St. Pacian on Baptism

St. Pacian of Barcelona ca. 310-391

Freed therefore from our bonds,  when through the Sacrament of Baptism we come unto the Sign of the Lord, we renounce the Devil and all his angels, whom before we served, that we should now serve them no longer, being delivered by the Blood and Name of Christ. But if after this any one forgetful of himself and ignorant of his redemption, return again to the serving of Angels, and to the weak and beggarly elements of the world; he shall be bound again by his old fetters and chains, that is, by the bonds of sin, and his last state shall be worse than his first. For the Devil shall bind him more strongly, as if overtaken in flight, and Christ shall not now be able to suffer for him; for, Christ being raised from the dead dieth no more. Therefore, dearly beloved, we are washed once, once are set free, are once admitted into the kingdom of heaven; once is that, blessed is he whose unrighteousness is forgiven, and whose sin is covered. Hold mightily what ye have received; keep it. blessedly, sin no more. Preserve yourselves pure and unspotted from that time even to the Day of the Lord. Great and boundless are the rewards granted unto the faithful, which eye hath not seen, nor ear heard, neither have they entered into the heart of man. These rewards that ye may receive, obtain by the labours of righteousness and spiritual vows! Amen. (Discourse on Baptism 7)
