Daniel Boyarin is a professor of Jewish Studies at the University of California-Berkeley. Like Alan Segal before him, he is a Jewish scholar with a special interest in the two powers “heresy”. I’ve attached a PDF of his important Harvard Theological Reivew article, “The Gospel of the Memra: Jewish Binitarianism and the Prologue to John” (John 1:1-14). It’s a terrific piece of scholarship that demonstrates that John primarily got his doctrine of the Logos from the Old Testament and his own Jewish context, not pagan Greco-Roman thinking.
It’s scholarship like this that makes me (and others) groan when people like Bart Ehrman want to argue that the idea of Jesus being God was a late invention of the early church.
