In addition to not addressing the Greek text whatsoever as Susan noted (rather than treating the Syriac as an early translation that provides supplemental evidence for an argument from the Greek text), I also downvoted for what I believe to be erroneous information (commonly espoused by Aramaic primacists) in your dating of the Peshitta (had you said 'by the fifth century' rather than 'before the fourth century', it would be accurate). — maj nem ɪz dæn ♦ yesterday
