Dunn puts it succinctly: "What pre-Christian Judaism said of Wisdom and Philo also of the Logos, Paul and the others say of Jesus. The role that Proverbs, ben Sira, etc. ascribe to Wisdom, these earliest Christians ascribe to Jesus." [James D. G. Dunn, Christology in the Making,167] This conception of Wisdom parallels a less significant, general Jewish explanation of how a transcendent God could participate in a temporal creation. The Aramaic Targums resolved this problem by equating God with His Word; thus, in the Targums, Exodus 19:17, rather than saying the people went out to meet God, it says that the people went out to meet the word of God, or Memra.

O'Neill [JCO.WD, 94] records the words of the Jewish historian Philo, a contemporary of Jesus, who laid out this exposition upon the three men who came to visit Abraham in Genesis 18:2, and were presumed to be divine figures: ”...the one in the middle is the Father of the Universe, who in the sacred scriptures is called by his proper name, I am that I am; and the beings on each side are those most ancient powers which are always close to the living God, one of which is called his creative power, and the other his royal power.”
No one would question that Philo was a Jewish monotheist; yet here we have an exposition perfectly compatible with the Trinity: the Father, The Creative Power (the Son, or the Word), and the Royal Power (the Holy Spirit).
