One may be a sinner…

Sinner one may indeed be, but no one must despair of pardon on this day which is so highly privileged. For if a thief could receive the grace of Paradise, how could a Christian be refused forgiveness?
–Saint Maximus of Turin (Fourth and Fifth Century)

We are washed clean…

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)
