dead, then hold to his teachings and those brought by the Holy Spirit, they would find the one true God, the Father and He might say to them as He did to me, “I am God” and show then that the human Jesus is His true Son, beloved by Him. And He would give to them the Holy Spirit to seal the whole matter.
