After establishing to his satisfaction the inevitability of a reader-oriented understanding of meaning, Martin then provides examples in which Christian interpretation of Scripture demands a reader-oriented approach.
In the first example, Martin points out that Christians read Psalm 22 in terms of the crucifixion of Jesus. Martin says that this is impossible based on a historical-critical approach. The Psalm was written by an Israelite many years before Christ (probably not by David according to most critics), and thus it cannot be interpreted by authorial intention in a Christian way.
Martin does note that many Christians have appealed to the divine authorship of Scripture, but he does not stop to consider the challenge this poses to his approach. By refusing to consider the possibility of prophecy of some sort and the role of the Divine Author, Martin fails to realize that the Bible actually demands its readers to be socialized into a particular way of reading Scripture.
By refusing to submit to the demands the Bible makes on its readers, Martin is bound to misread Scripture. This is most unfortunate, since by failing to read the Bible correctly, Martin fails to receive the meaning intended for him by the Divine Author.
