Therefore, beloved, we are washed clean but once; we are freed only once; we are received into the immortal kingdom once and for all. Once and for all are they happy whose sins are forgiven and whose stains are blotted out. Hold fast to what you have received; preserve it joyfully; sin no more. Keep yourselves as children cleansed by that sacrament and made spotless for the day of the Lord.
— Saint Pacian (c. 310-391)
