Mark 3:30

ὅτι ἔλεγον. It was because they gave such a wicked interpretation of His beneficent acts that He uttered His solemn warning. They had blasphemed the Son of Man, and were in danger of becoming blasphemers of the Holy Spirit, for their theory made any proof of Christ’s Divine Sonship and mission impossible. To accept it was to become incurable. This verse is the Evangelist’s own explanation of Christ’s stern utterance; it is no part of His utterance. Cf. Mark 7:19, καθαρίζων πάντα τὰ βρώματα. Mk says πνεῦμα� instead of Βεελζεβούλ in antithesis to τὸ πνεῦμα τὸ ἅγιον. The explanation is not in Mt. or Lk.
