Tractates on the Gospel of John

⁵ Nor need we be disturbed with the question, how the sponge could be applied to His mouth when He was lifted up from the earth on the cross. For as we read in the other evangelists, what is omitted by this one, it was fixed on a reed, so that such drink as was contained in the sponge might be raised to the highest part of the cross. By the reed, however, the scripture was signified, which was fulfilled by this very act. For as a tongue is called either Greek or Latin, or any other, significant of the sound, which is uttered by the tongue; so the reed may give its name to the letter which is written with a reed. We most usually, however, call those tongues that express the sounds of the human voice: while in calling scripture a reed, the very rareness of the thing only enhances the mystical nature of that which it symbolizes. A wicked people did such things, a compassionate Christ suffered them. They who did them, knew not what they did; but He who suffered, not only knew what was done, and why it was so, but also wrought what was good through those who were doing what was evil.
