Luke 5:8

Πέτρος : here for first time introduced without explanation, presumably in connection with the great crisis in his history. ἀνὴρ ἁμαρτωλός : a natural exclamation especially for an impulsive nature in the circumstances. But the utterance, though real, might have been passed over in the tradition. Why so carefully recorded by Lk.? Perhaps because it was a fitting thing for any man to say on becoming a disciple of the Holy Jesus the sin of the disciple a foil to the holiness of the Master. Also to supply a justification for the statement in Luke 5:32, “I came not to call,” etc. In this connection sin is ascribed to all the apostles when called, in very exaggerated terms in Ep. Barnab., Luke 5:9 (ὄντας ὑπὲρ πᾶσαν ἁμαρτίαν ἀνομωτέρους).
