When studying the Trinity, it makes sense to start with the New Testament and the words of Jesus in passages like Matthew 28:19 and John 15:26. But what about the Old Testament? Was the idea of a Trinity or Godhead ever mentioned? Was it heretical, as it is in Judaism today?
These questions get more interesting when you consider Judaism’s monotheistic beliefs. “Hear, O Israel, the Lord our God, the Lord is one” (Deut. 6:4; JPS Tanakh) is the first line of the Shema, a prayer recited by Jews every day. This brings up another question. How could Jews in the early church believe Jesus was God if they grew up with monotheism—being taught there was only one God in heaven?
In this video segment, Hebrew Bible and Semitic language scholar Dr. Michael Heiser explains that before Jesus came, Jews did believe in the idea of a Godhead.
Dr. Heiser continues this lesson in the rest of his Mobile Ed course OT291 The Jewish Trinity: How the Old Testament Reveals the Christian Godhead. It’s the ideal course for those teaching or studying the doctrine of the Trinity and provides excellent content for conversations with Jewish friends.
