In this book the author contends that communal holiness is the central theme of the vine metaphor in John 15:1-17. Illumination of the Johannine vine metaphor is illustrated by drawing on background information on the vine and its metaphorical usage in the Ancient Near East, Old Testament, and Second Temple Period and to suggest understanding in light of the communal holiness of the covenant people of God. Comparing the themes of holiness and corporateness pertinent to the covenant the book also reflects the covenant with Israel in relation to John's understanding of the people of God. The notion of covenant, which embraces reference to the people of God as vine/vineyard in the Old Testament and Second Temple Period, underlies John's vine metaphor. The book focuses research on ANE viticulture to determine the context(s) of when the vine was used to refer to Israel in a covenant relationship with God. In this historical context the Johannine vine metaphor receive fresh meaning and relevance for the people of God.
