St. Ambrose turns against the Novatians themselves another objection concerning blasphemy against the Holy Spirit, showing that it consists in an erroneous belief, proving this by St. Peter's words against Simon Magus, and other passages, exhorting the Novatians to return to the Church, affirming that such is our Lord's mercy that even Judas would have found forgiveness had he repented. · Sacred Texts
