This work fills a gap in scholarship on one of the most controversial and significant textual variants in the whole Bible—the μονογενης θεος (unique God) of John 1:18. Renowned scholar F.J.A. Hort takes on this task with scholarly precision and erudition. He carefully examines the evidence for this important reading from the textual evidence of the Greek New Testament, Greek, Latin, and Ethiopic traditions, as well as the Nicene Creed. Hort then provides a valuable text-critical analysis of the fourth-century Eastern creeds.
