"In the beginning existed the Word, and the Word existed with God, and the Word was a God." (The Coptic Gospel of John 1:1-14)
The Coptic language (unlike the Greek) used an indefinite article ("a" or "an" in English).
The Sahidic Coptic translation uses an indefinite article with the word 'god' in the final part of John 1:1 and when rendered into modern English, the translation reads: 'And the Word was a god.'
