“... GTh 25 has a version of the “love your neighbour as yourself” saying with the variation ‘as your soul’, and a further amplification: ‘guard him like the pupil of your eye’. This second half in particular does not correspond closely to anything in the Synoptic tradition. There is, however, a section of the Epistle of Barnabas which has a close parallel – not to my knowledge previously noted – to both halves of the Thomas saying here (see Table 12.1). The parallel is not exact, nor are the two statements adjacent in Barnabas’s version. Nevertheless, there are remarkable similarities: as was discussed in Chapter 3, the love commandment in both cases makes use not of the simple reflexive (ὡς σεαυτόν), but – as is much less common – of a reference to the soul (ὑπὲρ τὴν ψυχήν σου, and [...]). Even more unusual is a nearby reference in both cases to loving or guarding ‘like the pupil of your eye’ (ὡς κόρην τοῦ ὀφθαλμοῦ, and [...]). [...] Two points are evident here. First, GTh 25.1 is closest to Barnabas, which also casts its version of the “love thy neighbour” saying as a generally applicable aphorism. Second, Thomas is also in some agreement – against the Didache – with Barnabas in appending a reference to loving or guarding ‘like the pupil of your eye’ – a strikingly distinctive phrase. ...”
