Cyril of Jerusalem, on Isa 1:18

“And then come, and accuse me, saith the Lord: if your sins be as scarlet, they shall be made as white as snow: and if they be red as crimson, they shall be white as wool.”

“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.”
