Cambridge Greek Testament Commentary
John 1 - Introduction
Ἰωάνην is preferred by the best recent editors to Ἰωάννην. The title of the Gospel is found in very different forms in ancient authorities, the earliest being the simplest; κατὰ Ἰωάννην or -άνην (אBD). εὐαγγ. κ. Ἰ. (ACLX); later MSS. have τὸ κ. Ἰ εὐαγγ.; and very many have τὸ κ. Ἰ. ἅγιον εὐαγγ. On Εὐαγγ. κατά see notes on S. Matthew, p. 80.
