Christological interpretation

For the writer to the Hebrews, Christological interpretation is an absolute necessity. Earlier revelation was fragmentary – many parts, many ways – but His new speech is unified in huio – in the (one) Son. Without Jesus, the interpretation of the Hebrew Bible lacks unity.

Would the writer to the Hebrews be surprised that the modern assault on typology had produced a source criticism that in turn produces a seemingly boundless fragmentation?
