Many people perceive the Book of Deuteronomy as “the second law,” following its etymology. It has been misunderstood because of the mistaken rendering of the Septuagint as “this second law” (see Original Text [OT] 1); should have been correctly translated as “a copy of this law,” however. This may also be precisely the reason of our indifferent feeling towards Deuteronomy as somewhat a “collection” of dry ordinances and testimonies that have little relation to the life of the spirit, justification by faith and perfection of freedom. This paper presents, in a qualitative manner, the inseparability and indissolubility of the theologico–historico–sociological dimension of Israel as a nation and as a believer – on how the faith-struggle of the people of Israel, during and after their entry into the Promised Land, is intertwined in their history and recollection of the past. Briefly, yet substantially, this paper will show the central theme of the Book – the call towards an interpersonal relationship between God and Israel. Situating Deuteronomy in its proper setting and actual form in history, defining the unique character of Israel as “God’s chosen people,” it also aims to magnify the impact of the message of Deuteronomy in contemporary times – that our faith (generically, “belief in the Divine”) cannot be divorced from our common life. Our perception of such a relationship should transcend “duty” and legalistic understanding.
