I have been just reading and thinking about the whole relation between Sinai and Zion. Hartmut Gese’s chapter on The Law in his book Essays in Biblical Theology is extremely stimulating. Charles Scobie’s book on biblical theology has some interesting thoughts on this subject as well (The Ways of our God , pp. 517-550, 760-772). Gese makes the point that the Torah given at Sinai was given to one nation and there was an exclusive emphasis on it– a wall of separation was erected between the Holy and the Unholy. When the covenant was made and the atonement was made, representatives of Israel were allowed to ascend the mountain and eat and drink with God. The text clearly says that they saw God and were not harmed (24). They had unbroken fellowship with their Creator. Incidentally if you want to read an excellent book on Exodus 19-24 from a biblical theological perspective, I commend the Australian John Davies’. recent monograph, A Royal Priesthood: Literary and Intertextual Perspectives on an Image of Israel in Exodus 19:6 (JSOTSup, 395). It views this communion as a return to the Garden paradise in Eden. At any rate, to return to Gese, he sees the great banquet on Mount Zion at which all the nations have been gathered in Isaiah (25) as the eschatological projection of Sinai. But now there is a stress on inclusion rather than exclusion as holiness has permeated everything–it has knocked down all barriers. Thus death–the epitome of the unclean and unholy –has been eliminated forever. Here is the context for the inclusive Zion Torah, which seeks to embrace all (cf. Is. 2:1-5, 42:1-6). Gese develops the idea further in the NT on the Sermon on the Mount, where there is the fulfillment of this Zion Torah in the teaching of Jesus of Nazereth. But it is in Jesus’ life in particular, where this movement of holiness smashing down all barriers is effectively seen. He dares to touch the leper, he is touched by the contaminated woman, he touches the dead and raises them. His death brings about the radical cleansing for all on the day of atonement. And He sends his disciples into all the world, for he is its Lord. Great thoughts.
