The Treatises of Cyprian

¹⁶ The voice of the warning apostle is, “Purge out the old leaven, that you may be a new lump, as you are unleavened; for even Christ our passover is sacrificed. Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.” But are sincerity and truth preserved, when what is sincere is polluted by adulterous colours, and what is true is changed into a lie by the deceitful dyes of medicaments? Your Lord says, “You can not make one hair white or black;” and you, in order to overcome the word of your Lord, will be more mighty than He, and stain your hair with a daring endeavour and with profane contempt. With evil presage of the future, you make a beginning to yourself already of flame-coloured hair; and sin (oh, wickedness!) with your head— that is, with the nobler part of your body! And although it is written of the Lord, “His head and His hair were white like wool or snow,” you curse that whiteness and hate that hoariness which is like to the Lord's head.
