The pdf document above is Myatt’s translation of and commentary on verses 1-14 of chapter one of the Gospel of John. As Myatt writes:
[Since] this translation is a work in progress, it will be updated as and when newly translated verses are available and is subject to revision. Extracts from the accompanying Commentary are given in the appendix. I have also included the Greek text (NA28) of vv.1-13 of chapter one so that those conversant with New Testament Greek can compare my translation of those verses to that text.
