O God, deliver me by Your name; by Your power vindicate me. (54:3)
One of the quirks in my personal practice and teaching of Judaism is that I want our behavior to make sense. By this, I mean that the meaning behind what we do should be logical and should make sense in the real world. Certainly, much of religious tradition involves God and I have never been much interested in whether God’s existence can be philosophically or logically proven (or disproven). But I prefer not to engage in a Jewish ritual whose primary purpose is theurgic, an attempt to manipulate God. I find it non-meaningful, illogical, and offensive when we use God’s name or objects inscribed with God’s name for the purpose of ensuring our protection by or from God.
Case in point: the mezuzah. When I teach the mitzvah of mezuzah, I teach what I understand to be the Biblical intention behind writing certain of God’s words on your doorpost – to be reminded that the home ought to be a place in which God’s words are honored. The rabbinic explication of the mezuzah, that we write the mezuzah in the same way that one writes a Torah scroll (same parchment, same ink), reinforces the notion that one should be reminded that the home is a place of Torah.
A commonly offered explanation of mezuzah is that the letter shin and the word Shaddai (a name of God) stand for shomer d’latot Yisrael, guardian of the doors of Israel, and that the primary purpose of the mezuzah is literally to protect the occupants of the home from harm. To my mind, this is utterly nonsensical. It is theurgic and magical. It serves not to elevate religion and elevate the human soul, but rather to debase the name of God.
