Seitz gives an introduction to reading what he refers to as “the Elder Testament” as Christian scripture—that is, as canonical literature (recognized, received, accepted, and applied by the Church) testifying to the Trinity, One God and Three Persons.
The writing is dense and flowery, though astute. The book reads like something of a summary of earlier research and writing by the author (see the footnotes and bibliography on this). But the chapters surveying the three parts of the Elder Testament (Pentateuch, Prophets, and Writings) are worth the price of the book and the time it takes to read it.
