 Mendelssohn adds a further reason for insisting that Judaism is a religion of the spoken word, precisely as a supernatural legislation rather than a revealed religion. The constant attention paid to the written word not only can isolate human beings from one another and speculation from practice, but also can induce a kind of idolatry. Frozen in time, the written word can become an idol itself, obscuring the distinction between itself and what it is meant to signify (see Freudenthal (2012), pp. 105–134).
