He isn't as far as I can tell. If anything, in the later years he was affirming his own signature kind of Christianity, which effectively psychologized the thing. Christ becomes a symbol for the human Self, really a state of the fully individuated mind that's overcome and integrated its own shadow. What he actually thought in terms of metaphysics is up for debate. I suppose if he believed in an actual God, but Christ as a symbol, then we could imagine his beliefs looked *something like a Judaism*, but I put him far and away from what we think of as *the Jew*. Peterson pretty much took after Jung lock step, so whatever you think about Jordan's views can't fall far from the tree.
