John 1:1 as Prooftext provides a careful analysis to answer the question of whether this verse supports the doctrine of the trinity. Garrett C. Kenney examines the subtleties of many interpretive problems, balancing arguments on both sides of the debate in order to provide a sound foundation for further investigation and dialogue. He thoroughly explains and applies methods of textual, lexical, grammatical, and translation criticism to the interpretation of John 1:1. He also explains and partially applies methods of source, form, redaction, rhetorical, and composition criticism while acknowledging the need for further dialogue regarding the implications of this verse for those from both the Trinitarian and Unitarian viewpoints. Kenney's conclusion favors a Trinitarian interpretation, yet admits that the Unitarian position poses serious questions.
