Come now, and let us reason together,
says the LORD:
though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.

What shall I say of human judgments, since in the judgments of God the Jews are set forth as having offended the Lord in nothing more than violating what was due to widows and the rights of minors? This is proclaimed by the voices of the prophets as the cause that brought upon the Jews the penalty of rejection. This is mentioned as the only cause that will mitigate the wrath of God against their sin, if they honor the widow and execute true judgment for minors. Here also the likeness of the church is foreshadowed. You see, then, holy widows, that that office which is honored by the assistance of divine grace must not be degraded by impure desire. - "Concerning Widows 2.13"
[One] who is baptized is seen to be purified both according to the law and according to the gospel. According to the law, because Moses sprinkled the blood of the lamb with a bunch of hyssop; according to the gospel, because Christ’s garments were white as snow, when in the gospel he manifested the glory of his resurrection, [one] then whose guilt is remitted is made whiter than snow. - "On the Mysteries 7.34"
Humankind has need of God’s grace not only to be made just when they are wicked, when they are changed, that is, from wicked to just, and when they are given good in return for evil, but grace must accompany them, and they must lean on it in order not to fall. This is why it is written of the church in the Song of Songs: “Who is this that comes up clad in white, leaning upon her kinsman?” For she who could not do this of herself has been made white. And who has made her white but him who says by the prophet, “If your sins be as scarlet, they shall be made white as snow”? She was not gaining any good merit then at the time she was made white. But now that she has been made white, she walks aright, provided only that she continues to lean upon him who made her white. Accordingly, Jesus himself, upon whom the church leans, now that she has been made white, said to his disciples, “Without me you can do nothing.” - "On Grace and Free Will 6"
The great physician of souls is ready to cure your suffering; he is the ready liberator, not of you alone, but of all those enslaved by sin. - "Letter 46"
The Father will be seated, having “his garment white as snow, and the hair of his head like the pure wool.” This is spoken anthropomorphically. And the spiritual sense? That he is the King of such as are not defiled with sins. For God says, “Your sins shall be as white as snow, and shall be as wool.” Wool is the emblem of forgiveness of sins, as also of innocence. - "Catechetical Lectures 15.19–21"
Why do you deck out your body while you neglect your soul, enslaved as it is by impurity? Why do you not give as much thought to your soul as to your body? You ought, rather, to give it more care. Beloved, you ought at least to give it an equal amount of thought. Tell me, please, if someone should ask you which you would prefer: for your body to be glowing in health and to excel in beauty but to be clad in mean clothing, or for your body to be crippled and full of disease but adorned with gold and lavishly decked out—would you not choose by far to possess beauty as part of the very nature of your body rather than merely in the outward covering of your clothes? If so, will you make this choice with regard to your body but just the opposite one in the case of your soul? If it is foul and noxious and black, what fruit do you think you will enjoy from your golden ornaments? But what insanity is this?
Apply this adornment within yourself and place these necklaces around your soul. For the o...
Should you have gone all lengths in wickedness, yet say to yourself, God is loving to humanity and desires our salvation.… Let us not therefore give up in despair; for to fall is not so grievous as to lie where we have fallen; nor to be wounded so dreadful as after wounds to refuse healing.… These things I say not to make you more negligent but to prevent your despairing. - "Homilies on 1 Corinthians 8.8 (4)"
Such therefore being the promises made by God to them that turn to him, don’t delay … but draw near to Christ, our loving God, and be enlightened, and your face shall not be ashamed. For as soon as you go down into the bath of holy baptism, all the defilement of the old nature and all the burden of your many sins are buried in the water and pass into nothingness. And you come up from there a new person, pure from all pollution, with no spot or wrinkle of sin upon you. - "Barlaam and Joseph 32"
